RG400 coax close to #2 AWG Batt cable

[Dorfie]

How bad is it to run the RG400 in close proximity (<2") or directly along the AWG2 batt. cable? VHF com antenna, GPS antennas. Will it be a problem drilling an extra hole in the F-1004C and D center section bulkheads? I am running out of space on the sides using the pre-drilled holes.
This is in RV10.
Thanks.

I personally would not worry about it. Main DC buss should be quiet.
The coax is good quality and radiates very little if at all.

In theory, the electric field in a coax is contained between the center conductor and shield so it shouldn't matter.

Thanks guys.
