Review on HYS 771 430MHz Dual Band Antenna BNC by Harwinder Duong

The antenna description lists the 136-174 and 400-480 frequency range and it will be in the operating frequency range. Tested on two radios and achieved an SWR of 6:1 - 8:1 on the VHF business band. Pulled out one of our UHF HTs and set it to a white dot (shared with amateur band gmrs 16) and got a 5:1 SWR. Add, the description says 20W but the packaging says it's only 10W and the reception is only for 120/150/300/450/900MHz (Business Band 151-158 and 462-469). I will be returning these antennas. I'd also like to add that if someone is looking at these for your ham radio band (GMRS, not sure about the ham radio bands we haven't tested on those frequencies) don't waste your time and money. Using these antennas will burn your radio.
