much better than the transmit vertical.  On CE/K7CA, the copy was excellent,

I have been using a similar loop for about two years and logged more than
100 DXCC's with it. Recently I added a FO0AAA loop plus a pennant to my RX
antennas. I was surprised how well this small RX loop performed compared to
those bigger antennas. Yes, the pennant and the FO0AAA loop are slightly
more quiet, have a different pattern and are broadband but the size in
relation to performance makes the the small coax loop a very nice RX antenna
fot topband.

I have been using to classic version of the antenna, but K9DF has an
interesting version of it that I might be testing soon;
