I think there is something wrong when a 4' loop doesn't pick up DX.   I've 
had an unamplified one, 3 feet on a side, for years.  It's heard from as 
far away as Western Australia and Turkey from this location; admittedly, 
none of them recently.  No, it doesn't put out as beefy a signal as a 
random wire, or even an active whip antenna, but it doesn't have to, as a 
decent receiver should provide all the gain one needs.

One problem with loops in recent years has been the large increase in 
electrical noise generated inside the average residence, which the loop 
picks up much better than many outdoor antennas do.  Some of it, such as a 
lot  from computers, is insidious in that it is a type of white noise.  It 
appears to raise the noise floor of your receiver, and leaves you hearing 
only stronger signals, but without an annoying buzz to identify itself as 
the concealer of DX.

Just some thoughts.

best wishes,

Nick
