Topband: electrical wavelength

[HAROLD SMITH JR]

Hello Bob, 

I have used the published velocity factors for years. 
I made a 4:1 balan for my Telrex 20M546 a few years ago with RG14 coax. After I 
cut it, I checked it 

with my GDO and all was fine.

Hi it's still flooded here but I wanted to fire up one of my verticals by itself 
on 160 and feed it with a half wave of Comscope RG6 since I don't have enough 50 
ohm line to reach it. I have a AIM 4170 to cut the line with but my question to 
the group is - how much variation from published nominal velocity factors have 
you encountered in practice when cutting lines to length? How accurate do we 
need to be for 1/4 wave lines?

73 Bob
