Er, nitpick: The co-ax lead should go from the 'A' set output on the set to the side of the variometer. The feeder to the aerial base is a plain piece of rubber insulated wire. (Leads, Aerial, No.9, perhaps - docs not to hand.) This has a Ross Courtney ring terminal on te aerial base end (to fit the Plates, Connector), and a plated brass plug/pin (as used on the wire aerials) that fits the rigid aerial base on the variometer mounting plate. The wire is also the same as the insulated type used for the wire aerial feeder: Cable, Electric, P11.

The general idea being that if you need to demount the set from the vehicle, you simply unplug the aerial feeder (and the 'B' set co-ax), the set power cable, unlock the table clamps and remove the set on its carrier. You then have a spare power cable (probably the one with Niphan plugs for a pair of 85 AH accumulators), another 'B' set co-ax and the clip-on aerial base (9A),
aerial rods/wire aerial as required, counterpoise, and you're ready to go.

(Fit the waterproof cover if wet!)
