Understood and an interesting exercise for narrow band
listening, however, for general listening this would be a difficulty with the
loop at any distance, so the loop antenna looks the one for that.

Comparing CCW receive-only antennas
The amplifier in the HF Active Antenna has very high impedance inputs to
match the capacitance of the whip antennas.
Running a wire loop between the two inputs wouldn't work very well due to
the impedance of the wire loop being very low. However if you resonate the
loop with a variable capacitor as a parallel tuned circuit it would match the
amplifiers and should work very well.
I'm not in the workshop at the moment or I would try that out. Looks like
the very first job I'll be doing tomorrow morning!
