I have a number of M2 antennas and I have only had one problem. I called
them and they corrected it immediately by shipping the correct part. I
have difficulty believing they won't correct a mistake they made. I did
call them about mistakes in parts supplied with one of my 9 element 6 meter
beams, but it turned out I was misreading the directions and all the parts
were correct.

I'm not a Yagi guru or an EZNEC modeler. Can someone tell me what 1/16
of an inch in element length means in performance parameters in the

seem to make much difference.
this is a 432 MHz antenna with a lot of elements where the elements are
about a foot long overall.
1/16" if it's on both sides, is shortening the element by about 1%
The element lengths are critical to getting low side/back lobe
performance, although it doesn't change forward gain very much.
As you note, on something like a dipole, a change of a few percent doesn't
change the performance all that much.
