[TowerTalk] More from the M2 antennas quality control file

[TexasRF--- via TowerTalk]

Norm, this may be out in left field but I have been there before. Some  
vhf/uhf yagis don't have the longest element as the reflector; the d.e. is  
actually the longest element. Could this be the case with your antenna?
 
Also, an error of 1/16" at 440MHz is only about 1/2 of a percent. The error 
 is not present on all of the elements so the effect will be very minor  
differences of some of the lobes as seen on a computer generated pattern plot. 
 These lobes are already well suppressed so minor changes are basically  
irrelevant. They may even be improved.
 
You mentioned the elements are longer than expected. If you are truly  
concerned you could trim them with a file or better yet a belt sander.If  you do 
that, the chamfered ends should be restored as that also has an effect on  
the electrical length.
 
This sounds like a non-problem.

Patrick,
There is no possibility of being wrong measuring these.  Used an
adjustable (tongue) square to get a correct length  measurement.
