R4 MARC Server


The Park Air R4 keeps ground-to-air radio communications assets running smoothly and efficiently, so you can concentrate your resources where they are needed most.

Having the Park Air R4 at the heart of your ATM infrastructure gives you the ultimate peace of mind in your radio network. It delivers easy configuration of your network from a simple web interface – with remote testing and monitoring.

Park Air R4 also reduces your costs. Physical inspection and testing routines can be scaled down without any compromise on safety. As a result savings can be achieved, particularly when assets are situated in very remote locations.

Z4 RF Conditioning

The Z4 family of RF conditioning filters and accessories delivers the optimum combination of size and performance. For difficult RF environments in particular, the reliability of the Z4 is an asset to any ATC infrastructure.

Designed to accompany our T6 Radios, a choice of VHF and UHF manually tuned cavity filters is available. This choice is matched by all the accessories needed to create star point or hybrid combiners in any configuration.

The Z4 range includes filters distinguished by their incredibly compact size, with a dual 80mm filter package occupying the same rack space as a T6 Radio.

Our range truly meets the ‘fit-and-forget’ requirements for RF filtering and combining, requiring little if any maintenance and offering very long service life due to the inherent simplicity of the design.
