The pair of medium wave masts constructed in 1932 by the BBC.

The BBC referred to the masts as 'West Mast' and 'East Mast'.  The mast on the left of the above photograph is the West Mast, while the mast on the right is the East Mast

The base of the East Mast

The cable entering the photo from the left is a guy wire and is joined to the insulator that supports one wire of the aerial system which comprises three aerial wires secured at the top of the mast and falling gently outwards at 120 degree intervals from the mast down towards the ground.  Where the aerial wires join the insulators they then continue their downward journey, but return inward to the base of the mast where they are fed by the transmitter.

The base of the East Mast

Close-up of the base of the East Mast

Supporting guy wires can be seen on the left of the photo, while the wire entering from the right and attached to an insulator is one of the three aerial wires returning to the feed point near the base of the mast.

The West Mast

The building at the centre point between the two masts and the point at which the 'T' Aerial is fed

An insulator at the point where one of the four vertical aerial wires rise to eventually join the top horizontal section of the antenna system.

Thecentre part of the 'T' Aerial system and the point at which the four vertical aerial wires join the horizontal section.

Looking from the South, this photo shows the East Mast in the background, the guy wires of the West Mast can be seen to the left.  The centre part of the 'T' Aerial where the four vertical aerial wires join the horizontal section can be seen at the top of the photograph.  The right-hand  tower in the foreground carries the UHF TV relay aerials while the left-hand tower carries mobile phone equipment.
