Description
The 02637 antenna is ground Independent, 6.5 dB Gain, mobile antennas covering the UHF 477 MHz CB Band. Its high gain produces exceptional radio range coverage over distances not normally serviced by lower gain antennas. Its ground independence maintains a stable radiation pattern in all mobile mounting applications. Its robust construction ensures excellent longevity and performance. Ideal for mounting in applications where ground plane area is non-existent or severely reduced.

Application
Mobile coverage for the UHF 477 MHz CB Band.
