For 80m antennas, a foot on each side is a good small pruning adjustment.
For 40m antennas, 6" on each side is a good small pruning adjustment.
I know this from experience.

Starting with a new inverted V for 40 M, I cut each side to about a foot
and a half longer. So now that I can see where my SWR of 1.43:1 plots
out as peaking/bottoming out at 6.800 MHz, how do I determine how much I
should cut away on each side? Should I just cut 6" on each side and
recalculate, judging how much farther I have to cut?
Thanks.
Doug.

Of all the stupid things.
NONE of the videos showed calibration on the end of the feed. They all did it right at the side of the vna! I finally happened on a video that did it at the end of the coax n NOW its acting like it should ? FINALLY getting a swr i can figure out after chasing how many different ghosts ?
