A little something to start off some discussion here...
Back in 1993 Rod Newkirk, W9BRD, published an article entitled "Honey
I Shrunk the Loop" in QST magazine (July, 1993). For those without
access to the article, it described a multi-turn loop antenna with a
resonating capacitor inserted at the center of each turn. The
benefits of doing so were supposedly to reduce the voltage across
each of the capacitors and to make it easier to match to 50 ohm coax.
It seems to me that the same principle could be used to construct
a "bandpass" loop that would not require retuning within a certain
band of frequencies much wider than a single-tuned loop.
Have any of you folks built one of these? If so, how well did it
perform for you?
