Description
The 02637 antenna series are ground Independent, 6.5 dB Gain, mobile antennas covering the UHF Commercial Radio Bands. Their high gain produces exceptional radio range coverage over distances not normally serviced by lower gain antennas. There ground independence maintains a stable radiation pattern in all mobile mounting applications. There 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 Commercial Radio Bands.
