ST. MARKS

| St. Marks transmits with both vertical and horizontal polarisation. Curiously both components appear to be firing in the same direction as there are 4 vertical logs near the top of the tower, and 2 horizontal below them. [Ed. I suspect that the reason for the lower powered horizontal beam is to serve the area closer to the site, which may otherwise suffer from CCI from Reigate. Further away, and down into the town, terrain screening means that Reigate CCI isn't an issue for the higher powered vertical component.] Further down the tower there is a horizontal log which was for RBL of Crystal Palace. The vertical log is now used for RBL of Tunbridge Wells. Originally a BBC landlord site, St. Marks entered service on 26-May-1983 transmitting with vertical polarisation only. Horizontal polarisation was added around 1990. The site was assigned as a Crystal Palace relay. Site number 101.26. While BBC 1 & 2 were RBL of Crystal Palace, ITV, and Channel 4 from August 1983, used Tunbridge Wells to provide TVS Southeast regional programming. BBC 1 & 2 were changed to relay Tunbridge Wells on 15-Jun-2001 prior to the launch of the BBC Southeast region in September 2001. DSO was on 30th May and 13th June 2012. |
