This is correct however you can also use a signal generator
(or even your TX) and a voltmeter with an RF probe.

At 20M, getting them within a foot of each other will be
fine and with a tape measure you can get within an inch or

you can use a TDR to make sure that they are the same
electrical length which is really what you want. If they
are off the same reel of cable, physical length will be
close enough in my experience. There are many other sources
of error in stacking that will diminish the effect of
feedline length.

Subject: [TowerTalk] Cable Length???
Hello All,
I am planning a 2 stack for 20 meters.
Is there an easy way to measure the lengths
of coax cable in order to get them the exact
same length???
Thanks in advance for any suggestions.
73, Ted K2QMF
