Some years ago, activating Summit Platte (DM/BM-174) my first time, I’ve found there a large and flat summit with a huge lookout surrounded by large trees.
My first thought was to use the platform for operation. An antenna only some meters over the ground would be surrounded by much material with more or less attenuation. But I had no idea how to install one of my short wave antennas on the tower. Hanging a wire down from the top seems to be no good idea. The stairway contains much iron and the tower has also some (lightning conductors).

I saw also no way to mount the pole on the platform. The roof is larger and contains also metal. Therefor my dipole 6 meter over the ground (inverted V) was my choice. After switching the TRX on I was afraid that my equipment was broken. Only a few signals on 20 m and 40 m. With some some luck I managed 2 contacts on 40 m within 40 minutes. To save battery I made a break for 30 minutes and made then 11 QSO within 1 hour, one of my difficult activations.
Some weeks ago in 2020, activating Platte my second time, my plan was to work from the platform. From there are no radiation barriers over a long distance around.
Platte as the highest point in the region
I used my pole like a fishing pole with my “vertical” along. The second wire, the “elevated radial”, was going along the edge of the platform.
The pole was directed to west. The radiation should go to north, to south, up in the sky and down in the ground . It was successful, 7 contacts on 20 m in 7 minutes (SV, EA, OH, SM). Sorry for chasers in the east and the west. It would cause to much trouble on the platform to change the installation. Some other visitors were there.
It’s a nice experience. I hope to find some other places for my method.
