Just wondering if you could share any lessons learned before I do
this. Zaon sells an extension kit for the antenna, and a panel mount
kit (http://www.zaon.aero/content/view/2/41/) Any antenna mounting

antenna?

Within reason. The installation manual addresses minimum spacing
between antennas.

For a carbon fuselage I would not be rushing to drill another hole to
mount the Zaon antenna. For a fiberglass fuselage you might find a
home for the antenna somewhere inside away from metal components.

The helical antenna the MRX comes with is not the same as a 1/4 wave
antenna and does not need a ground plane. If you use a traditional
transponder/DME 1/4 wave antenna you need a ground plane just like
when installing it for a transponder.

If you want to make the antenna remote you need to go to larger coax
and BNC connectors rather than the thin stuff and SMA connectors used
for the short antenna extension. More adapters and thick coax to deal
with.

Personally I'd try to avoid using a transponder antenna and do
something simple like use the small helical antenna on suction cups to
hold it some place handy near the instrument panel. Before doing
anything fly with the Zaon just on top of your panel and make sure it
works OK (reads the local transponder OK, etc.) and you are happy with
it. If you have space near the top of the panel I'd also consider
simple things like using the antenna attached to the unit and poking
though a hole in the top of the instrument panel cover/glareshield. As
long as it is clear of metal things behind the panel.
