    For anyone interested in transmitter sites, I notice the Google car has been up to see the Limavady towers.

    Google Maps' Street View seems to have now got most of Northern Ireland done (they've even got a single-lane road with a 1:3 incline next to a family farm in the back arse of nowhere in the Sperrins photographed!) Tried getting a decent shot of Brougher Mountain but the Google car didn't get close enough to it. Ditto for Divis.

    The Strabane mast is available close up though...

    That will be another Arfon performer when they put DTT on it: I am surprised they never used these 1000ft ex-ITA masts as the main UHF stations in West Ulster and in NW Wales. Those crappy old BBC sites at Brougher and LLanddona should have been skipped!

    They've certainly been busy getting it all online in the past couple of weeks. I think most of the recording was carried out late last summer.

    There are a couple of distant shots of Holywell Hill and Clermont Carn as well.

    I know nothing about the Llanddona/Arfon problems, but Brougher Mountain isn't actually a bad site for the area it intends to serve, namely Co. Fermanagh and the western parts of Co. Tyrone and principally the towns of Omagh and Enniskillen. Official coverage maps also stop at the border which doesn't show how far its gets into the Republic (coverage in Cavan town pretty good) and mysteriously fails to show how far east it can go - some TV aerial installers around Dungannon and Lurgan I know of have said that they can bring in Brougher there where Divis can struggle, and I know from experience that FM radio can be received pretty well all the way up the M1 until just outside Lisburn.

    A few years back I used Radio Mobile to plot some broadcast coverage maps and did an experiment using the Strabane mast to see how much of an area it could cover as a UHF "main TX" site using the same TX aerial height as present (except omnidirectional) using the same present frequencies but much higher ERPs (between 100kW to 1MW) in place of the Brougher Mountain and Limavady service areas - the result was a big disappointment, Enniskillen, Limavady, Derry City and Portrush/Portstewart would require relays and most of Co. Fermanagh and the North Coast wouldn't be covered. Despite the sheer mast size, local topology causes numerous shadows of reception and too many significant areas of population in too many unserved-from-Divis areas wouldn't be covered. As Watty used to point out, what works for VHF doesn't necessarily work out for UHF. Might dust off RM to see if I can get a plot done as an example...
