WS38 Battle Aerial, these whip antennas were designed to be used as the top section with the standard F section aerials if required but was primarily for use on its own, plugging into the smaller socket in the aerial mounting block.
The aerial was designed to be less difficult to snap or bend than the standard F sections and one was issued with each set. These are now hard to find but we have been able to obtain a quantity of them which based on previous occasions we have had these, will not be around long.
