What about the house? Is there a chance to install a vertical antenna on
it? This is what i would do. As high as possible. And i would just start
to install something and see how it works, to improve things then. RF
current measurements are helpful, so you can see where the best
improvements can be ontained (either using more earth rods or building a
better coil or removing a tree or adding the house earth or...)
