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

[K9MA]

There's undoubtedly a trade-off between rounder and longer. I was 
thinking of a typical more or less rectangular backpack, which would 
have a circumference much larger than a 12 inch circle. A typical 
backpacking pack could accommodate a circumference of about 88 inches, 
more than twice that of a 12 inch round loop. Granted, such a large pack 
wouldn't exactly be inconspicuous on an urban hiking trail, but you 
could always put some rocks in it, and pretend you're training for a 
Grand Canyon hike.
