Radar Antenna Equipmentmore

CHL’s radar antenna system developments are industry-proven in airport, military and coastal applications to display durability and a long product life. Some of the radar antenna equipment systems supplied have been in use for over 50 years. So far, over 300 radar antenna systems have been installed worldwide.

Operating since 1947, CHL’s team of radar antenna system experts has channelled its technical expertise into the design and manufacturing of high-performing radar equipment and antenna systems for airport surface movement and approach radar, Vessel Traffic Service systems, Coastal and River Surveillance.

Radar antennas in X-band (9 GHz), S-Band (3 GHz) and KU-band (16 GHz) antennas can be delivered to meet specific client requirements. The radar antenna systems can be connected to every type of transceiver. CHL radar antenna systems are operated at over 300 sites internationally.

Antenna Turning Units

Type ST1, ST2 and ST3 antenna turning units are available to suit individual customer specifications. All units are available in 10 to 60 rpm. Advantages of CHL antenna turning units include a low noise level, reliable performance, low maintenance requirements and rotary joints with a through-going shaft for the direct coupling of the rotary shaft encoder for the antenna bearing measurement.
