January 2010

The first picture in this set from TCPD shows why the tower is the shape it is to this day. It was originally designed for the Band 3 antenna, which carried ITV 405 lines on ch 12 with 3 kW, which entered service on 31st January 1969. Closed October 1982. The rest of the photos are from Ben Smith.

UHF TV commenced with 3 channels on 23rd March 1973, with Channel 4 from June 1984. The UHF cylinder contains a south, south west facing cardioid (200). DSO was on 11th and 25th May 2011.

BBC FM radio was added in October 1981, with Radio's 1 & 4 from 1993.










At the bottom of this picture is the BBC FM radio transmit aerial system comprising of 2 horizontal band II log periodics and a vertical dipole. The 2 horizontal logs are pointing south east (145) and west (265). The vertical dipole is roughly south (195). In this picture, the west pointing log is somewhat lost against the tower structure.


On the left, near the top of this picture we see the rear of 2 UHF receive trough aerials pointing towards Darvel. Lower, pointing slightly to the right, are 2 vertically polarised band II log periodics, which are used to receive BBC FM radio both Girvan and Divis. The direction is about the same for both.
