antennas vs coax cable spacing

When picking out antenna mounting locations, are the separation requirements for spacing for the physical antenna or does it apply to the coaxial cable that carries the signal as well? Looks like basically every antenna hates the other one, and they all need to be about 3 feet apart.

This might be an obvious question, but I'm a little confused. Obviously a legacy radio stack would have the GPS, COM, NAV, XPDR, etc. all on top of each other and presumably the coax wires would touch and violate the spacing requirements.

I'm finalizing the antenna locations, and have them all separated, but the coax cables will run through the same holes in the spar. Is that a problem?

Thanks

Chris,
The requirements are for the antennas. The coax/signal runs are generally fine to be grouped together. Just make sure you use the coax cable type required by the manufacturer.

Awesome.

Thanks Ian for the quick response.

It made sense that it's the antenna separation that matters, not the coax - but I learn something new each time I look at avionics.
