Review on π» High-performance 2 Pack AR-771 Tri-Band Radio Antenna for Baofeng UV-9S, BF-R3 and More β Ideal for Amateur Ham Two Way Radio Enthusiasts by Keith Norred
I have a bad ABBREE AR-771 transmitter antenna killer?
Has this thing been tested before? S11 reflection sweep included. Marker 1 corresponds to 146 MHz, marker 2 to 224.5 MHz, marker 3 to 442.6 MHz. SWR on 2m is very bad 10:1; OK 3:1 at 220M; OK 2.4:1 at 440MHz. They completely missed the 2 meter setting. Not recommended, gladly again.
- Good stuff
- Market availability
