Mobile Antenna EasyTalk NL-350 UHF High Gain Long Range Antennas for Car Radio Transceiver

I cannot recommend this antenna for its intended purpose; putting it on the antenna analyser showed a VSWR of >9.9:1 across 144-146 Mhz, in fact across the whole 136-173 Mhz, so not even usable for Marine or VHF business band either. UHF fared better with best VSWR at 2.3:1 in the 70cm amateur allocation 430-440 Mhz. I would expect 1.5:1 or better. I would normally return for a refund but will likely re-use the parts to make my own antenna for UHF use.
