As readers will be aware, I am trying to pull together the various accessories and associated equipment for my WS19 set radio. There are a lot of items and I am sure it will take a few years to get it all together. Happily I have a good friend who is very knowledgeable about radios who is helping point me towards bits I need and today’s particular item has actually come all the way from Greece where it had clearly been used by their military in the immediate post war period.
The WS19 set can use a variety of aerials, including the F type aerials I already have for the WS38 set. What it does need, however, if it is using these sectional aerial sections is a base that they can be attached to and which in turn can be connected to the Wireless set. There are quite a few different versions to find, however this is the No 10 radio base and is one of the more common ones to find with the WS19 set. The radio aerial base is a domed metal base unit, painted green:
The weight of the metal base helps with stability, but holes are also drilled around the circumference so it can be screwed down or rivetted to a vehicle:
At the top of the base is a brass screw thread that allows the aerial to be fitted and tightened to hold it securely to the base:
Internally there is a wire, connected to the brass collar and in turn to the aerial, which takes the incoming radio waves through to the wireless receiver. A brass connector is fitted to the end which in turn can be attached to the wires going to the WS19 set:
The base, when attached to a vehicle, can manage 16 feet of aerial, although only 8 feet would be used on the move to prevent it getting damaged. As mentioned above, this is one of a number of different aerial bases out there, and it would be interesting to get the full range of designs, however for now it is nice just to be able to add another piece to my WS19 setup.
Aerial Base No.10 Mk.II in fact. (It was redesigned slightly to improve the bonding of the rubber to the mounting flange, and also to allow a ‘top connection’ as an alternative to the internal ‘Pigtail No.1’ lead.)
The No.10 base replaced the earlier No.8 which used a coiled spring to retain the aerial rod – this proved ineffective as flexing on the move caused metal fatigue and the spring eventually broke, allowing the rod to bounce out. Superseded in the 1950s by Aerial Bases No.31 (for HF) and No.28 (for VHF).
