The Laird / Antenex B132S is a 21 inch long, Chrome, base loaded mobile VHF and UHF whip antenna with NMO base and spring. This antenna does require a metal ground plane. It is omnidirectional and offers 2 dBi gain and accepts up to 100-200 watts max power and operates in the 132-525 MHz range. We will cut / tune the antenna to mid (151.625) - if you would like it tuned to another frequency, please add the frequency to the notes. Frequency Range 132-525 MHz Gain: 2 dBi Length: 21 inches Spring Loaded NMO connector Ground Plane required - not recommended for most UTV's , use a No Ground Plane Antenna instead. Cut Chart Complete Cut Chart *Caution, this antenna looks very similar to our legacy No Ground Plane Antenna. Look under the coil for the "B132S" to be sure you are opening the correct cut chart. If you have "B1442NS" under the coil, you need this cut chart here.

A metal roof with an antenna mounted in the center with no obstructions (roof rack, light bar) 18" in every direction provides the farthest range. Roof Racks - Mount the antenna at the highest point of the rack. Use a no ground plane antenna. No Roof - Pick a spot in the middle of the car. The intersection of two tubes can also act as a ground plane. Mounting the antenna to a corner triangle tab and using a no ground plane antenna will work best. Do not run radio coax and intercom helmet cables in the same wire loom. RF can bleed over when transmitting, putting noise into the system. Never run coax or power cables near MSD or igniton equipment. They create noise and if the coax is too close to the MSD, transmitting can even power the vehicle off! When tie wrapping the coax to the frame, do not crush the coax. If your coax looks flattened, kinked, frayed, or worn, replace it!
