[1] The site is located on the coast road between Cromer and Mundesley, 1 kilometre east of the village of Trimingham but the activity has now moved to RRH Neatishead due to the threat from coastal erosion.

Oboe worked using two stations at different and well-separated locations in England to transmit a signal to a Mosquito Pathfinder bomber carrying a radio transponder.

The site had now been installed with a Chain Home Extra Low (CHEL)/CD Type 54 radar on a 200 foot (61 m) tower.

[2] The Type 93 was originally a mobile installation (however it never actually obtained UK Dept of Transport authorisation to be allowed on UK roads under its own power and anytime it had to be moved, civilian low-loader transport specialists had to be contracted in), but at Trimingham it was fixed to a permanent mounting, due to constant cracking issues with the frame and mobile trailer.

The Kevlon dome composed of irregular polygons erected around it and became known locally as the Trimingham golf ball.

[7] As part of a major upgrade of RRH sites around the U.K. the MOD began a programme titled HYDRA in 2020 to install new state of the art communications buildings, radar towers and bespoke perimeter security.

[8][9] In July 2022, it was announced that the radar at RAF Trimingham would be moved 8 miles (13 km) to RAF Neatishead due to the threat of coastal erosion and the increased interference experienced by operators from the off-shore wind turbines; the dome was completely dismantled and removed in April 2023.
