[TowerTalk] Adding an RF choke

I used a small diameter 75 ohm PTFE coax for the choke and shortened the
feedline accordingly.

I wonder of a ground mounted vertical with buried coax really needs a choke?

Building a set of phased verticals and the phasing lines are critical (of
course) so my question here:  by adding 18 inches of cable length (choke
length) does the phasing line length need to be shortened by 18 inches?  

Or should I consider the choke as part of the antenna and not make any
adjustments?
