Do you need to have one attached to each device (tv's, computer) or have only one attached to where the cable line comes into the house?

You will need just one for the cable connection getting into your house (this has to be connected between the cable line and the junction/splitter box).

You only need one of these, attached to the main cable that comes into your house. That will stop any electrical surge that may come through the cable itself. It doesn't function like a "ground" for everything, though... The power cord of each device (TV, computer, etc.) will still need to be plugged into a wall outlet or power strip that's equipped with surge protection in order to stop surges that may come through the regular house wiring.

You only need one for the Hopper. This will allow all the devices to access OTA channels

I believe it needs to be after the splitter. I currently have it between the cable box and the splitter (TV-cable box-isolator-splitter-wall). Connected directly to cable box with a connector. I think I remember testing it between the wall and splitter and it didn't work.

No you won't need one.If you plug a cable in the lan port,you can hook that to your PC.

no, but you will be better off using just one. One connection fewer conflicts.

The outlet billing is controlled per addressable device (cable card), not per tv. This counts as one device even though the cablecard (and ceton tuner) supports up to six streams (actual tv's)

Yes, you will need one for each device you hook up. I have one at the modem two more. One for each of two tv's. Works great.

Actually - either one - but no need for both - I believe the cables need to be plugged in for the unit to turn on also.

Not absolutely required, but advisable. I did it with one monitor by repeatedly (maybe 3 times) moving it from OLD to NEW computer, so it can be done with one. Be careful to follow the instructions for what to do on each computer in which sequence, including waiting to attach the cord.

Both. Use a splitter. I have a monitor on top of the DVR and a cable running to my T.V. in the family room

You need one per TV. Splitting the feed will reduce signal strength to each TV set, and you won't receive all of the channels that you should.

No you need 2 units, one for the router and one for the modem, then multiple ethernet cables ti connect it all

Yes, it is designed to protect the coaxial cabel system to any and all devices that are conected. Installed at point coaxial cabel enteres the house so that the entire coaxial system in the house is protected. Any tv or computer conected to the coaxial system beyond the instalation point would be protected.

You will need at least one HDMI cable for connecting your cable box and a second one if you are connecting a Roku or similar item.

This is a single either for Positive or negative connection. You need two cables.

Absolutely!!!...I actually have two separate single gang boxes mounted between...one for power to tv and power to cable box and one for cable coax connection...works perfect!
