Internet Dish Wiring

[hawkeye08]

Am I in the twilight zone or something. Once again, this is not satellite. It's line of sight to the west to a tower and it has to be on my roof to clear the tree line.

Our antennae is mounted on gable end (not on top of roof) with a 4' pipe sticking up so we clear the roof. Cable goes through hole on gable with sealing grommet. Yes, there is a dip in cable for water to drip off. If you can meet your needs attaching to peak of gable, you won't need any holes in roof (not for antennae mount or cable).

Why is that?

I think the issue is possibly lightning hitting your dish and sending the lightning right into the house.

Ours is running through a vent, we have three cables actually from the mast they all loop below the vent to prevent water from following the cables into the house. They've been like that for 5 years without any issues.

My ground wire runs down the outside of the house along the trim to an 8' ground rod (when I had outdoor TV antennae). My internet radio and antennae are plastic and the ground is provided by shielded network cable going back to my surge protector that supplies POE, no separate ground wire on current internet setup. It was professional installed by provider.

I think you are correct...addressed in the NEC I think but I recall some limited exception under old code for interior grounding of SAT equipment...use of external grounding blocks was the norm. Add to that, under current code I think EVERYTHING has to somehow come back to your common house ground. Something about "potential indifferences" that cause cows to stop giving milk. Most SAT guys will give a goofy look when you mention that and will sink their own ground rods anyway. As for the OP's plan, I try to avoid puncturing my roof. Nothing but trouble in the future.

This.

Op has the system to get Internet into his home.

His dish is just an antenna and it's pointed at a transmitter a few miles away.

These transmitters send an almost straight line signal to the receiver. Imagine a laser beam. He can't move the antenna because it has to be in a certain position like a surveyors transit.

This isn't dish in the sky sat TV.

People have made similar Internet WiFi transmitters go literally miles to a friend's house using Pringles cans to focus and aim the beam and then another to receive it. Just normal WiFi like at your house.

OP has a modern, commercial version of this system. He can't move his dish antenna unless the company moved their transmitter and then realigned it.

Fair assessment but I try to avoid roof penetrations especially in any "freeze-thaw" climate. We upgraded to HughesNet Gen4 a couple of years ago and the installer needed to move the dish (different angle). He took the old dish but did not move the mounts solely because they would leave holes. Cat5 cable isn't that big...but it's big enough...I prefer a side-wall entrance for the cable where I can add caulk from the ground if needed.

Yes, anything that compromises the roof barrier is more likely to cause problems. Much easier to move to the side under the soffit.

Guys, no one particularly likes roof penetrations. BUT his roof is already penetrated by the roof vent. There is no reason not to use that existing roof to get his cable into the house.. The only problem I see is the grounding conductor. That should not go into the house for the reasons already posted. That should go over to the side and down to the ground, and yes all the grounds should have a single ground point.
