Installation issues due to strict grounding requirements

  • Question
  • Updated 8 months ago
Does the satellite dish really have to be grounded? If so, what are the requirements? An installation technician told us the dish would have to be grounded to a water main, as there were no other good options at our site, and so the dish would have to be installed either on the front of our house or on a pole on the side with ugly green and white wires running across and down our brown exterior walls -- not an acceptable option. We were told it could not be located where we wanted it installed, on the opposite side of the house with a clear view to the south, and closer to where the line would go inside for the modem. Are the grounding and other installation rules really so strict? Aren't there other options for grounding a dish so you can locate it in an acceptable spot?

Hello EFT,
We do have a very strict standard for grounding and installation. Largely, as you can probably imagine, this is for liability purposes but also for quality of service. If you would like to, I can have you email us your contact information at exedelistens@viasat.com and I can set up something where we can possibly send a tech to look over all the options for this at your location.

Thank you.  I appreciate the prompt response.  We will call to arrange a second site visit with a different installer, as the first installer couldn't find a solution that was satisfactory to us, probably in part because it was late in the day and there wasn't an obvious, easy solution. If I have more questions, is it better to ask them on this forum, or via the email in your message?

Yes the dish needs to be grounded but I never heard anything about needing to be grounded to a water main. My installation just has the wire inside PVC and going to some rebar underground.

Correct me if I'm wrong, but in order to be grounded, the ground wire just needs to go to some metal to discharge-- this is why ground wires inside outlets often terminate at a screw.

Does the dish need some sort of special grounding other than that?

This article explains why satellites should be grounded:

The general idea is to try to prevent equipment from being fried or people from being electrocuted.

Just carious...if the dish is pole mounted why does it need a ground wire? Would the metal pole its self not be the groud? After all a ground is a metal rod or something in the ground.

The pole should be bonded to the residence's electrical ground otherwise there's a potential for introducing ground loop interference with two separate grounds.

Many years ago while on vacation in the Caribbean a ham radio operator I knew down there asked me for some advice since he was having interference problems. In the Caribbean the attitude was if one is better then more than one should be optimal. Looking things over he had three or four different ground rods for different equipment... by the time I left he had limited it to a single ground and viola... no interference. All was well, don't stop the carnival but didn't matter for most except him since everyone else tended to cut the ground wire at their outlets and switches -  yee haw!

The only other advice I offered him was to not stand directly over the ground rod if the dormant volcano became active...

At least that's my understanding of grounding but I'm not an electrician nor do I play one on the internet.

Thanks labs I didn't think about that. I should have sense dad is an electrical engineer but sometimes you forget about things

Most of us think of grounding only in terms of safety and not the technical issues it addresses ...  

FWIW and revisiting the original poster's question, I vaguely recall that the ground should also be at/near the satellite cable point of entry to the residence for some technical reason (path of least resistance I guess) . The electrical ground is generally near the electrical meter - this could also impact dish placement and cable routing requirements I'd guess - all I know is my cable enters the house right below the electrical meter and within three feet of the ground rod.

You guys are lucky! My installer said I have to buy my own pvc pipe to bury the line and he wouldn't do it! He left my cable on the ground going over my gravel driveway to be destroyed when ran over! I just recently buried it myself after having to buy a 75ft cable to replace the one my neighbor ran over! I also changed to ground wire from being on the pole for the dish to grounding it to a rebar staked in the ground. Which actually made my signal better somehow. Seriously changing service once contract is up! Too many issues with customer service and loss of service almost everyday! When it's good it's good but the bad happens more often. Oh yeah they destroyed my siding on my house drilling into it which I didn't give permission to do! I ran it under!

The tech purposmy tanked your install because you sound to finicky.... in your own post he gave you 2 options...but you dont like yucky wires yadda yadda. Once he realised you were not definantky going to let him earn money, he tanked your job to move on to a job he coukd get done and earn money.


We get paid per job........if you sent the installer away, you "stole" from him. Its just a satellite dish.... you want service or not?


All this just my opinion

Also...about grounding...... there are a few options we can use to ground........ cold water pipe being on bottom of list......as long as there is a better choice. But im nkt going to run wire from one side to the other to ground to a elec panel....

This is the kind of attitude that causes companies to go out of businesses and people to get irate with a company.  I don't care if you are a contractor or not. It's the customers house that they are paying for with there hard earned money and it is your service that they are wanting. The customer is ALWAYS wright!!!!   If you don't like your job find one that you do.

Haven't seen Kaotic around here in well over a year and that one was two years ago - he was likely chased away with his surly attitude which I never cared for - but maybe he's going under a different name now and that will serve as a reminder ;)

P.S. Has anyone seen A Everret Neuman??? Duck you out there??? You on the line??? My rock is vacant...
