Hi! Fred
Mine has worked with the Garmin 320A with the antenna located on the
belly about 12" behind the enlarged baggage bay couldn't begin to tell
you what standard wire or length it is. I hope I don't pick up any
difficulty with the existing Gold Wing Strobe kit mounted about 24"
further aft but I'm holding my breath with the Garmin 328 now fitted and
the Skyflash strobe currently being fitted in identical locations.
Regards
Bob H G-PTAG

Subject: Europa-List: transponder antenna wiring
Hi All,
I'm in the midst of locating antennae and attempting to zero in on
avionics selection.
I find in the Garmin Installation Manual for their 320A transponder a
max. length for the RG-400 coax to be 8.8 feet, 12.5 feet for RG304 (a
coax which I've yet to see for sale anywhere, and 17.0 feet for "ECS
Type 311601 sold by Electronic Cable Specialists in Wisconsin (again,
a product which I haven't seen in any of our wiring discussions). This
may be a moot point as I expect to use the Narco 165 (Value Series, to
save a few bucks [unless the consensus might be that doing so would be
pennywise/pound foolish].) I can't seem to find a downloadable
installation manual for the Narco, so I'm not sure that Garmin's 8.8
foot max would still apply.
On our forum, I've only found folks using RG-400. I don't see how I
can get the distance down to an 8.8 foot run from antenna to the
panel, unless I bring the transponder antenna forward to just aft of
the baggage bay (close to strobe power supply; however, it seems many
guys have put the transponder as far aft as possible abeam the rear
bulkhead.
Any advice and counsel to this electronic neophyte would be much
appreciated...don't want to get anal, but don't want to create
problems either,
Thanks,
Fred
