[Elecraft] Urban stealth HF: Inside-the-backpack loop antenna?

[Grant Youngman]

Yes, it does not have to be round.  The actual measurement of interest is Circumference of whatever shape it is (e.g, the total length of the radiator).  A 12” loop or square, or whatever,  is still going to have a very low efficiency at this size point.  But closer to rounder is better …
