If you want to change the boom length and (thus) remove some directors, you
would have to do a complete redesign of element lengths and spacing to get
the best performance and a clean pattern. Just because it "loads up OK" is
NO indication of the performance - gain, pattern or F/B. Don't do it.

I have been offered a Cushcraft 32-19 2m 19 element yagi (really more like a
17 element yagi) on a 23 foot boom. The boom length is a little too long
for my current arrangement and the boom also uses crossbraces which wouldn't
work good in my current setup.
I had one of these antennas up in the late 90s when I lived in Iowa and it
was a decent performer. When I had the one before I was given a second one
with it but it was missing some of the boom supports so I cut it down into a
10 element yagi or so. It still loaded up ok but didn't ever mount it so
don't know how it performed.
I am wondering if such a "modification" would be worth it on this one. Do
you think taking 6 or 7 directors (and a few feet of boom length) off of it
would affect performance much?
