hi Andrew

Please do ya best to answer the following barrage of questions and I may 
be able to assist :

but all questions need to be answered to solve the crossword...

1) what is the whip.

2) where is it located, precisely

3) does the ground on the base of the whi[ measure 0 ohms to the chassis ?

4) how long RG58 lead in ?

5) Is the radio grounded via a local ground short strap/thick wire to 
earth bolt or only its negative power lead ?

6) does it dip below 2:1 VSWR anywhere when you sweep it with a VNA ?

7) With the VNA, is the VNA grounded, or floating on the end of the  coax?

8) With the VNA, if floating, does the VNA indicated sweep/match change 
if you ground the outer of the VNA coax connector to a local ground like 
ground bolt ona  door hinge etc
