Description

Applications:

Glide Slope Antennas are used to provide vertical guidance to aircraft during approach and landing of an aircraft under instrument fight rules.

Features:

The Glides Slope Antennas are designed to withstand 100 mph wind, 1⁄2-inch radial ice, temperature range of -50oC to 70°C, and 100% humidity. All elements are equipped with de-icing heaters and thermostats.

Characteristics:

Glide Slope Antennas operate on a frequency of 328 to 336 MHz on a nominal impedance of 50 Ohms and power up to 50 watts. A null reference glide slope antenna system is fed by two transmitters, one on the carrier frequency and the other on sideband frequency. A capture effect glide slope antenna is fed by an additional clearance transmitter. (Refer to FAA Handbook 6750.6 for more information on null reference and capture effect systems.) A null reference glide slope antenna system consists of two antenna arrays, an external RF network, and a 40-foot tower equipped with safety climbing rail and obstruction marking and lighting. A capture effect system is a null reference system plus an additional antenna array, 20 feet of tower and a clearance cancellation bridge.
