Chelton Limited (formerly part of Cobham)

Chelton Limited is a British aerospace and defence engineering company. It is based in Marlow, Buckinghamshire, in the United Kingdom. The company designs and makes antennas, avionics and land communication equipment. Its products are used on civil and military aircraft, vehicles and ground sites.

The company was founded in 1947 as Chelton (Electrostatics) Limited. From 1989 it was part of the Cobham group. Chelton says it has more than 75 years of experience in the aviation and defence industries. Its business units cover antennas, avionics, land systems and compact platforms.

Chelton makes airborne antennas for aircraft. These include communication and navigation antennas, RF components and conformal antenna suites. Its antennas are fitted to aircraft such as the Eurofighter Typhoon and the Korean KF-21. The company says it delivered its first complete antenna suite for the Tornado in 1967.

Its avionics range includes airborne TETRA radios, anti jam GPS systems and electronic warfare systems. It also makes direction finding systems for search and rescue. Its aircraft electrostatic dischargers are another product line.

On the ground, Chelton makes vehicle intercom systems. Its AN/VIC-5 digital intercom is one example. The company says more than 140,000 of its vehicle intercom systems are installed around the world. It also makes explosive ordnance detection equipment. Its microwave antennas are made at its Newmarket site. They include Link 16 antennas and electronic warfare antennas for vehicles, fixed sites and dismounted use.

Chelton works with militaries and agencies across the world in aerospace, aviation and defence. Its sites are in Marlow, Cheveley and Newmarket, and it has a North American sales team. The company does its design, testing and automated manufacturing in house. It uses robotic cells to raise its antenna production.

Chelton's milestones include an airborne TETRA solution in 1995 and a selection to supply antennas for the Eurofighter Typhoon in 2000. In 2017 it received a contract from KAI for the KF-21 conformal antenna suite. The company's site shows EASA and UK Military Aviation Authority approval logos.
