The satellite cable is higher grade (ie, thicker), but the impedance of both is 75 ohms, so you can use satellite cable for Freeview, but not the other way round.

It is unwise to mix cable types for satellite downleads. The UHF coax is poor at the frequencies used for the connection between the LNB and the satellite receiver inputs. The change in presented impedance at the cable junction can give rise to unexpected effects, such as some signals not being receivable but others seeming OK.

I would recommend changing the UHF (conventional TV) cables for satellite flyleads using 'F' connectors fitted carefully to avoid short circuits. You can use 'F' to 'F' couplers to join cables together but try to use only one maximum in each lead.

The problem you report could well be because of the use of TV cable and not satellite cable.

I have moved into a new flat. There is an NTL box in the lounge but no cables attached. My neighbour installed an aerial on the roof a few years ago so she can get tv reception. What are my options? Many thanks

Annie : The NTL box will most likely be leftover from where a previous resident has had cable TV and isn't any use for Freeview. If you're in an area with strong signal (please provide a postcode so we can check) you might be able to get away with using an indoor aerial, but otherwise you'd have to get your own roof aerial put up, assuming there is no communal aerial system in the building.
