[R-390] Broadband Loop RX Antenna

[Thomas Frobase]

Over the past six months I have been on a quest for an affordable 
phantom powered broad band antenna for RX on my R-390A.  I ended up 
building my own, but doing it in a way that I could kit up for others.  
A paper on the loop and some research links are attached. Take a look!

If you are interested I will kit up 10 additional units for others to 
test.  The price is $65 with the case and $53 without.
