Bonding/ grounding your dish, tips you needs to know

[cablewithaview]

From time to time, the question comes up, "How to best ground my satellite?". I have seen some really bad installs over the years from a little unapproved 4 ft rod with aluminum wire for grounding which is a no no.

I've seen people use a ground block under a trailer and use what we (CATV & Bell) call a (bug nut) as a grounding clamp to the trailer frame, yet another no no. That clamp or bug nut is actually used to tie off lashing wire at each pole, which is used by bell and cable.

Also, NEVER under any circumstances ground to a gas meter, this is NOT a ground but an explosive situation waiting to happen.

So here is a little something about bonding and a picture of a proper way to ground your dishes:

Bonding is the way all conductive cables and equipment are continuously connected to the ground electrode.

The electric electrode is the preferred method to bond the cable.

Proper bonding and grounding is intended to equalize and limit the potential between conductive surfaces.

The ground block is the demarcation point between the inside and outside wiring.

Bonding to metal conduits or galvanized power mast pipe is accomplished with a perforated galvanized ground strap that encircles and fastens to the couduit.

Bonding to the power company decreases the difference of potential.

The bonding wire size for RG-6 cable should be no smaller than 12 gauge.

The ground wire should be as short as possible---preferably under 10 ft.




NOTE: House box is optional, I also go a step further and use grease on the threads and grommets to keep moisture out.

what does grounding do? does it dissipates electrical surge/lightning or eliminate ingress??! i have seen a lot of grounding connections but i can't barely understands how it works in the systems.. i see some households don't have it & others do have, but still they a comparable service situation.. is it better to use the grounding system inside the household premises or do it from the distribution taps????

dissipates electrical surge/lightning

Some houses did not have a ground off the meter at one time. All newer stuff for the past 25 years or so does have the ground off the meter to a rod.

You always want to bond ever so many poles so any electrical issues have a way to travel off the cable to ground. As mentioned, grounding is intended to equalize and limit the potential between conductive surfaces. So yes you must ground at the house as well for that reason.
