[TowerTalk] Running Cables - Shack to Tower

[Roger (K8RI) on TT]

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
