With hindsight I would not have fitted a DAT45 here in Easternmost England. I think a good quality 18-element wideband would have been a better choice.
What transmittter is crucial. Much of Stoke uses Fenton which needs a Vertically-polarised group A aerial.
Fenton will be 2,000W/1,000W erp after switchover in September (cf 100W/50W currently) which is a 12 to 13dB increase.
