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