Slightly off topic but can anyone explain the workings of the feed
arrangements of loop antenna. Am constructing a loop of 1.7 meters diameter
made out of 52inch tube rolled into a loop with a 2500pf vacuum variable
capacitor. The feed arrangement will be a smaller coax feed formed into a
loop with inner and outer joined to the braid. The bit that eludes me is how
the impedance is transformed. At first sight it looks like a one to one
transformer!
