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.

Mine is to a 4' into the ground metal rod and a stranded green wire to
the rod from the shield mounting clamp.
Putting the ground to the small box, the high voltage could jump in
the box to the power legs and into the house..... Oh not again....

Best into the ground. Copper coated steel rod. Hardware store,
electrical supply, Lowes, Home Depot, etc.

Mine is an 8' copper plated rod driven 7'8" into the rocky ! ground .
It's directly below the new meter base , and all grounds will be thru the
rod when construction is finished . Right now , everything -including phone
and sat - is grounded at the base of the temp power pole next to the camper
