[Elecraft] Portable Antennas (mag loop)

[David Cutter]

It will be quiet on receive and quiet on transmit, however much power 
you put into it, until it melts, that is.  I'd love to know where he 
gets his efficiency figures - perhaps you can ask him.  Putting steel 
washers at each aluminium joint turned me off completely along with the 
dinky receiving capacitor.

I'm quite taken by the Midnight Loop from N2APB and N2CX, mainly because 
I built something similar 20 years ago, only a lot bigger!  See
