The northern site was the transmitter array with four towers in line, transmitting on a bearing of about 100°.
The southern site was the receiver array with it's four towers arranged in a rough square around the bunker.
Both sites had their own Buried Reserve bunker and tower, which were situated in the fields to the east, adjacent to each array. Both reserves seem to be extant in the current GE images, hidden in small clumps of trees.
Both buried reserve sites seem to have had their towers removed by the time of the 1940s-50s photo above, the four footings for the Tx Reserve tower are clearly visible though.
All the best,
