I've just received a copy of plans Section 31B. On page 3 it tells us to route the comms antenna and the transponder antenna cables through separate snap bushings in the panel base. The original Section 31 didn't state that, though looking back at the diagrams it did imply that!
For some reason that I can't recall, I ran both cables through the larger snap bushing. Can anyone shed any light on why it's important to have them in separate bushings? Is it to keep them apart to prevent interference? They get together quite closely once over the rudder pedals and into the tunnel.
If it is going to cause electrical interference, I will pull one of the harnesses out and reroute one of the cables, but I'd rather not go to all that effort if it's not a significant problem.
Any thoughts?
