>"That is a pretty poor SWR curve for a 4 element Yagi."

As a point of observation, measured SWR of our full-size M2 4L 40m Yagi is
1.1:1 at 7.0, rises to 1.3:1 at 7.1, then peaks to 1.5:1 at 7.2.  As
expected, it drops back to 1.3:1 at 7.3 owing to the length and spacing of
the inner director.  Height AGL is 140 ft.
