WOLF,Wolffpack said:You may want to run to Lowes or Home Depot and grab grounding rod and hammer that into the ground right by your tripod. The installer can attach the ground wire to that. Just make sure you inspect it before they leave. Also make sure they install grounding blocks for the coax. Here's a pic of my old DirecWay install with the grounding block. This is what the last DTV installer that came out Friday failed to do on mine.
The dish /mast ground should be 17 awg > usually this is with a messenger wire that IS already attached to the cble. > Purpose = removal and a place for the STATIC electricity to be discharged Which reduces "the draw" of a lightning strike. (from dish mast to ground blk)
THE COAX gr wire should be AT least #10 awg. (from gr blk to NEC approved gr location/source)
So even that pic of the D-way is incorrect grounding.
THose ground rds mentioned(drove in the ground) are NOT legal grounds UNLESS they are 8 ft ground rods.
ALSO.. depending on how the NEC is read AND who you ask opinions "some say" each gr wire needs to be independently ran to the gr source.
Personally on residential installs i use the ground blk and the doulble screws per the blk to ground the mast and then a #10 wire from the gr blk to the proper gr source.
ALWAYS provide drip loops (circles w/ the coax) at each end of the gr blk also.
On the Big REAL jobs i run 2 seperate wire (mast and coax gr) to an appropriate NEC gr source. Why ya wonder?.. Its not because i BELIEVE the necessity and interpretation of the NEC... BUT .. simply due to different inspectors may have a diff interpretation and its My safe way out knowingly to adhere to any inspection and prevent that word/paper of "punch list" (wink)

Heres is a picture of some proper grounding.. (this one is a residential install that for some reason (lol) i ran 2 sep wires (mast & coax) to the MAIN gr souce > (notice BOTH copper ground lugs and the drip loops)..
You see something resembling this at your residence then you ARE grounded properly. You dont.. well the so called wanna be's that did your install Just violated & Neglicated the NATIONAL NEC CODE not to mention seperate local codes per local/DMA.
(PS.. wOLF> GO LOOK @ that "AT-9 needs help" thread if ya want to see some REAL grounding. I posted a pic there of a commercial ground in a EQ rm.)
