Hmmm ... I use an Alexloop with my K2. Since the real part of the feed
point impedance of a single-turn small mag loop is so low, one design
goal is to reduce the resistance of the the loop parts ... larger
conductor, butterfly capacitors with no moving connection, etc. Do the
multiple turns increase the radiation efficiency enough to outweigh the
increased I squared R loss of the longer conductor?
Ignoring that loss for a moment, what is the effect of multiple turns?
Do multiple turns affect the bandwidth? Just curious, small effective
antennas are of interest now that I've moved from a 5 acre "farm" in
Auburn CA to a suburban house/lot in Sparks NV [with a somewhat
benevolent and benign HOA].
