Dave Riley write about loop antennas: > As for the CONS, well I just don't think of any... Somebody?? > There are two 'cons' that I can think of. One is the weight of the low-loss wire required. This would cause a problem in my own case as local restrictions lead me to use a fairly fragile mast. The other is directivity in the form of two sharp nulls. I have used a loop in the past and for a short while held the 73kHz distance record using it. However, after some comparitive tests, I opted for a Marconi which at that frequency had similar 'gain' but was almost omnidirectional. In all other respects you are, of course, right.
