MR300 antenna description
Retevis MR300 mobile antenna extends GMRS vehicle range with a tall fiberglass whip and flexible spring base. The spring lets the whip bend out of the way over vibration and low branches, which helps prevent damage during camping and off-roading.
It mounts with the included bracket, U-bolt and 16 ft RG-58U cable, with bolts that hold firm when the vehicle shakes. Use it with compatible GMRS mobile radios, repeaters and transceivers including Midland MXT275, MXT115, MXT575, MXT500, MXT400 and Retevis RT97, RA86, RA25, RA87, RB86.
