The antenna was strung out over a small but deep valley and I used small trees as anchor points. The antenna was about 100m long. Antenna length and a good ground seem more important than height. Build in a lot of taps onto the loading coil to accommodate the wide variations of loading required for different sites, antennas and grounds. There is a road bridge, about 35m high, across a deep valley (which is a park) in the centre of Luxembourg city - it would make an ideal LF antenna support if you could get access to it. There are lots of hills, valleys and trees throughout Luxembourg.
