I had a dish network sat dish and outside over the air tv antenna mounted to a   
   tower until a storm blew through recently and blew the tower over. The person   
   that installed the dish installed a coax grounding block near the point of   
   entrance of the coax    
   into the house. Both the over the air coax as well as the sat coax were   
   connected to this block. A ground wire ran from this block about 12 inches to   
   a power cut off box for my outside ac condenser. (Is this legal/proper?)   
      
   Anyway, I never had any problems out of the system. Years ago I had a ground   
   rod at the tower and had nothing but problems with lightening strikes. When   
   the person grounded it to the ac unit thus connecting it to house ground, I   
   never had a problem.   
      
   The sat was re installed near its original location except to the eave of the   
   house. I have been thinking of installing my new antenna and rotor on my vinyl   
   chimney. Currently the chimney is not used, I don't even have gas logs   
   although some day I might.    
      
   I guess my question is, can I install this set up on my chimney, running my   
   new coax down the side of the house to a new grounding coax block, then   
   running a ground wire from the coax block into the crawlspace to a junction   
   box that is already in the    
   crawlspace? (Thus grounding the coax to the house ground).   
      
   Also, I noticed that even before, the installer grounded my coax for both the   
   tv antenna and the sat dish but the masts for each were not connected to any   
   ground. Should they be?   
      
   I appreciate any advice.
