An RAF Type 15 radar station 'somewhere in England' during the Second World War.  Although the radar aerial is mobile, being mounted on a trolley, the camoflaged building behind is concrete and looks quite similar to the one remaining at Ronaldsway.  The overhead feed to the aerial is supported on the two poles.
