Running coax in same conduit at 120v

[Flint Ridge]

I'm looking to make some antenna/tower upgrades over the next month and in the process I am faced with the question of running separate conduit or run it in the same. What are the interference potentials of doing this? I'm trying to improve reception not introduce a new issue. RG11 shielded cable and a feed line for power, at the tower.

Thanks!

Interference shouldn't be a problem but the National Electrical Code doesn't permit sharing power more than 30 volts and signal in the same conduits.

Ok, good point. I'll bring power from the other direction, which technically is a much shorter run and keep them separate, in case something goes "wrong", I would not want that kind of power.

Thanks
