You can run the twin line close to a coax or any metallic object for a
short distant. I would suggest you use some distant, even so little, for this
short run. It's a matter of what capacitance the individual wires "sees" as
well as what magnetic field from the twin line can interact with close
objects.

Subj: [TowerTalk] 450 ohm feedline and coax
HI All
I've seen that you should keep the 450 ohm twinlead at leas the width of
the cable away from anything metallic. Does that include coax cable? I
want to run some twinlead out to an antenna and where it would come into
the shack is a coax cable and it would be laying right on top of it.
Just wonder it that would cause any problems. 73 and Marry Christmas.
