To add, I would use a full 1/4 wave 9ft whip as the first antenna to test then compare all antennas on the exact same mount to that. You can then report the 9ft whip as the 0dB reference then the other antennas will be + or - so many dB with reference to the 9ft whip. I suspect all other antennas will be minus something compared to the 9ft.

I don't see any good useful info out of the test, nothing personal but that was a lot of work with little to show. If you want to repeat the test but with meaningful gain differences between antennas I will send you a tiny spectrum analyzer that I've been playing with that should measure signal levels close to .1dB. Its very easy to operate and you would set up the vehicle to test antennas maybe a block away on flat ground in field or similar then transmit on each antenna for 10-20 seconds to get a few sweeps on the analyzer and the curser will read out exact levels to .1dB. Just watch the level for a few traces to make sure its consistent then write down the number and go to the next antenna.

You can use just about any CB antenna on the receive vehicle with the spectrum analyzer connected. The analyzer will fit in a USPS small flat rate box for shipping and I will pay shipping to you if you pay the return. To set up the analyzer connect it to your antenna with adapters I will supply, turn it on, punch in a center frequency (the channel you will test on) then a span and I have been using 100KHz. After that a curser will automatically lock onto the strongest signal which would be you only a block away and the analyzer will read out the level of the curser. What could be easier? Let me know if you are interested.

Here is what the analyzer display looks like receiving me transmitting on ch 19 and I have a little 6" antenna on the analyzer for this test. You would have a higher noise floor but the signal from your transmit vehicle would still be way above the noise floor or any other signals. The frequency of the strongest signal and its exact level are in yellow at the top left of the screen. As you can see the TinySA is really tiny.

thank you for the offer, greatly appreciated.

after I get the video made and posted ( about 2 weeks generally) you can see what we did..... and see the results.
your right, this was a lot of work, WX2Watch came over at 1:30pm and I think he went home after 10:pM......he had a 90 minute drive each way.....
I've been setting up the test for a week and spending a lot on antenna's.... so it was a big undertaking.

I knew it would be a long test and be a pain to do and thought I'd like to do this once and see if I can figure out what the best magnetic mount antenna people can buy in 2025, then I could be done with it..... WX2Watch was like if you decide to do it again I'll give you hand??? AGAIN!!!! I was thinking more as to never again!
but this first attempt showed a lot of things that could possibly be improved apon.

so if I decide to do it again I'll see if we borrow the tool. again thank you.

I've seen all these data listings and DB's and other data facts and figures that I totally don't understand, on all the antenna advertisements
( I'm a very novice CB user ) I'm lucky to have this group to ask questions to.

for someone like me.... with my novice experience and understanding... it would be nice to see a video where people take different antenna's and go out 9.12 miles away and say can you hear me now? ... how does this one sound compared to the other antenna??? and see what antenna sounded the best???.... a video like that where my ears and eyes can see the difference would be very helpful...

everyone in the CB Radio hobby will tell people what great antenna to buy.... but everyone has a different opinion.... I thought this video may help some new people..... we will see how the video turns out... I have not watched a lot of the footage yet so maybe it will be useless... maybe it will be helpful... we will see in a couple weeks.

I suspect all other antennas will be minus something compared to the 9ft.
I'm just playing around with this hobby, and I find other people just playing around with this hobby... some know less than me and some know more than me... but we all just want to be able to slap an antenna on the roof and play with the radios......... we all know the best radios seem to be the QT-60 or QT-80 ( AKA 5555 N II or 6666 PRO ) so anyone in the know, knows what radio to buy... and those radios give a LOT of bang for the buck.

but no one has a solid "this is the antenna you want to use" even though the Stryker SR-A10 is getting a rep as being one of the best all around antenna's

in my test I actually showed how some of the tall antenna's will actually get knocked off my roof... and some of the short antenna's are pretty useless to use more than 4 miles .... so I have no interest in the 9 foot whip.... it's just not practicable for people to use... at least in my wooded area..... I'm trying to find a great performing antenna that people can slap on the roof and get good range with.

if everyone in the hobby and on the road had a radio and antenna that could talk and receive a minimum of 7 to 10 miles.... I truly think the hobby would be a different hobby.... but sadly if you go to Amazon and punch in CB antenna it will give you the Little Wilson and show you 10,000 five star reviews! .... 90% of those reviews say this is my first CB radio and antenna and it works fantastic!!! I can turn on channel 6 and actually hear people from all across the country... what a GREAT SYSTEM!!!!!
after a few months those same people will say that CB is dead and remove the CB from their car and tell people it was all a waste.... all because they bought junk......
so I'm hoping people will watch my video and actually buy something good that will allow them to enjoy the hobby... and I don't see people getting 9 foot whips... so I'm just using the common antenna's that the average person could buy and use.

If you do a gain type test in the future I recommend adding a 9ft whip to the mix as a reference. It may not be what everyone uses but everyone can relate to it. I would think once your set up with two vehicles a block apart and ready to test, you could easily go through a dozen antennas in an hour and have all your level info. Make out a spread sheet in advance with the names of each antenna and a place to write down the received level, then compile it at home later.

As an example you might have a received level of -52dBm on the 9ft whip. The next antenna might be -54.2dBm and another at -53.4dBm. Subtract the first antenna of -54.2 from the 9ft of -52.0 which leaves you with a loss of 2.2dB competed to the 9ft whip. The next antenna of 53.4dBm would be a loss of 1.4dB compared to the 9ft whip and so on. You can then find out what the gain or loss is of any antenna compared to another.

Regular old cb'er with regular old antennas using expert antenna test equipment, with test results interpreted by antenna expert. Unschooled and ordinary men comes to mind.

Regardless of the outcome I thank you and @wx2watch for taking the time to do the testing and expenses that were incurred both for equipment and travel. There are a lot of thing to be considered when doing antenna testing. SWR, antenna resonance (and no they're not the same always) how the radio sees that particular antenna system (final efficiency out the coax) and other things.

When we did some testing in the mid 90's, had some "funny" things occur. Our test equipment was an IFR-1200SS for the spectrum analyzer and we tested at about 3"ish" air miles. We used the same radio, and the same person in the mobile saying the exact same thing every time for the test. If I were to recreate that test today I'd probably use a steady tone to modulate the radio. All testing was done on AM on 27.225 with about a 4"ish" watt carrier. Honestly if I had that to over I would have used a different radio and used something with variable power just for giggles and grins.

There were times, the antenna that did not have the highest reading on the spectrum analyzer had louder audio. We made note of this and went back to those antennas more than once, and we got the same results every time. We NEVER referred to the antenna by brand or anything else, simply numbers, and there were at different times 3-4 people listening and they also picked the same antenna for loudness. We could only surmise that varying conditions in the actual antenna system affected the final output to the antenna. I know now, we should have done this test at different distances. Perhaps 3 miles, 5 miles, 7 miles, 10 miles and perhaps further?

Obviously there were varying SWR readings, however none were above 1.3 if I remember correctly on the chosen frequency. All were tested on a magnet mount, with either the cable that came on them, or we made a center -ring_ for the 3/8 24 mount that we used on a triple magnet mount. All were placed as close to the center as possible on a 1995 GMC Jimmy (mine) at the time.

I certainly wish I still had all those notes, and frankly if I were to do it again today with our technology, I'd do video as @niceguy71 has done.


I fully endorse the Tiny SA and a 1/4 wave whip as the baseline, that would be great. While not a $10.000.00 (or more) analyzer, the ones we checked recently (Tiny SAs) were good enough for the testing antennas like this in somewhat controlled conditions. Besides who doesn't like to have more toys to check stuff with!

That's a nice offer @prcguy has laid out to you. Actually the results are pretty much self explanatory out of the tiny SA, and not really subject to much confusion once it's set up. You'd only need post photos of it all, and I'm sure many of the guys here would gladly look at them.
Like he @prcguy said it wouldn't take long at all to key up, snap a photo and move on to the next one.

Anyway thanks again for all your time, money and effort. Have fun and keep on learning!

If there is a next test I would use FM mode unmodulated and might consider feeding the transmitter into a high power 3dB attenuator to give the radio a more constant match, mostly resistive just in case an antenna has high SWR and the transmitter starts to back off. I have an attenuator available for this.

With a spectrum analyzer other tests can be run to answer questions that have come up for years with no good answer like how much does SWR affect range? You can get a spectrum analyzer level on a well tuned antenna then adjust it for 2:1 or whatever then measure the precise received signal level again. On the IFR1200 spectrum analyzer mentioned, I think its stuck at 10dB per division which is way too crude for antenna comparison, you need 1dB/div or a peak reading cursor to get accurate measurements.

I would rather see a better spectrum analyzer used than even the tinySA, like a few HP/Agilent units here but shipping those across the country would be cost prohibitive. In my testing the tinySA seems accurate enough for what is being discussed here.

Some great additions to this thread on How, What and Why. Thx.

Initial test replicates about what most of us can acquire. A willing stranger as we go past to call out mile markers, or a friend to help as we burn gasoline. It’s a baseline from experience if the more scientific tests are the follow-up.

Thanks for the effort!

And I’m not too worried over “winner”. Too many years, vehicle types and experience. Vehicle Install Quality and Terrain, alone, change results in, “what’s louder”. “Crank that moduration, hand”

Longest antenna to greatest tip height over greatest mass of metal . .
always works.

Real World for Interstate is same, but has to respect height restriction of 14’. And stay upright. Which pretty much means for personal vehicles a 7’ base load antenna with highly flexible whip or a mid-coil (shorter) with same.

A 6’ Skipshooter doesn’t whip around like the 7’ model. But will that height reduction keep it competitive in RX sensitivity (what matters) the same as a SIRIO 5000 or my PRESIDENT Texas? Where would WILSON 5000 fit in this mix? (Stryker is re-packaged Wilson).

The change from the 108” is the interesting part.

Skipshooter is a great bargain in price. If it performs like much more expensive antennas, then our putative operator can buy 3,4,5 SS for the same price. Every family vehicle.

Below 5’ doesn’t exist, IMO, as RX/TX needs everything it can get for the scary moments. That’s the commuter compromise height. One may believe he hears all of that of which the radio is capable with under 5’ . . but he isn’t.

I’ve dozens, maybe a hundred times or more the past decade where my big truck radio was the only one who heard the other man. The drivers around me may have had comparable install & antennas plus radio . . . I had DSP.

Today, DSP masks the outer edge when Install and/or Antenna fall short. I changed from 6’ to 7’ on big truck and gained that outer edge of range where all else was unchanged. Same for my pickup going from 7’ down to 6’. Lost range.

I hope a follow-up can be done using signal analysis. Baseline 108”

the Radioddity QT-60 REALLY needed the Driver Extreme DX901 speaker..... the Radioddity QT-60 with the NRC turned on, had me straining to hear WX2 out of the back ground? ... he sounded faded and distant compared to what I normally hear on my President Grant. so if I leave the Radioddity QT-60 in my truck I'll have to find a place for the speaker...

The quality of the RX means almost as much as anything else.

This isn’t passive entertainment.

Gear: DRX-901
Install: Above left shoulder.

if I ever do it again.... ( or I screw up the video and have to repeat it) .... I'll do it when your visiting Massachusetts and you can come be part of it and do all the numbers.

geesh, I haven't made the video yet.... now I'm feeling some pressure.... I sure hope it comes out well with all the nice comments

You’ve done just fine with earlier videos.

I could say the same thing about pushing DSP and Best Install. Or the Where, What, Why of when to most often encounter big truck CB use. The paucity of online involvement by the biggest group of users is remarkable.

IOW, Do the Right Thing.

And yet, we saw the difference. In 1995 I was the only radio shop that included CB radio in the lineup of work we did in the midwest that even had such capabilities, and we gladly justified that $14000.00 price tag every time we got the chance. Obviously more resolution would be better, but after laying out the cash for that, a different SA wasn't an option. Guess we check some really "different" antennas. LOL.
I would rather see a better spectrum analyzer used than even the tinySA, like a few HP/Agilent units here but shipping those across the country would be cost prohibitive. In my testing the tinySA seems accurate enough for what is being discussed here.
Again, obviously a better SA would be nice. While now I have access to such equipment, I didn't in 95, I was carting that thing around everywhere to do a multitude of tasks with it including certifying CAP radios in addition to commercial and CB repair, locating cable fault, and tuning duplexers. I tend to agree however, this is CB radio we're talking about here. I do have a couple antennas I'm gonna actually throw on and test and see what the Tiny SA shows. I can imagine shipping would be a little high especially counting insurance to ship the HP/Agilent units. I know the last time I sent the IFR out, that alone was a fair amount of money. A couple of us just did some testing on some ham 2 meter/70 CM and 900 MHz antenna's and the Tiny SA honestly showed us what we needed. Frankly the little thing works better than I thought it would, just like the Nano VNA's actually work better than I thought they would.

I still think it's great you're willing to send him the stuff to do this with, if I had more than one of each, I would too. I loan my stuff out on occasion but usually where I can make a call and get it back pretty quick if needed. I hope he takes you up on it.

I think there’s plenty of us would be willing to help. Distance is the problem.

But I’ll bet you can if you decide to take a run at it. That’s the way I’d have to do it.

“ . . I do have a couple antennas I'm gonna actually throw on and test and see what the Tiny SA shows.”

This is where the rest of us live. It’d be a help were you to lay out procedures used.

As to understanding, some will exert themselves (Cebik), the others won’t.

Best part of online forums is the energy that gets spun up around questions of this sort. New territory for many.

The Tik-Tok-Type thinks there’ll be “an answer” and not understand that vehicle brand, model, options, install quality rigor, etcetera, mean differences. Sort of like tolerance stack.

Similar gear & procedure in use by all gets chaff blown away, in main.

Thx

The tinySA is super easy to use and interpret the results. I can send a video of what buttons to push. If you give me the antenna models to test I can send you a spread sheet already filled out except for the numbers you record off the tinySA. Overall, the test I'm proposing is much easier than what you've already done and the results will be very valuable to anyone interested.

Not sure when I'll be in your hood again, could be early next year but I can send you stuff to perform the tests at any time.

this is my K40 short.... hopefully??? it will be ok for a test ride????? this is what I sent to K-40 AKA Road Pro

1= Enfinity???? you know what I mean and so will they.

when I got back into CB I thought I would get my old 1989 CB and K-40 out of the closet... the K-40 was pretty beat from 11 years of use and I had cut the coax off of it....so I bought a new one ... I had a hard time getting the SWR set right on the K-40??...... in the meantime I watched a YouTube video of Far-point farms getting 18 miles range on a Tram 3500 and seeing the Tram was $50 bucks I bought one and the SWR was easily set and it worked fantastic... so the new K-40 went into the closet.

for the Great Antenna Test I pulled it out to use it on the test.....and learned it had a short in the coax.....

I contacted RoadPro that handles K-40 now and they said it only has a 2 year warranty? I had to send them pictures of the box showing huge writing on it saying 5 YEAR WARRANTY

then I had to send them a copy of the original invoice... luckily I still had it

well they E-mailed me today that they are sending a new K-40 antenna and a new magnetic base for it ( the one I bought 3 years ago was scratched badly)

nice to see a company stand behind their products.....

I was unable to use the K-40 on my test .... I was able to twist the coax where the short was and get a good SWR so I had hoped it would be ok for the test... but I used an inline SWR alert on all the antenna's we tested...... and sadly the K-40 had the SWR Alert screaming every time I transmitted.... I told WX2Watch I was heading out with the K-40 and he said it sounded really strong.... I got on the highway and WX2Watch still said the K-40 was sounding good... but with that SWR Alert was screaming I stopped using it.. it wasn't worth killing my QT-60 radio for a test.

so it looks like I will have a new K-40 to test for the "next" test.... I may try to do just the k-40 and see if I can add it to the video....

I know the conditions will be completely different ..and I won't have WX2Watch with his Stryker SR-A10 back at my house....and it can't possibly compare to the other test... but I really wanted these 7 antennas in the test... so I think I'll add it in.... it will let me see how a test on a different day works....

shame, as we had pretty good conditions for the day of our test.

funny things I noticed on the video's????

I started each video with the antenna hooked up to my SWR meter the RigExpert-54..... it's a good one ... very accurate .....
I recorded each SWR and none were terrible... all lower than 2.0.

I used my smart phone to record and had it sitting on the seat trying to see the QT-60 radio....

I could not see the display on the video's as I had hoped I would...... one..... as the camera on the seat was a little too far away and two the QT-60 always had a glare on the screen.... but if I look at the video on my phone screen I can zoom into and see the display.....

I was very surprised at two things.

one the SWR on the QT-60 display read between 3 to 4 ????? I tested all the antenna's on the Rig Expert and they were all pretty good before pulling out of the parking lot???
so I watched each video and they were all pretty bad... my Tram 3500 that I use daily ..... using the RigExpert it is always 1.2 to 1.5 on channel 1 and channel 40... and that's how it always is including this test..... it always does a fantastic job...... so I thought for sure that antenna would read fine on the QT-60.....
nope it was also 3 to 4 SWR????
the QT-60 I'm using in my truck ... I took that from my base station an hour before the test... it has always shown an SWR of 1.2 at max for the last year... the needle barely moves... but in my truck it was well past halfway to 3/4 way filling the meter??????

this seemed to be the same on all the antenna's with the one weird exception....

we took the Stryker SR-A10 out and the conditions just went bad as soon as we started the test... we only got 5 miles with it and I went back to the parking lot and switched to the next antenna in our test........ myself and WX2 knew the Stryker could do better... but for 20 minutes the conditions changed to allow skip to nail us and it was difficult to hear each other or anything but skip and static...... the SWR reading on the QT-60 was 3.5 SWR .......... after 20 minutes the conditions went back to normal.... but we had already moved onto the next antenna in the test....
later we did the Stryker test a 2nd time... meaning I took off the antenna we had just tested and put the Stryker back on the roof for the 2nd time...... this 2nd test I did NOT hook up the RigExpert SWR meter as I had set all the antenna's before the test and I had just checked it an hour ago before the last test and it was perfectly fine.......
when I watch the video of the 2nd Stryker test it was the only antenna that the QT-60 showed a normal SWR reading .. it barely moved the meter showing 1.2 ????
all antenna's were placed in the exact same spot... my roof is marked up pretty good...
I have no idea why the rig expert showed a very precise SWR reading for each antenna but the QT-60 was WAY off???????... all but once????
very weird

not going to worry about it as .... every test I placed the new antenna on the roof got in the truck and shut the door.. hooked up the rigexpert and saw a good SWR then I hooked the coax to my radio and drove out of the parking lot to do the test..... but the display on the QT-60 baffles me.

number two odd thing????
WX2Watch and myself set both radios to exactly 10 watts on two of my watt meters .. both showed 10 watts dead key
now that I watch the footage.... the power output on the QT-60 looks like it's going full across the display as I talk... this must be modulation? or it could be the 10 watts dead key was 40 watts with modulation and that's about what the display shows????

not sure I like the display of the QT-60 in my truck... I LOVE it on my base station... but it really acts differently in the truck.

I am working on the video guys


by the way this is just a small sample of my test.... and to show why some people will not be liking my antenna test.

by the way all the antenna's made it into and out of my standard 8' tall door garage without problems....... all but one... so I think all but one could be used for daily use.
