Dish grounding

[Captain Tom]

I have a Dish 500 and looking at birds 119 &110 and receiving over 500 channels I also set up 2 friends with singel LNBs looking at 119 and they are bouth getting over 200 channels. None of theses dishes are grounded should they be? And what's the advantage? Also due you ground the dish or install a ground block on the cable splice?

Take a look at this post on grounding. Great advice from SystemDude...

first reason is if dish gets hit by lighting it does not fry your stb
second helps with fluctuating power sent from stb to switch and/or lnb
third i have dish grounded and a ground block on my cable but that is just my choice

If your dish is installed on a post in the ground (mine is encased in concrete), then you're fine. The dish is literally grounded as best as it can be. If it's on the roof, or mounted above ground, running an additional ground wire (as listed below) will be helpful to you.
If the run from your dish to your receiver is exceptionally long, you could run a bare wire from your dish and ground it to your STB. That will guarantee (almost) that your STB and dish are at the same potential. Which will reduce any potential transient voltage surges...like lightning. Your STB is grounded via your electrical panel, which is grounded (typically) outside your house. So everything is at the same potential.

Thank's Guys! I guess that answers that I will install grounds.

Once you've ran the grounds, let us know your results. There might be another issue we can resolve.
