Stubby antennas

[blackbelter]

Which stubby antenna would you recommend to be used with a uniden 436 monitoring a nearby 800 MHz p25 and a local UHF DMR frequencies ? Currently using a RS 800 MHz antenna with great results however would like a smaller profile antenna as well .
Thanks

I have had excellent results with the COMET Miracle Baby antenna! While it's designed for 2M/440 MHz it works very well on 700-900 MHz. It's only 1.75" long. I have one of these on a Uniden BCD325HP and it fits in my pocket. It even works inside my vehicle.

I use the BNC version of the antenna in the 2nd post for my 2m/70cm HT. I use the same RS 800 antenna on my SDS100 and swapped with my stubby. All my radios are setup with BNC adaptors so the swap is quick and easy. It looks like RSSI on my SDS100 takes approximately a 10db reduction with the stubby. Not really a big deal if you are deep into the coverage area. On the fringe its going to be a different story. Testing/comparing like this is highly variable. If willing buy a stubby and see if it works. Be prepared to sell it...

Thanks I located one in town for $19.99 as it’s not available on the Amazon site and will try it .

I would say that's the going price for that Diamond antenna.
Let us know how it turns out...

The problem with a stubby antenna is that they will only work well if your in a strong signal area for the system your looking to use it on. They are a poor choice if your looking to listen to a system that is any distance away from you.

I have been in the radio service field for many years and have seen a number of police officers that have the stubby antenna on their portables. They were complaining about the normal antenna poking them in the arm pit when they had their portable in the holster on their waist. So they switched to the stubby. But now they are complaining about poor radio coverage and or they can't be heard by the dispatcher when they try calling. Not a good thing when your life may rely on that radio calling for help.

So it's your choice to use a stubby antenna. But don't complain when you find it performs poorly, unless your real close to the transmitting antenna of the system your trying to listen to.

Great antenna on 70cm. Absolute crap on VHF.

not familiar with any commercial stubbys other than scannermasters 1 inch racing antenna (which literally is the centerpin of a bnc soldered to the actual bnc housing/shell, certainly attenuates strong signals as it says it will...) but made one myself that seems to do as well as you would expect.

Stock Uniden BNC antenna of the type that comes with the BC125AT, cut off at slightly less than half length. then covered with liquid tape. looks as good as i works.

it looks pretty...umm...unique

note: cutting the antenna coil is not a "snips"/"dikes" project. dremel and cutoff wheel. or small bolt cutters.

I use the Diamond SRH805S. Very good for Metro Columbus, Ohio area multi-casting system/issues.

I have used several 'stubby' antennae on various scanners. To me, the really stubby (like the SRH805S and Comet equivalent) are not all the great except on strong systems and nearly worthless below UHF band. They are handy if you are close by and need a small unobtrusive antenna.

I found an antenna on Amazon similar to the SRHF10 that I am liking pretty much. I put it on my TRX-1 on a recent visit to Busch Gardens (Williamsburg) to monitor their DMR system. Worked great. I put it on my 396 for some other testing and it is sporadic on some VHF signals (Virginia STARS comes and goes) but nice on my county trunked 800 system.

I think you'll like the SRHF10 for size, acceptable performance, and the 'flexibility' of the soft rubber. Is this what I would use full time, no. The RS800 seems to be one of the better all around, but its length is a bit prohibitive at times (IMHO).

Thanks for all the feed backs, this antenna will only be used locally with no expectations on distance RX.
