80m Full Wave Loop SWR

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.
