HF Terrian Analysis of new QTH IO82RJ.

Below shows the data of the terrian and take off angle stats for my new QTH at IO82RJ in South Shropshire.
The plots show the topography in comman directions.

1. Shows the terrain at 30 deg, 100 deg and 150 deg.
IO82RJ. Blue 30deg, Red 100deg, Green 150deg.

The plots next show the take off angles for the bearings above versus flat ground on various bands using a single element at 50 feet. Light blue shows flat ground.
3.5 MHz. Blue 30deg, Red 100deg, Green 150deg.
7.0 MHz. Blue 30deg, Red 100deg, Green 150deg.
14.0 MHz. Blue 30deg, Red 100deg, Green 150deg.
21.0 MHz. Blue 30deg, Red 100deg, Green 150deg.
28.0 MHz. Blue 30deg, Red 100deg, Green 150deg.

2. Next shows the terrain at 340 deg, 270 deg and 190 deg.
IO82RJ. Blue 340deg, Red 270deg, Green 190deg.

The plots next show the take off angles for the bearings above versus flat ground on various bands using a single element at 50 feet. Light blue shows flat ground.
