The RX only loop you're describing are VERY different from magnetic
loops designed for TX.

Interesting reviews on some of the loop antennas. I've seen W4OP
adv's for several years.
I plan to make a receive-only 630m loop (4 to 6 foot diam) out of some
surplus 1/2-inch hardline that is too old for coax use. The copper
shield should do well in a loop. I will use a preamp with it (pcb in
hand waiting for some spare time to build). Plan using a small TV
rotator and tripod mount. Advantage of the loop is being able to null
out noise sources. I transmit using 43x122 foot inverted-L.
