Using existing coax cabling?

[FelixTCat]

We have 3 rooms with terrestrial TV, fed from a common aerial with a signal booster and coaxial cable. One is in the lounge, the second in a bedroom directly above and the third in the breakfast room at the other end of the house.

We had Sky TV installed with a quad LNB dish with 2 feeds to the lounge. The dish is mounted where other feeds could go into the roof space to area of the existing booster.

Will it be possible to connect the spare LNBs to the coax cable from (but excluding) the signal booster to provide feeds to new boxes in the bedroom and breakfast room or would I have to lay new cable throughout. I appreciate that I would have to fit new connectors.

Regards,

Felix

You can use any suitable double-screened 75 Ohm coaxial cable.

Thanks, Sam.

So, all I will need is adapters at both ends to change the standard coax connectors to the Sky type or simply fit Sky connectors to both ends of that cable? It is standard TV brown coax with a copper core in a white plastic sleeve with copper braid under the outer brown plastic

I repeat: "You can use any suitable double-screened 75 Ohm coaxial cable."
What you are describing is not double-screened.

Thanks again, Sam.

I'll have a look at the cable, but I suspect it is the type D of that interesting article.

The previous owners of this house have a lot to answer for. I'm amazed that we can receive any freeview channels, now.

Many brand new houses have the cheapest cable installed. There really should be legislation! As it's effectively a buyer's market right now, I recommend anyone buying a house have their solicitor write a suitable clause into the contract to cover this situation. A sum should be withheld until the cable type has been checked. It can be very expensive to get it replaced - more expensive than simply replacing an aerial or dish.
