AB4PP asked me about some information of my spike. Here it is for the others:
The lenght is 70 centimetres, the pipe has average 22mm and thickness is 2mm. The weight is 0.64 kilograms. I take a small hammer and the weight is 0.5 kilograms. It all works great
The mast is 10m MINI https://www.dx-wire.de/lng/en/fiberglass-poles/
I use from this mast only 7m, the center of dipole is 6.5m height. For fixing the mast I use a rubber load.
My set up takes 25 minutes to build. I use home made dualband wire dipole for 20m and 40m. It works well.
The idea is from OK1MLP and he got it from YO9IRF on SOTA marathon 2017
Firstly I hammer the spike into a ground then I insert the mast. There are two rubbers wide 70mm and thickness 4mm around the mast. When I hammer the spike together with the mast I could damage the mast. The rubbers are need because on the bottom of the mast is a bung of bigger average.
There are my activations with this equipment:
