It consists of a 110 metres (361 ft) high guyed steel lattice mast erected on land that is itself about 210 m above sea level only a few hundred metres from the coast of the Moray Firth.

Coverage includes the areas around the Moray Firth, in the Highland region of Scotland, including up to Helmsdale in the north, Elgin to the east, Dingwall to the west and the northern shores of Loch Ness to the south.

When colour UHF television began in 1970, the site was chosen over the nearby IBA owned station at Mounteagle to carry these broadcasts.

The VHF 405-line system was discontinued across the UK, and from that point for the next 23 years, television from Rosemarkie was the originally-intended four channels on UHF only.

Channel 45 was reused by the new BBC A multiplex at full post-DSO power (20 kW) and using 64-QAM with 8k carriers.
