[Antennaware] Shielded loop receive antennas.

[K9AY]

Dave,

As a 'rule of thumb' the captured signal power in small loops is 
proportional to the area enclosed by the loop.  Twice the area = twice the 
power (3 dB).

The typical dimensions given for these loops allow them to be used on either 
160M or 80M -- and as you have surmised, the loop can be larger for 160M 
only.
