Comments: Alderney is a TV relay of Fremont Point, although BBC A and BBC B changed to being line fed in Oct 2015.

The Alderney site used to play a major part in bringing tv pictures to the Channel Islands, hence the unusual array of 4 SABRE receiving aerials which are aligned on the mainland transmitter at Stockland Hill. You can read more about this arrangement from the links at the foot of this page.

These days there ia a fibre-optic link to the islands. Much of the equipment we see installed on the Alderney mast is therefore now redundant, but certainly no less interesting for that.

The relay transmits from a conventional stack of cardioid dipoles mounted at the top of the mast. Would any tx-listers like to speculate on the functions of any of the other ironmongery?

Alderney entered service on 1st April 1977, with Channel 4 from June 1984. DSO was on the 17th November 2010. Radio Guernsey was added in 2007.

The first five photos come from Peter Lonsdale and were taken in the late 1970s. They show both the BBC logs and the IBA Sabre panels, as well as the two 9 m dishes at some distance from the main tower.
