[TowerTalk] Determining coax length?

[Rich Hallman - N7TR]

I am stacking several mono banders with a stackmatch II.    I have the antennas mounted on the towers, but the coax feedlines are different lengths right now.    The Stackmatch wants coax lengths to both antennas to be the same length, but I'm unable to physically measure to the end of the feedpoints on the boom.  All coax is the same (RF Davis Buryflex)

Questions:

1)      How critical are the coax lengths to the stackmatch from each stacked antenna?
2)      What tools can I use to determine the length of coax to each antenna?  (AIM 4170, MFJ, etc?)  and how do you determine equal lengths?

Thanks...
Rich
