Very good and so-so

If I were rating this antenna for it's UHF qualities, then I give it a solid 5. This is a comparison to the factory duck antenna included with the KENWOOD TH-D72 HT. But the VHF ability of this antenna is no better than the same factory duck. I have tried it simplex and standard repeater. And linked to my TS-2k via Wireless Remote and Sky Command. It is not bad. There is no audible or visual (s meter) difference between it and the factory duck. Based on the Rating scale that has 3 = Ok, then on VHF mode it is a 3. Combined with the 5 I heartily give it for UHF mode, than means the overall rating comes out to a 4. That is still very good but if your looking for gain improvement over the factory duck on VHF, this is not the antenna to do that. Since I do a fair amount of UHF work, I do use this antenna which I paid $19.95 from via HRO.

After losing my first Comet SMA-24 HT antenna and going back to the duck that came with my FT 60 I've recently replaced it ( after someone at work took a shine to it and nicked it and with snow season coming I'll be happy to have pedestrian repeater access back on 2M & 70cms

A Very Good Antenna
|
Time owned: more than 12 months

I purchased the BNC verison for my Icom V-8. It definately has an improvement over it's stock antenna. I later purchased a Yaesu VX-7R. I love this set up. See it is 17 inches long and can get in the way, but I have a chest radio harness and with the radio in the pouch and the antenna tucked in the antenna hold down loops it stays high and able to receive much better that on the belt clip. The speaker mic right by the radio and not stretched up from the belt area. The antenna performs very well and I am able hit repeaters that the stock antenna on my VX-7R cannot. The stock antenna is not bad either, but it also leaves me fearing that the SMA connector will break. The SMA to BNC adapter offers more of a stable base where it attaches to the radio and the BNC makes it so much better than unscrewing it everytime. Now just a simple twist. I love this antenna and it meets all my needs.

Definite improvement
|
Time owned: 0 to 3 months
|
I have the SMA version for my VX-7R. I definitely notice an improvement on 2m/440 both receive and transmit. I can hit repeaters with this that I normally cant with the rubber duck antenna.
It works best in the 2m/440 bands as advertised. The rubber duck antenna does perform a little better outside those bands, such as when listening to police/rescue. Since I rarely go outside 2m/440, I keep it on almost permanently.
It seems pretty durable, and from the other reviews, I expected it to be so flimsy it would droop, but its not. I like it because you can tuck it in your pocket easier and it will bend and keep its shape just fine. Its only about 4 inches longer then the rubber duck.
I would absolutely recommend it, and i'm glad I made the purchase. I think the $20 was worth it.

Decent antenna
|
Time owned: 0 to 3 months
|
I bought the BNC version after finding myself on vacation in Tennesee with only the stock duck for my Standard HT.
Picked it up at TEN-TEC in Sevierville for $22
It seemed to work fairly well compared to the stock duck so it served the purpose.
After returning home, I was able to compare it with my 8.5 inch Maldol AS-20 dual bander.
I found that 2 meter and 70cm performance was only slightly better than the much smaller AS-20.
Overall, for it's cumbersome 17 inch length, the Comet 24 didn't impress me much.

Performs great!

Works great. Super gain over the stock VX2R antenna. No problems with a year of use.
It is probably a little overpriced for what it is, but so are all Comet/Diamond products.

Flimsy and useless
|
Time owned: 0 to 3 months

I noticed no improvement with this over the VX-7R's stock duck. It made out-of-band RX almost nonexistent, and didn't improve in-band RX or TX at all.
The physical flexibility was nice, except that it just recently snapped off at the top of the base, after 2-3 months of use. Overall, this thing is a huge waste of money.

Excellent value

Time owned: 3 to 6 months

Used with VX-2R and TH-F6A. Flexible, light, good gain (important to VX-2), relatively inexpensive. In length and performance, is on par with my Diamond SRH320A... Excellent HT antenna.

not resonant at 440 barely ar 2m
|
Time owned: 6 to 12 months
|
I've had two of these antennas. When I received the first one I noticed that my HT got very warm when talking on 440 repeaters. I took it to work and put it on our antenna analyzer and found that it was not resonant in the 440 band (however it does have a nice node in the aircraft band. It's 2m performance was also sub-par. It is resonant in 2m at 150Mhz but shows a SWR of 1:2+ down around 145Mhz.
I called the distributer and they asked me to send it back. They sent me another antenna but it has the same characteristics.
This was the SMA mount version. The BNC version may resonate correctly. YMMV
