I too thought some sort of feeder for a dipole...could be horizontal as the clamps rotate.

and thanks....while photographing the coax I saw another 'Z' No. on one of the chopped leads. (initially i assumed it was the complete leads stock number.)

therefore I suspect the initial ZC 14116 is for the 2 prong plug with;
ZC 12795/10 for the clamped 'Y' fitting.

Dipole for a radar?

cheers,

Co-ax pretty much came in with WW2, the UHF and Pye connectors were pretty much standard until things 'improved', with larger/heavier connectors for external use or field equipment. (e.g. Niphan connectors on army radio where the connection needed to be watertight and be assembled with wet/muddy/gloved hands.

Early radar operated at surprisingly low frequencies! The early sets operated on 54 - 84 MHz, SLC (Search Light Control radar was I think around 160 MHz or maybe 400), and so aluminium tube dipoles and small arrays would have been the order of the day.

Chris. (I googled for GL Radar!)

brilliant sleuthing, thankyou Chris.....

I know the Silent Key was an early (1950s) Guru on the WS10 and radar, we had a WS10 set-up on the coast near here.... and then he went commercial and opened a repair and component supply shop...so he had some fascinating kit at his SK sale.

GL/Radar seems, now , very very likely.....

now to find someone operating or restoring one.
I even have a Broad Arrow marked cavity magnetron.

Thanks again for your insights.
