Improve your MicroMobile GMRS two-way radio communication with the Midland MicroMobile 7.5 dB Gain Grand Vista Fiberglass Antenna System. Suitable for wide open spaces with minimal obstructions, this 50" tall antenna is compatible with an NMO-style mount that allows for use of an existing CB cable on a .5" mounting hole. Providing 7.5 dB in gain, this antenna helps cast a longer signal to transmit and receive over greater distances.
