[TowerTalk] Running Cables - Shack to Tower

[J. Hunt]

If a person took a lightning strike and if determined the homeowner or other party installed an electrical device not per NEC, the insurance company reserves the right on not paying damages.
If determined a contractor installed something not per code, they are liable.

As for the the DIYer, if ever inspected - questions would be raised.  Permits, city inspections ......  Some insurance companies are getting more picky and inquisitive on proper installation.  None compliance = non payment.
 
If a structure fire resulted, the Fire Marshall looks everywhere / everything.
It is NOT worth the risk.

I have taken many lightning strikes over the years.  Usually nothing happens.  A few times I experienced destroyed antennas and the hardcore lightning protection mounted on my tower protects the feedlines and anything below.  
This mess is integrated with a  Halo Ground system.
Everything meets / exceeds NEC and city codes.


Thanks N 73,
James Hunt

 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
