Review on 📡 Dual Band Fiberglass Mobile Radio Antenna - UHF VHF 144/430MHz GMRS Base Antenna with 15.7-inch Length and SO239 Connector for Ham Radio Devices, Repeaters, and Mobile Transceivers - Includes Antenna Mount Bracket by Joseph Elvis

Although the details say 136-174MHz, 400-470MHz on the UHF amateur bands, the SWR never drops below 1.5 and achieves SWR 2.1. The title says 430MHz, and this band is definitely better, so I'll skip that. On VHF, even though the name says 144MHz, it doesn't work very well. Works better than the amateur UHF bands, but as an antenna advertised at 144MHz, it's everywhere. I didn't have high hopes for this antenna (16" dual band with no ground radials?) and I was right.
