Per bud--:
I agree. There should also be a ground block where the coax enters the
house. That allows the coax shield to be earthed. That connection, in
particular, plus the ground wire from the TV antenna, should connect to
the earthing system near the service panel. ...

That requires a short wire
from entry protectors to a common connection point on the earthing
system. The distance from the service N-G bond to the common connection
point also has to be short.

Is there a conflict there for a TV antenna mounted on the North
end of the house with coax running down the North wall and
entering the crawl space there - and a service panel on the
opposite end of the house?
