E field antenna height
#8
E-Field need to be outside - works if it's just over the roof. BUT it must be free from mains and other disturbances.
H-Field is pure magnetic, and since it's hard to screen magnetic fields, it works under a metal roof.

I would give ferrite antennas at least 10 cm from metal and loops at least 50cm
Metal roof should not be connected electrically to pre-amps, but may be grounded
