VL-1501-383-CF, Omni Antenna, Custom Frequency

VHF/UHF Omnidirectional Antenna, Custom Tuned (Custom Frequency)

The VL-1501-383-CF is a Custom Tuned version of a series of omnidirectional antennas for VHF and UHF. You may order this antenna for operation at your specified Center Frequency (anywhere from 50 MHz to 300 MHz), with a bandwidth of 10% of the specified center frequency. The internal radiating structure is complementary, thus no ground plane is needed or required for normal operation.

The antenna is housed in a Fiberglass enclosure making it rugged and tolerant to challenging environments. Internally, the feedpoint is DC shunted (short circuit) and electrically grounded (if mounted onto a grounded mast/structure), offering limited electrostatic protection to equipment connected to the antenna. NOTE: due to the possible differential of potentials between the antenna ground and the shack's ground, it is always good practice to place other localized (close to the equipment) ESD protection means.
