[K6BW] Small Loop Antennas

[Bill Smith]

Having trouble with antennas?  Here is a great resource regarding small loop
antennas (without too much myth).  Beware many small antennas, they are
reactive blobs at the end of a feedline.  By tuning them with an antenna
tuner, one can set up a high SWR on the feedline which causes the feedline
to act as a radiator.  Yes, you can make contacts with your feedline, but is
that really what you expect from your antenna?
