When used with the appropriate transmitter system, the dBs 300A fully enclosed radome antenna transmits specially formed radio frequency (RF) beams in the frequency range of 328 to 336 MHz. Aircraft equipped with the proper airborne receiving equipment can follow the glide slope signal (provided by the dBs 300A Glide Slope Antenna) and can lock on and follow appropriate descent angle safely down to the runway.
The glide slope antenna assembly consists of three collinear dipoles mounted in front of a 90-degree corner reflector, which form the shaped horizontal and vertical patterns of the antenna.
The assembly includes a temperature stabilized RF Distribution System, individual antenna element integral monitors, and a monitor combining device which provides a single monitor output. The entire RF Distribution System, as well as the integral monitor, are constructed using phase stable, semi-rigid coaxial cable which provides less sensitivity to environmental changes.
The 300A solide radome features dB Systems’ high performing, reliable 300A which is mounted in the state-of-the-art solid radome. Radiating elements have 100% radome coverage to minimize environmental effects.
The RF input (J1) and the monitor output (J2) connectors are both Type N female receptacles.
Glide Slope Support Bracket (P/N 300500-100)
Optional Position Adjusting Mounting Bracket allows ±18 inches of continuous adjustment of the antenna’s physical position in the vertical and horizontal axis.
