remote transponder close to LSE boxes ok?

[Gonzo24]

I'm installing a remote GTX-32 transponder under the forward skin of my tip up 7 on the backside of the left vert rib. this area is between the subpanel and firewall. The Xponder is within a few inches of dual LSE brain boxes on the other side of the same rib. both are running RG-400 on the output sides and these will be separated.

Anybody see any issues from an interference standpoint with the Xponder and the ignition signals? Other options regarding space and associated equipment under the forward skin area are dictating this placement.

I would think since the regular transponders live happily in the radio stack without wreaking havoc when they output there wouldn't be any issues. However, since the Xponder is now going to be a close neighbor with the LSE... i wanted to toss the question out there.

Thanks...
