Magnet Antenna, Ham Radio 144/430MHz, Omni Radiation, 2/3dBi Gain with BNC Male Connector
Dual-Band Mobile Amateur Radio Antenna with Magnetic Base
Engineered for mobile and tactical amateur radio setups, this 18-inch dual-band magnetic-mount antenna delivers 2 dBi gain on the 2m band (144 MHz) and 3 dBi gain on the 70cm band (430 MHz). Its resilient steel spring-whip radiator is built to withstand mechanical impacts, while the high-pull magnetic base utilizes any flat ferrous surface as a ground plane to minimize VSWR to ≤ 1.5:1. It features a low-loss coaxial cable terminating in a quick-disconnect, bayonet-locking BNC Male connector.
