Major: 300-315deg beyond 8km (winter)
Minor Sectors: 205-215 beyond about 8km. 260-340 beyond about 9km suggestion of partial blockage in winter.
Minor Isolated (tower/trees/etc): Hint of obstruction at 61deg, but I can't trace it.
This 24h accumulation image during wide spread precipitation shows a typical blockage image:
Around 165 deg beyond 25km.
Distance to horizon from an on-line calculator = 39 km (http://www.ringbell.co.uk/info/hdist.htm, apparently geometric with no refraction, so add approx 10% at radar wavelength.)
New Waterford area 35km 20 deg.
Glace Bay area around 35km 44deg
Barrachoise around 27km 328 deg
Boulardarie 33km at 340 deg
Point Aconi 42.5 km at 347 deg
