Default Decoupling coax transmission line


I have 50ft of 9914f feeding a ground mounted 4-BTV. After a little tweaking
I have advertised swr across the 4 bands. (1.6:1 or less). The 4-BTV
instructions recommend a coaxial choke for "de-coupling the transmission
line".

I would like to be able to do some kind of analysis to see if I really need
to do this or not. Also with buried coax if I did so would the coax choke
get buried too? They (Hustler) recommend 10 turns of coax on a 6 inch form.
I am really pleased with the station so far ( about a week old!) and cannot
see any symptoms that I need this choke. I have a 6ft ground rod about 2 ft
from the rig and all is well best I can tell. What would some of the
symptoms be if I needed this rf choke?

TY
