My question was prompted by an item on the "RAF Trade Group 11 memory corner" where the "West Raynham Control Tower" group posted this query: An appeal for help with a little project. Our UHF biconical monopole antenna now has a practical use! Can any radio enthusiasts of ex RAF signals experts tell us what the coax connector required for this is called? Apologies for the missing bar on the LCD of the Vernier caliper! The thread is 37.6 mm in diameter! Photos

This is the UHF antenna to which I referred (picture in original post has disappeared)

A friend is trying to ascertain what type of co-axial connector/cale is used with this UHF antenna, can anyone help?
