A lot of bang for the buck !
Great range, better gain than the standard "Duck" antenna that came with the radio.
Don't waste your money
The stock baofeng(UV-82x) antenna constantly get cleaner signal reports than this antenna. Glad it wasn't that expensive.
Adequate for 222MHz, Poor for 2M
I have several multi-band radios that include 222MHz, but of the handhelds, none have a good performing antenna that covers all the bands. I've tried several of the "triband" 8" duckies and have been disappointed in all of them.
I then ordered a Nagoya NA320A and found that while it performed better than the short antennas, the match for all three bands was bad and 222MHz was over 5:1.
This was my next attempt and while it performs reasonably well on 222MHz, it's really bad on 2M. The SWR on 223.5MHz was 2.6:1 and on 146.520MHz, it was 5.6:1.
Putting it on my antenna analyzer, it revealed why. The "2M" resonance point was at 134MHz, not 146MHz with a very sharp dip at resonance. 146.52MHz was so far from that dip, that it was almost completely out of resonance.
The 222MHz dip was much broader with resonance at 276MHz. Even so, it appears to work reasonably well at 220MHz. Unfortunately, so does the single band antenna that came with the radio.
So my search goes on.
