As for non-resonant or resonant coupling you have to enlighten me:)
It's a not very scientific way of differentiating between the broadband non-resonant receive loops that usually have an amplifier attached, and which typically tend to be the type that is most discussed on this group, as opposed to the 'tuned' or resonant loops that tend to be more associated with transmit and receive, which generally tend to be discussed more on?
[email protected] Personally I'm not a great fan of tuned transmit loops on the upper HF bands, as they don't seem to offer much that can't be provided by a much simpler dipole of modest size.
However if you haven't got the space to erect full sized antennas, they can be good choice on the lower frequency bands.
But, and it is a big but, only if they are engineered properly, which is not a simple task.?
On the other hand, broadband active receive antennas are a very good choice for folks living in cities and towns, especially where space is limited and there is noise and interference present.
However if you do have the space it is difficult to beat a full sized antenna, mounted at a decent height above ground, and sited well away from property and other sources of interference.
