Replacing com antennas

I can now partially answer my own question since I've received the antennas
from Spruce. The only thing in the box is the antenna and a base gasket.
I'll need to purchase new nuts and screws and evidently no 'conductive
grease' is needed.

I've ordered a pair of CI-291 Comant com antennas to replace the well worn
antennas on my Archer. Besides removing any oxidation where the aluminum
base contacts the aircraft and making sure the coax connector is clean and
serviceable and the mechanical connection robust, are there other mounting
considerations? For instance, is a conductive grease used between the
antenna base and the aluminum panel? Does Comant include any extra
goodies for the installation?

The 3 mounting holes in the new antennas are in exact alignment with the
old antennas. The interesting part will be backing the spinning nuts in
the tail cone while removing the outside screws. I should be able to
capture the coax with nylon ties to keep them from falling back into the
fuselage while preparing to mount the new antennas.
