Grounding satellite cables? (1 Viewer)

[DavePL]

Some questions...

Is it necessary to ground each cable run from my sat dish?

And do those grounding blocks degrade the signal at all?

Also... I've got a Terk M58 multiswitch. I need to feed 2 STB's from my antenna in the attic. Would I be better off using a good splitter on the antenna cable and running separate lines to each box, or just let the Terk handle it?

Thanks

They do degrade the signal. You should have no more than 3 connections between the LNB and the reciever. Most splitters are not rated for the frequency range in sat

Thanks Grant.

Maybe I'll try one with a ground block and one without,see if it makes a big differnce and go from there.

I don’t expect you’ll see a difference. A grounding block is a straight-through connection, like a coupler. It doesn’t reduce or degrade the signal. If it does, you already had a worse problem - like a faulty cable, too many splits, poor signal strength, etc.

With STB's, each unit provides voltage to the LNB. If you are using a splitter, one of the connections needs to be blocking the voltage to the dish. Or, you should have a dish that has 2 LNBs on it. Hopefully, the Terk unit takes care of this for you.

Wayne and Lee,

Thanks.

I'm hooking everything up this weekend so I'll go ahead and use the ground blocks.

Thanks to all for the responses. I'm sure I'll have more questions once I start trying to hook everything up.
