Although code requires they be separate, for a DIYer if it won't be
inspected, you can do anything.
My preference is, if it will be carrying power (120 VAC) I'd run them
separate mainly because of lightening and possible common mode noise
pick up. (RF into the AC, or noise into the coax?) That you won't know
without trying.
I'd be uncomfortable with a 200' run of intimately coupled control,
power, and RF cables.
I even run my CAT-5 Gigabit network separate, which is probably a good
thing. Lightening got into the network last Summer and took out a
router, 8 port switch, 3 NICs and one motherboard. It melted an RG45
into the UPS and welded the pins together, but no damage to the rig down
stream although I'll never be able to use the network protection in that
UPS again.
What would your insurance Co say if you had an expensive lightening strike?
73 es good luck

Hello,
I have a Rohn 25 up about 85' located about 200' from my garage radio room. Is
there some compelling reason why I shouldn't run bury flex coax, rotor cable and
outdoor 12-2 w gnd through a 2" plastic pipe (already buried) between the
tower and my shack?
Bill Fairbanks, N9ela
