Default Becker Transponder Garmin GDL-82

Has anyone installed a GDL-82 with a Becker Transponder ATC-4401-1-175?
Did it work for you?
Did you get error code (on the becker) E10?
How did you fix it thanks.
The transponder works fine, until you power up the -82 then it throw a code.

Default Compatible

I installed a GDL-82 with my Becker 4401. I had no issues. Have you found out what the error code means?

Default Bus

Mine is setup so the GDL-82 is on when I turn on the avionics bus. So itís already on when the transponder is turned on.

Default E10

Best I can tell Ground Plane issue.
Did you use one of the recommended transponder antennas?
I'm using the single pole ones, going to try again then may order a new ant if it stills broke.
Thanks

Default Antenna

I looked up the error code. It says itís an antenna problem. So it sounds like the transponder doesnít like something in the cable or antenna. Maybe double check the proper connections for the transponder and antenna output.

I used the blade antenna already installed. I just ran the RG-400 to the GDL-82 and put on a new connector. I donít know what the model number is for the antenna.

Default coax

Well, we "think" its fixed need to do the flight test in a few days.
What stop the error code was adding to the length of the RG400 coax (about 18" long) from the transponder to the GDL82. Replaced with about 6' of RG58 with a BNC male adapter to connect the two. Tried all different combos but this was the only one to work. Its now about 6' total length, RG400/connector/RG58. So that's the story now, time will tell......

Default Mounting

Mine is mounted on a center console between the rudder pedals. The GPS antenna is on the glare shield of my tip-up canopy.
