Straight (Rubber) Antenna, Ham Radio 410~512MHz, Omni Radiation, Unity Gain with BNC Male Connector
Compact Fixed Stubby UHF Ham Radio Solution
This 3-inch fixed straight stubby antenna delivers unity gain (2.15 dBi) across the 410 to 512 MHz UHF band, featuring a slightly longer radiator than ultra-stubby variants to optimize resonance while remaining highly compact. Built with a heavy-duty TPE radome to survive high-impact field conditions, its isotropic radiation profile ensures reliable communication in high-reflection zones. The base terminates in a quick-connect BNC Male bayonet plug, securing a stable link to portable transceivers and RF scanners.
