Base Station Ground Plane VHF Antenna Kit w/Fibreglass Antenna

Base Station Ground Plane VHF Antenna Kit w/Fibreglass Antenna

Airband Ground Plane VHF Antenna Kit

The GP124 is a omnidirectional unity gain ground plane Airband antenna ideal for local area coverage when a high gain antenna is not required or justified. The broad vertical beamwidth offers excellent null fill for consistent signal coverage.

The GP124 is a 0.85 meter 1/4 Wave Fibreglass Whip Antenna with 3x perpendicularly mounted 1/4 Wave Stainless Steel Whip Antennas that has a 300mm x 20mm diameter stainless steel base tube for mast mounting. The antenna is supplied with a 200mm Coaxial pigtail featuring a waterproof FME Male Connector. Included in the kit is a 10m feed cable with waterproof FME Female Connectors on both ends. There are 2 types of FME adapters supplied for connection to either a handheld VHF radio or a base station VHF transceiver.

Electrically, the GP124 antenna is a quarter wave radiating element with the radials acting as a counterpoise. These 3 radials are SW124 Stainless Steel Whip antennas and utilise a unique single bolt screw attachment design. The antenna is DC grounded for superior lightning protection and the reduction of precipitation static noise.

APPLICATIONS:

Airfield VHF Pilot Activated Runway Lighting Systems
Close Contact Airfield Operations
Maintaining reliable radio communications with aircraft in the circuit pattern

Aircraft positioned directly overhead a Vertical High Gain Antenna often experience a 'blackspot' in communications that inhibit clear and effective radio transmissions until they have passed by. The GP124 eliminates this shadowed area keeping VHF signal strength at a maximum for both transmitting and receiving.
