Tap that will prevent back feeding

Markdub2000

I have a upc point in the attic room, can I take the tv output of this and combine it with a head end unit to add a further 16 channels to the existing service in the house through an ordinary F-connector type tap

or do I need to add an additional filter to stop back feed into the network?

Officially for each additional TV point you need to get UPC to install it and pay extra per month.

Unoficially any TV splitter will split the signal in two. However you are also halfing the signal to each TV. This means for analogue more snowy channels, for digital more freezing etc.

Also if you call UPC and they see it, they will remove it and charge you for the trouble. They only guarantee a good enough signal for one TV, per UPC outlet.

Ideally you would get a proper outlet per TV. If you pay for a second outlet I think a basic (grey) digital box comes with it, which gives slightly more than the 17 channels, depending on your subscriptions.

UPC use lots of frequencies, some for analogue TV, some for digital TV, some for internet. You would need to use a spectrum analyser to find gaps (probably up near the top end of UHF) to place your CCTV channels.

So what channels have you added to UPC's lineup?

You should pipe it back down the cable and let everyone else get them free too. Only kidding. But I did hear of "pirate" cable TV stations where people put a modulator before a UPC amp and created their own channel on UPC, not that I would recommend it.

UPC kitted out the house, the feed comes in through the side of the house up to the attic where it comes into a upc fitted tap - they have those lovely heavy duty F-connectors, from there it goes into every room in the house into upc outlets.

I don't want additional boxes and wiring in each of the rooms, just a few extra channels, its easy enough to add with a booster to prevent back feed into upc's network and boost the upc signal with the rest to get it up on a par with the head end...

plenty of hotels have similar systems...
