link, using refurbished equipment that provided the original picture feed for the Wenvoe Transmitter on the British Telecom Microwave Network. A site for this near Alton, Hampshire was acquired and named after a nearby pub: Golden Pot. Here the TV signal from Alexandra Palace was picked up and relayed via a one-hop 4 GHz microwave link to Rowridge. This was brought into service on 18 October 1954. Later, the microwave link ran from the Museum telephone exchange in London to Rowridge, using Golden Pot as an intermediate site. In 1965 the UHF antenna was added making the total height of the structure . This addition allowed Rowridge to radiate the PAL 625-line transmission that allowed broadcasts in colour and eventually stereo sound, using NICAM. On 25 March 2009, Channel 5's analogue signal was turned off from Fawley Power Station. Later on in the day, "existing digital terrestrial TV services moved to new frequencies", due to the digital switchover happening in the region in 2012. Arqiva applied for planning permission to replace the existing 150m (492') mast with one 187m (614') high on 22 May 2009.
