I have researched this here and I do have conflicts with the INFO from other posters. I think a ground is a ground whether its 15' or 30' away. But I am asking you to help clarify grounding protocol. I want to make sure I am installing this new setup safely. I am probably dangerous because I used to buy the old single lnb 18 inch dish and thought I was an installer.
1. I just purchased a new SWM with a 3LNB slimline dish to replace my brothers old setup.
2. The old ground system was for a 4 cable-port SL5 and it was connected at least 12 years ago and is almost totally gone. Cables dry rotting. etc.
A. I ran new RG6 cable to the new slimline dish and SL3.
B. I powered the new Power Inverter up along with the IRD to the HR24 via 4way splitter. I have a green label 8 way, but we don't need it and I read your signal loss post earlier.
I stated the above to ask this question!
What grounding options should I implement?
What is the best option for completing that task?
If it was yours how would you handle it?
You just want me to get in trouble don't you?
Grounding varies by local jurisdiction, since it's covered by local code.
[hope that's enough legal disclaimer].
While a "ground is a ground", how much resistance a connection has to ground will vary.
Copper wire has resistance [in a few inches] that can be measured with a very good meter.
The difference between 15' and 30', might be overcome to some degree by using a larger gauge wire.
Another thing is what are you trying to "ground"?
Static buildup and normal house power, will be grounded through reasonable size wire and close to the house ground point. [vague enough? :lol:]
Now if you're asking about a lightning strike, it's a whole other problem.
In this case I would have the ground before the coax comes into the house, and have the ground wire/rod has large and as close as possible.
If this means a second ground rod, then it has to be connected [large wire again] to the house ground point/rod.
"Electrically" this will look something like this:http://www.dbstalk.c...=1&d=1298403866
And you want to keep all the resistance as low as possible.
Even this is only going to give you "the best chance" of limiting any damage.
