Jerome,
I have been using degaussing coils as VLF (sub 30KHz) antennas for
reception of sferics. They work very well down low. With the ~0.047
uF input capacitance of my AD620 preamp the coil scavenged from a 27"
TV (about 1 meter across) resonates at about 6.3 KHz. I have tried it
with my Jackson Harbors LF up-converter with lackluster results
probably due to severe mismatching. Haven't tried it at MW or HF yet.
73,

Has anyone done anything with a degaussing coil loop antenna?
Took a 27 inch Sony apart and the coil is something like 4 feet
across. Hooked it up to my Sony ICF2010. First thing I noticed was
very little background noise. Second there was QRM on 160 meters, 80
meters was very good. Performance started to drop off at 7 Mz, but
still useable. How are they constructed, do you treat them like a
coax loop? Any thoughts would be appreciated, Jerry
