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.
