E/M 0db 144-174 MHz WB Ant NO TUNE wide band antenna, with an instantaneous operational frequency of 144-174 MHz. The antenna is designed to meet the increasing demand for high performance wide band VHF operation, for federal, state and all government agencies. operating with a fixed 30 MHz instantaneous operational band. The EMFLX-M10008-WB provides a 50% increase in bandwidth over traditional broadband quarter-wave antennas, operating in the VHF LMR/Public Safety bands. Traditional VHF broad band quarter-waves can provide approximately 16-20 MHz of bandwidth at 2:1 VSWR for various band segments, when properly field tuned by the installer. The EMFLX-M10008-WB provides 30 MHz of fixed bandwidth for 1.8:1 maximum VSWR, and does not require cutting/tuning by the installer, saving valuable time and installation costs.
