You're correct, Steve.Â* Better knock off a millimeter or two from the
length although the length I quoted was not precise.Â* Maybe 3 mm... :-D

Happy New Year!

If it's not too much trouble, try a coax cable length of 21 11/16 inches

performance.
Dan: I'm not jumping into the real technical matters here but its pretty obvious that you're neglecting the fact that waves travel slower in coax.
