All,

Thanks for the replies. One clarification; I meant "ground rod" in 5.)
above, NOT "lightning rod". It should read:

5.) Finally, consider an amateur antenna on a pole, located some
distance from the service entrance of the house. Let's say there is a
copper cold water pipe right at the service entrance. Is it wise to
place a ground rod (or rods) right under the antenna, place an
arrestor on the coax there and then another arrestor where the coax
enters at the service entrance? Is a ground wire needed between the
remote ground rod and the cold water pipe?

Thanks,

-JJ
