How good is magnetic loop antenna, may be with amplifier for receive only, in REJECTING man made noise, especially at or near city area, with huge number of SMPS, florescent lamp etc. at people's home?
Loops like this have a very broad "figure of eight" pattern, with deep nulls, so they can strongly reject sources in the nulls.
