Basic Satellite Dish question...

Collumbo

Does a satellite dish need a power supply?

Reason I ask is this - during some renovations in house, I had some new wiring and cabling put into the house by an electrician (a few new sockets, light switches, and 2 TV points). Once such cable connects the satellite dish to a point in the wall where I can plug the satellite into (what I call the "pipe"... not sure if that's the correct term). I connected up the TV and satellite dish, but there is no signal. The satellite is pointing to Astra; I only need some of the Free-To-Air channels.

I think that I used to have a plug permanently plugged into the wall which provided power to the satellite dish... but I could be wrong. Am I talking rubbish here? Is it possible that the electrician didn't connect the satellite to the mains (or just by using a plug) when he should have?

Is there anything else I need to check? The positioning of the satellite has not changed and it was working fine before the wiring job was done.

The dish (lnb) gets its power from the Satellite reciever, Sounds to me that you have your cabling mixed up a bit, make sure that the cable you have connected to the satellite reciever is the correct cable, what kind of wall plate did he use?? Ideally the cable from the dish should be one continuious cable from dish to box, but if a wall plate is necessary then it needs to be a F type satellite type with a screw in connection with a patch cable connected to the ""LNB IN"" on the satellite reciever (which is also a screw in type)

If you haven't got a clue what I'm talking about you will have to call in a Satellite Installer.



see proper wall plate below


And the connector for the reciever

Ahh - Just googled Wall Plate F Type Satellite and I see now. I am 99% certain he has used a standard TV socket. As I understand from googling, this won't work. There must be an F type wall plate connected to the satellite dish.

Maplin website shows a "Double Flush Mounting F Type Outlet"... As I understand it now, I need to get one of those.

Have I understood the jargon correctly?

Many thanks for your help.

just buy a couple of f connectors and a f type coupler and a short piece of coax, take off the wall plate drill a 7mm hole in it and pass the cable through, join the coax with f connectors and coupler, annother f connector on the end , job done

how to fit f connectors

There is a chance that the wallplate used by the electrician is also isolated, meaning it'll block power passing through it.

Darth Maul's suggestion is the handiest.
