1, 2, or 4 port amps
Has anyone used an amp to boost their cable signal (especially if you've split it).
Something like this........ http://cgi.ebay.co.uk/ws/eBayISAPI.d...771700557&rd=1
How do they work? Do you have to plug them in or are they portable and just screwed on the wall ourside?

Re: 1, 2, or 4 port amps
I think AMP is just the name of them, not thier purpose. They just look like RJ45 sockets to me.

Re: 1, 2, or 4 port amps
AMP is just a brand name, those look like standard sockets.
You would have a fair bit of trouble trying to amplify a coax feed with those.

Its mentioned in the last question in this link....... http://www.dslreports.com/faq/cabletech/4.%20Splitters
I want to do the same......... I want to fit wall plates in several rooms so that they all have access to cable.

Re: 1, 2, or 4 port amps
If you only want to share an internet connection, then go wirless, its so much more easier than runnign cat5 cable through the house (trust me ive cabled several houses).
If you need high bandwith for piping large files etc around you are going to need a router to share the connection around and then, You will also need some specialist tools for cimping connector ends etc...

Doing this you may find that your broadband suddenly stops working. Why? Because your home has been found to be a source of interference and has been isolated to prevent the interference getting onto the rest of the network.
You may also find that if you're in a digital only area (they are out there) doing this won't get you anything anyway.

If you want to share cable TV around the house, you would need an amplifier/splitter for CO-AXIAL cable (not RJ-45), but, TBH, you would be better either asking NTL to install the extra sockets (which they'll probably charge for) or getting a video sender that can work with NTL remote controls as well.
If you need to share an internet connection, it's easier to get a wireless router and use a wireless network.

Re: 1, 2, or 4 port amps
Agree totally,I ahd a fault once,the guy's B/B did'nt work.When i went out,all was weel.This went on for a week or so,working ok when i was there,not working after i left!
Turned out he had a chipped box which was spilling noise onto the network.He disconnected the box before i arrived,curing the fault & reconnected it when i left,creating the fault!
Networks ended up fitting a return path noise blocker to his line as there were so many complaints!
Best bet,leave it to the proffesionals if you want it to work.

Re: 1, 2, or 4 port amps
How do you want to distibute the signal.
If you put socket in each room running off the main cable feed in, then without a set top connected to each one, it wont serve any purpose.
However, if you split the output signal from the cable box to each room, then you will be able to watch cable in each room at the same time but only what you are watching on main tv and you wont be able to change channel on the cable box from any of the other rooms. Here's what ya need to do -
Take the output from the digi box and run it into an amplifier, then take the output from the amplifier and then either run it to a 8 way tap plate and pass it round the house from there, with a cable to each room, or pass it through a series of 2/3 way splitters round the house. Depends on the lay out of the house and how you are going to run the cable as to how you do it.
As mentioned in that post that put a link to, dont use cheap splitters/tap plates as they are not worth it, you will loose a lot of signal through them. I would recomend using ones with "F" connectors on them as the connectors cant accidentally fall out.
Ya best bet to be honest is find a local friendly cable installer and offer him a drink and i am sure that he would sort it out for ya, but unless you are going to chase all the walls out and hide the cables then you are going to have cables running everywhere.
