Review on 📻 HYS-771 144/430 MHz Dual-Band High Gain Handheld BNC Antenna - 15.6 inches - Compatible with ICOM V8 V80 V80E V82 V85 F3S HT-66 VHF/UHF Radio by Jesus Gallagher

I was pleased to order this antenna for installation on a BTECH DMR 6x2. Unfortunately, there is no part of the diagram on NanoVNA that can be confused with the resonant. The best I could get was way down at 1.7 and up from there as I tuned through the range. So you say, hey, maybe you bought a bad one. No not much. I actually bought two for different radio sands, both are similar in SWR. Aside from the SWR, I didn't notice any noticeable increase in gain over the standard antenna that came with the radio. real exam? Well, apart from the high SWR, it works as expected.
