Major
Minor Sectors: 60-110 deg partial blockage. In fact it looks a bit as if weak partial blockage from 340-110 deg.
Minor Isolated (tower/trees/etc): 23 and 332 deg
On Google Earth, I see 3 nearby comm towers measured as: 370m@24, 580m@224, 260m@331
This 24h accumulation shows typical blockage pattern (reduced radials):
Occasionally immediately off shore to the west.
Distance to horizon from an on-line calculator = 20 km (http://www.ringbell.co.uk/info/hdist.htm, no refraction)
