My QTH is in south west Germany ~30 km north of the lake of Konstanz or the Swiss/Austrian border. There is a small mountain area called Swabian Alps and my QTH is on the top of a hill at a height of 850m.a.s.l.
Take off is nearly 360 degrees free with no much higher points very closer than 80km except the Black Forrest at ~250 – 270 degrees but this is not limiting me much. All other higher points are >120km away.
Have a look at the take off profile
