Simple Ham Radio Antennas--Magnetic Loop Antenna

If you're having difficulty viewing this video, please insert this title URL into your browser search box: This is post #1007 in a continuing series of "Simple Ham Radio Antennas." For radio amateurs living in deed-controlled neighborhoods (HOAs and CC&Rs), a magnetic loop antenna may be the way to get on the air without the "housing police" getting suspicious. Magnetic Loops are fairly simple to build, "stealthy", and portable. In this video from George Becht (N2SQ), we learn how to build an effective magnetic loop antenna with readily available parts. According to George, the outer loop is made from RG-8 with teflon dielectric, using only the coax shield. The inner loop is made from the same type of RG-8, but is only 1/5 the size of the outer loop. George says the 25-100 pf air variable capacitor was "bought at (the) Orlando HamCation in 2014 for $2.00." While a magnetic loop won't have the same performance as a full-length dipole antenna, it will get you on the air with a decent signal. Magnetic Loop Antennas are ideal for apartments, portable, and emergency operations.
