The dBs 300A High Gain is a premium performance Glide Slope (Glide Path) Antenna offering a main beam gain of >12 dB/iso.
Engineered and built on the legacy of all dBs products, this antenna delivers consistent, phase stable RF signal in the world’s most severe locations, such as Cold Bay, Alaska.
Each antenna is phase matched and tested to meet the current FAA standards for low ceiling and limited visibility landings.
The 300A High Gain has a removable dipole channel assembly. This feature minimizes the need for adjustment following antenna replacement, as the corner reflector assembly can remain in place on the tower while the channel assembly is removed and replaced.
The Glide Slope High Gain antenna assembly consists of three collinear dipoles mounted in front of a 94-degree corner reflector, which form the shaped horizontal and vertical patterns of the antenna and provides a high gain main beam.
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 RF input (J1) and the monitor output (J2) connectors are both Type N female receptacles. Glide Slope Support Bracket (P/N 300500-100) is an optional position adjusting mounting bracket which allows ~18 inches of continuous adjustment of the antenna’s physical position in the vertical and horizontal axis.
