More Information

This antenna is equivalent to the Motorola AN000131A01 all-band antenna and operates over 153-157MHz for VHF, 440-470 MHz for UHF & 750-870MHz for P25. These antennas are stud mounted, thru-the-roof for maximum performance (not NMO) and include 17 feet of low loss cable, pre-installed. This antenna sits BELOW THE LIGHT BAR so it is not affected by parking garages or low hanging branches and DOES NOT need to come off in the car wash. This antenna mounts to ANY public safety vehicle, including Chevy Tahoe, Dodge Charger or Durango, Ford Explorer PIU. (Ford Explorer gasket sold separately, click here RBDM-GASKET)
