G’day all,

I bought a Comant CI-121 NAV/COM/GS Antenna (V dipole) to install on my VS but  I have discovered that it won’t fit.

The diameter of the mounting base is 2.5 inches and that will not fit into the Fibreglass Fairing on top of the VS.

Which V dipoles have other people used on their VS? 

 

Cheers

Hi John,



I realize you posted about this a few months old, but I thought I'd comment on your VOR antenna mounting conundrum.  You called out a "CI-121 Nav/COM/GS", but I think you really meant something like a CI-158C which is a Di-pole VOR/GS/Loc antenna.  The CI-121 is a fiberglass COM antenna only.



Here is the Cheif web page on NAV/GS/Loc antennas:

In any case, I mounted a CI-158C in the fin of my RV-8 and it works very nicely there.  Here are some pictures of the installation:
