Good evening
They are the masts from Rugby radio station. The larger 12 masts have long gone but the many smaller SW ones still remain. There is no aerial network connected to any of them and are all redundant along with some derelict feeders on poles scattered around the site. The main radio station (C building) has been stripped of all transmitting equipment and is a file storage facility for BT.
There are several plans and schemes to clear the site of masts and build houses and light industrial buildings along with the expansion of the Daventry rail freight centre as the radio station site and aerial fields are located directly on the A5 and the M6 and M1.
There are now no transmissions from either Daventry or Rugby radio stations
