A recent USA FCC ruling allowing amateur operation near 5 MHz has an unusual requirement; the operator needs to know the gain of his antenna (or maintain "calculations" modeling the gain), so as to abide by an ERP limit. Perhaps some European hams must also do something similar. I wonder if ham antennas (and/or their supporting towers) in the EU might be considered as structures, and subject to some mechanical requirements. This might be similar in class to flagpoles, overhead signs or light poles.
