Grounding

[MB33]

HD OTA Team:
I'm running a ground wire from my coax spliter and attaching it to the ground wire coming from the antenna mast leading to the rod buried in the ground....i.e.

Mast>>Mast wire>>intersection of coax ground wire and mast wire>>grounding rod

Is this set up OK or do I need separate ground wires running from each item all the way to the grounding rod?

separate wires aren't needed, but i would recommend all ground wires be atleast 10 gauge, and make sure that electric is grounded to the same ground rod. The ideal situation is all utilities and your antenna share the one ground.

Antenna LAW

NEC National Electrical code Dictates that any antenna or Dish must be grounded to the same ground as the electrical service, its the law!!!

Dodge,
We must be mistaken. I reported a NLOS to DSI because the building ground was very far away from a cx second floor apartment and there was no landlord permission to run wire or locate a dish outside the tennan's rented space.

Dsi sent another tech who got the job activated. He used magic ground source.

My antenna and coax ground block are about 60' from my power ground. I have a #6 run from the power ground to another ground rod at the coax ground location. There I have a #10 from ground block and a #6 from the ota bonded to the #6 at the 2nd ground rod. When in doubt, bond the hell out of it.

You did the right thing better to walk off a job than to be responsible for an ungrounded dish install and have something happen and lose your ass!!!

A little cornfused!!!!

According to the NEC, mast/mount grounding is to be done directly with no splices or connections between the mast/mount and the ground rod.

Yet, in the picture above it clearly shows the mast ground going to the ground block first, a run to the ground rod, then onto the whole house ground. What gives???

Or, is this simply a matter of "BONDING" the antenna ground to the whole house ground?

From the 2002 code the above picture looks correct. Has anyone seen the latest code book for any changes?

Grounding for RF:
Most people do not know how very important ground is when using any coaxial cable. You should never ever cut any coaxial cable just to put in a grounding block!. Coaxial cable works best grounded at both ends.
