Applications:
The VHF Omnirange Test (VOT) Antenna is designed for use in airport test facility applications. The test facilities transmit a composite test signal for calibration of aircraft VOR equipment.
Features:
The antenna is designed as a low-power transmit loop implemented as a stripline device on a fiberglass circuit board substrate. A second closely coupled monitor loop is incorporated on the circuit board. The monitor loop provides a -5.4 dB output sample of the transmitted signal to appropriate monitoring equipment.
Characteristics:
The antenna is housed in a protective aviation orange radome constructed of LP-383 fiberglass with a durable gel coat finish. Mounting provisions are for a standard 2.5″ support pipe. Interface connectors for the transmit and monitor loop are Type “N”.
Options:
The antenna has integral wiring and grounding provisions for a dual obstruction light.
