    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

I will be retiring my Sirio GPE 27 ground plane that I got in January. It has been a great antenna, but it's time to upgrade to something higher gain that will handle more power if the occasion should arise.

I have a Super Scanner and an Astrobeam coming soon, but I wanted to upgrade to a better omni. I had planned to replace it with a Hy-Gain Super Penetrator 500 reissue, but they're on backorder everywhere. There was one Vector 4000 left on Amazon for $214 shipped, and it will ship immediately.

Anyone here ever try the latest version of the Vector 4000?

The Sirio Vector 4000 3/4 wave beast is now installed, and holy cow! This thing is a monster and almost dwarfs a Penetrator. The ears on this antenna are incredible. Makes my GPE 27 5/8 wave ground plane seem like a K40.

The stations I talk to noted, and I quote, "one hell of a difference "

My son's first reaction was to ask if I was trying to compete with the local radio station, lol. This thing is huge.

Am pleased for you on the upgrade.

My “home” (I’m nearing retirement and am slowly restoring an aluminum travel trailer when off the road), won’t be using an antenna such as this; it’ll have to be something portable (tripod) until I mount something on the roof that will lay flat for travel. (Still won’t be close to a V-4000).

Get sonny boy to run the radius-miles circles from your home where map coordinates coincide with roads crossing those lines. As a benefit to your neighborhood it’d be a good thing should other services fail. (I believe you see my thinking).

CB is criticized by those who (a) have an agenda against the rest of us; or (b) who simply parrot bad advice on family comms.

It isn’t the best or the (whatever), but it’s darned effective for what it is.

“Proving out the antenna” (sorta like field strength charts) may matter some day. Ol’ Fred can hear me (tested) once I’m inbound past the hardware store near RT-7.

This may appeal or not, but I am one who wants family to have an understanding of the REACH of CB in the local environs. (That other means of communication can be at hand is neither here nor there).

A truck driver acquaintance of mine is looking to get an antenna high up at home to test both AM & SSB to have the grandkids see who could get Granpa on his mobile the farthest out when he’s called to say he’ll be home tomorrow.

Over time he’ll be inbound from at least three cardinal directions. Getting GPS coordinates is simple, thus.

Were I in your shoes I should like to know the lobes and nulls (so to speak) of the locale per mobile comms. The apparatus isn’t a directional beam, so “reading the local geography” adds a whole other aspect to operation.

You touch on some very important subject matter here, particularly if the excrement ever hits the fan. I do agree that CB is unfairly criticized by those with an agenda - be they elitist hams or anyone else. I have found CB to be vastly improved from my time on the air some 25 or more years ago.

I like CB radio because it presents me with a challenge. I must learn how to pick and use the RIGHT equipment. I must learn how to tune it to maximize my reach.

I'm not using a walkie talkie to key into a repeater and letting it do all the heavy lifting. To me, that's not much fun.

With my previous antenna, the Sirio GPE 27, I was able to talk to base stations in all surrounding counties, and sometimes even two counties away. I presume that this antenna upgrade is going to afford me noticeably greater distance, having switched from an antenna that was 17/18 feet to something 30+ feet tall.

Since I have become somewhat of an antenna junkie, I converted one of my old heavy-duty PA speaker tripods to accept a 10-foot mast pipe and I am able to portably mount base station antennas about 13 feet off the ground, from the base of the antenna. While not optimal for permanent use, in a pinch it works quite well. It makes tuning a lot easier.

My Sirio GPE has telescoping elements that do not fully separate. I could, with ease, keep it in the trunk of my vehicle with the speaker stand and mast pipe and easily add mounting screws to lock the elements and set up a portable station with more gain than a mobile antenna pretty easily.

I had a Super Penetrator 500 on this stand a couple of weeks ago, and with a Uniden handheld CB talking to me in my mobile, there were no dead spots anywhere in the city. In many cases, I could not fully squelch out the handheld station.

I'm sure you also saw that this weekend I procured a vintage Super Scanner and tower that I am doing a full restoration on. I am going to construct and mount a 50-foot tower for the Super Scanner. I have also created a few dipoles out of heavy household extension cord. One will go in each vehicle and one is going up in the top of my pine tree as an emergency backup antenna.

I am really enjoying being back in the radio hobby.

Versus 25-years ago the Internet has made it easier for the Eleven Meter guy to try and search out solutions. Noise, 120V station grounding, etc.

My being tempted by the WEST MOUNTAIN RADIO CLEARSPEECH DSP SPEAKER was a $200 leap into the unknown. But I could hear guys the others around me couldnt with equally good or better rigs the instant I plugged it in.

Same is now true for trying ferrites, filters, etc.

I’ve been slowest on test gear. PEP Meter on its way.

So, my take is that (borrowing from licensees) that MOBILE CB RADIO is MORE than the next 10k guys believe it to be.

Their experience is too narrow (or confounded by bad installs, etc), AND it is out-of-date.

The GPE 27 is rated 0dBd gain or 2.14dBi. The Vector 4000 is rated 2dBd or 4.15dBi or 2.0dB more gain. If someone's S meter is actually calibrated at 6dB/S unit then the difference between the antennas would be a little less than 1/2 S unit. That would be very noticeable but not earth shattering. It also depends on where the gain lobe is and the mfrs don't tell you that. It could be 2dB gain at a 20 degree angle upward and nothing at the horizon and two identical gain antennas could be completely different at the horizon as received by locals.

BTW, the Vector has the highest rated gain of any omni CB antenna from Sirio.


The Sirio Vector 4000 3/4 wave beast is now installed, and holy cow! This thing is a monster and almost dwarfs a Penetrator. The ears on this antenna are incredible. Makes my GPE 27 5/8 wave ground plane seem like a K40.

I don't know what the metric is for "one hell of a difference," as it is a subjective assessment. One station was my friend with the Penetrator. Another was a buddy of mine who drives a Ford E350 van with a little wilson center roof, toward the front, with an Icom 706. The other was a local who I talk to regularly who was mobile, on his way home to a small village outside of town. He has a President Bill and Little Wil antennaon his car. Usually that's when and how I talk to him

I did notice that I was pulling the guy on the Bill in much better as he was departing town. Where I would normally start losing him to noise, he was well above the noise.

I wonder if the sheer height increase of the antenna is a benefit as well. The base of the antenna is at almost 35 feet up. That would put the top of the antenna at at least 63 feet, whereas the GPE 27, at 19.5 feet, would max out around 54 feet.

The Penetrator claims 5.3dbi gain. Is that a believable figure, considering this antenna is around 33 feet in length and the Penetrator is 22 feet?

All I can tell you is that this Vector is rocking my radio world. What a wonderful antenna.

The Penetrator is 22ft 9in at 27MHz and the Vector 4000 says 8480mm or 27.82ft long. The Vector 4000 appears to be a 1/2 wave antenna with a 1/4 wave choke skirt at the base making it 3/4 wavelength long. Its kind of like a J-pole but the 1/4 wave skirt could improve the radiation pattern and/or pull it down towards the horizon a little.
