Works Well
Compared it to the AR-771 and the stock antenna on a retivis A3. The Diamond out performed them. Very happy with the Diamond 77CA antenna. The prefix determines the connection type. SRH is male, SRJ is female, RH is BNC. Make sure you order the correct one.

Best antenna Ive ever owned.
Best HT antenna out of all the different makes and models I own. Instant difference in clarity and reception the moment i put it on my handsets. I have several different HTs and its improved TX/RX on all of them, even the budget models work like more expensive HTs with this antenna fitted. As anyone who is into radios knows, its the antenna that makes the radio.

Great on UHF, VHF is mediocre. SWR values in review.
Some have called this the gold standard of antennas. While I like this antenna, I don't know if I'd go that far. Don't get me wrong, it's a great antenna and I would recommend it, it could be better. One area you won't be disappointed is receiving. This is hands down better at picking up a signal than pretty much any stock rubber ducky type antenna. The VSWR for some frequencies is stellar, but within the VHF / UHF band, it does have some high reflection values. Definitely better overall on the UHF band. I tested the antenna using a Sain Sonic AW07A Antenna Analyzer in case you are interested in the SWR values. 136MHz: 4.5 140MHZ: 1.3 140.985MHz: 1.1 145MHz: 2.7 150MHz: 4.7 155MHz: 6.4 160MHz: 7.7 165MHz: 8.7 170MHz: 9.0 174MHz: 9.6 400MHz: 2.6 405MHz: 2.1 410MHz: 1.6 415MHz: 1.5 420MHz: 1.8 425MHz: 1.9 430MHz: 2.1 435MHz: 1.9 440MHz: 2.0 445MHz: 2.1 450MHz: 2.2 455MHz: 2.4 460MHz: 2.7 465MHz: 2.9 470MHz: 3.0 475MHz: 3.1 480MHz: 3.2

Works Great on Yaesu FT-65
These work great on our Yaesu FT-65 handhelds. Seems to improve clarity with improved reception. Would probably work well on the rest of Yaesu's handheld lineup.

Excellent Anytenna.
Very Good quality Antenna, I do not see any issues with this unit and is well worth the cost. Antenna is very very flexible. I would recommend this Antenna. I may follow up in regards to how I like it and any specific notes once I have a chance to really put it to good use!
