Garmin 796 External Antenna

[JetSet1967]

Does garmin make a antenna that you can mount on the exterior of the aircraft that will run both the gps and the xm weather?

[Jerry 5TJ]

Yes, there are some.

Here's one http://www.cobham.com/media/7576/ci%20401-460%20data%20sheet.pdf

It is about $650. Note that this is just an antenna, and many portable units like the Garmin Aera series use a separate XM antenna/receiver module.

I installed an exterior GPS antenna for my 696, but the XM runs off of the glareshield standard antenna. Is desire just to "clean-up" the glare shield? I have never had an issue with connection to XM.

I have a Garmin 796 that I use a glareshield XM antenna with that works perfectly, and I use the internal GPS antenna on the 796, rather than the glareshield GPS antenna. I do not find any significant difference in signal strength, and the glareshield GPS antenna fitting into the 796 distorts the AirGizmo panel mount to the extent that it is difficult to set correctly into AirGizmo's socket, and makes taking the 798 out and in more difficult. Since I am on a 28 day Jeppesen update cycle for the 796, it was a pleasant surprise to find that I don't need the glareshield GPS antenna (or external antenna, of which I already have too many - GTN750, 430w, and a combination GPS/406 ELT).

I would like to install a external antenna just to clean up the cockpit.

I have an external GPS antenna, but the XM is on the glare shield... which in a C is very little space to work with.  When I had my avoinics upgraded, they at least cleaned up the XM antenna so it doesn't look like a mess with the cables hanging in the cockpit.  FWIW.

Has anyone put the glare shield antenna under the glare shield?

Not in a plane, but I have mounted a gps antenna under the dashboard on a car. Signal is fine, can't notice any reduction in strength. I imagine it would work fine.

I've had my XM antenna under my glare shield for years. Never a problem.

Guess that's why I never noticed one

I connected my Aera 500 to the leftover Northstar GPS antenna and it works great, 12 satellites, full bars at all times.  I connected it to the BNC cable from the old GPS with a BNC-MCX adapter from Amazon.  12$
