Straight (Rubber) Antenna, Ham Radio 410~512MHz, Omni Radiation, Unity Gain with SMA Male Connector
Ultra-Compact Fixed Stubby UHF Ham Radio Solution
Engineered for close-range UHF communications, this 1-3/4 inch ultra-compact stubby antenna offers unity gain (2.15 dBi) over the 410 to 512 MHz band. It functions as an isotropic radiator with a broad spherical pattern, mitigating signal dropouts from polarization mismatch in complex physical environments. The rugged, rigid-straight TPE radome minimizes mechanical strain on terminal ports. It terminates in a standard threaded SMA Male (Plug) connector for direct, adapter-free connection to handheld transceivers.
