Oh, I see, and one also needs to ask as resonant lengths are known for 27Mhz
how come one has to trim it in the first place. Given a good cable the vswr
should be pretty optimal unless somebody has put it very close to something
else or has a particularly fussy rig.

It is a 27 MHz vertical antenna, but the grub screw to trim the top
section did not fit, so I used a circular clip from a ball valve I had in
the pond.
