RV10 tailcone ELT and Magnetometer question

B

I'm New Here
I am building out my tailcone and received Quickbuild wing and fuse two weeks ago. I have been trying to settle on a rough draft plan for locating antennas and magnetometer.

Equipment I will be working with (IFR RV 10):

GPS: Garmin GA-35 WAAS
Comm 1: Comant CI-122
Comm 2: Comant CI-122
Transponder / ADS-B: Comant CI-105
Nav 1 (VOR/LOC/GS): Bob Archer (hidden inside right fiberglass wingtip)
Garmin GHA-15
ELT: Standard 406 MHz whip
GMU-22
FlyLED position lights and leading edge landing lights on each wing.

I have read the discussions on here and have been studying the install manuals. The main question I have is regarding the GMU-22 and ELT antenna.

I am planning to follow manufacturer instructions with the ELT location (top of tailcone, near vertical stabilizer). I would like to install the magnetometer on the steins fuse mount on the f1008 rib in the tailcone.

Has anyone successfully passed an interference test in that configuration?

I think I have a handle on all the other options / requirements.

Any guidance appreciated!
 
I have my ELT antenna on top of the tailcone and a GMU 44 but it passed without issue and has worked flawlessly for 11years.1779325582493.jpeg

The magnetometer (either GMU-11 or 22) in a RV-10 is certainly better positioned in the tailcone. No issues, works well. Easily passes the magnetometer interference test. Wingtip also ok it seems.

Great, that simplifies that.

Do either of you have a remote transponder with the antenna back there? Seems like I should be able to fit both comm antennas and the transponder on the fuse without interfering with the GHA15 cone (behind the baggage bulkhead), but considering my options :)

My comm antennas are on the bottom of the fuselage forward and transponder antenna also fuselage rear. I don't have a GHA15.
 
My remote transponder is on a repurposed Van’s GRT AHRS shelf next to and slightly aft of the Battery on the left. The transponder antenna is on the right side of the battery on the bottom of the tailcone. My #1 Com antenna is on top of the tailcone right behind the baggage bulkhead (the transition between the tailcone and the cabin top and immediately above the battery). I extended the ground plane onto the cabin top with 3 runs of copper foil tape. Com #2 antenna is on the bottom of the right wing under the wing walk area.

My magnetometer is on a purpose built shelf, high (tied to the two top longerons), forward of the first bulkhead behind the baggage bulkhead. My ELT antenna is tucked in the space behind the passenger door trim, with the ELT unit on the tail cone wall just behind the baggage bulkhead. I have two bent whip com antennas on the bottom just aft of the wings. The transponder antenna is bottom about mid tail cone almost directly below the magnetometer. All of my GPS antennas are in the overhead except one on the glareshield.
Everything works perfectly with no interference. Com reception on the ground and in the air has been exceptional.
