Hmmmm . . . okay. Do the backup instruments have
dedicated input connections for backup power?
Do they feature or do you plan to have a
pilot operated power switch for these
devices?

Hi Guys (Bob)
I've gone for the simple rod com antenna (http://www.aircraftspruce.com/catalog/avpages/stainlessantenna.php) having heard good reports (compared to the much more Comant types) the connection is a simple bolt - I presume PIDG connectors (both centre core and shield) keep them as short as possible, any other thoughts guys ?
Also: one more time - how close/distance from the transponder aerial should the
two be ?
Regards
John RV9a

That will work. Cessna produced thousands
of airplanes with that 'style' vhf comm
antenna. Is this a metal airplane? If
not, don't forget the radials.

As far as practical . . . but I've seen
installations as short as 12" apart
where owners reported no observable
effects.

Hi Bob
It's a Van's RV9a (all metal), so a decent mounting backing/plate will suffi
ce - yes

| Subject: | ADS-B Antenna Located Next To EMS |
Hi all,
I have a velocity aircraft and therefore space is a little tight so I am
considering mounting my Dynon Skyview EMS module directly onto the ground
plane of my ADS-B antenna.
If I did this, could there be some sort of interference or noise from the
ADS-B antenna transmission and the unshielded sensor wires of the EMS unit?
THANKS!!!
Bill Hunter

I wouldn't expect a problem, but would try to get an inch or two of
separation to ensure no interference.
