This plot is for an 80m full wave loop cut for 3.5 MH fed with over 200' of 450 balanced line. The measurements were taken with a 4:1 balun inline. The measurements were taken AFTER the balun.
A while back I ran antenna analyses with multiple feedline lengths. I recall that the SWR pattern developed a greater number of peaks and nulls as the feedline length was increased.
