I've not seen much mentioned about using a magnetic loop as a receiving
antenna. I built one for 80M that was a 6' diameter made with PVC and found
it
to be a fabulous receiving antenna, I could clearly receive signals that were
well below the noise on the dipole.
My loop consists of 18" strips of thin double-sided pc board and are bolted
as well as soldered together to make a very flexible conductor that slides
inside the PCV. It is about an inch wide. The antenna transmits quite well,
but the variable capacitor I used would only handle about 20W before arcing,
so was unable to see how it did at full power (100W).
Any thoughts on using this type of antenna for receiving? On 80M it seemed
to show good directionality in the plane of the loop. Would something of
this size with a larger capacitor be effective?
