|Carnmoney Hill was built due to what I've named the bowl effect. Newtownabbey is shielded from Divis by Cavehill, a rock outcrop in North Belfast - like a cereal bowl with a hill in the middle. Newtownabbey is sandwiched in the valley below and can't receive Divis.|
The vertically polarised FM trnamissions are from the end-fed antenna at the top of the tower.
I've included an image of the next-door site known as Glencairn, Glencairn was the original site for television before Divis was built. These days the site is still broadcasting Channel 9 local television at 1kw. It's known today as Ballygomartin. The top of Divis is just visible to the right of the tower.
Originally a BBC landlord site, BBC 1 & ITV entered service on 7th December 1973. Unusually, and probably due to the troubles in N.Ireland, at the time, BBC 2 was added later in 1975. Channel 4 was added in June 1983. DSO was on 10th and 24th October 2012.
BBC FM radio entered service on 20th January 1992. City Beat launched on 4th April 2007.
|Reception at this site certainly seems to be a bit of a struggle. There is, just about, line-of sight to Divis -as the last photo on this page shows - but ghosting and multipath must be quite severe as an 18 element yagi is used for the UHF feed and 4 spaced yagis are needed to clean up the FM stereo signal.|
