Hi Frank eventually everything was sorted for me
Now if like me you are going freeview and have televisions in other rooms
All the white cables used are in actual fact coax cables
Just fit the end cap onto the harness coming into the house you are then free to go and use the wires for ariel for tv
The junction boxes they go into are simply splitters of the signal you will find the input is the single input at the top of the unit the ones at the bottom are outlets of the input.
The screw fittings are readily obtainable in screw fix or even on line
Just search for "F" connectors and co-ax you can get Just connectors or even short flexible leads
All you need to do is get an ariel put up
Presently I am using an indoor one
You will probably find that you can use them for satellite feeds as well
I have gone with Vodafone broadband
No noticible difference between them and virgin except for the price
For what it was costing me with virgin for BB
I now have BB, telephone, new iphone 13, a second line for my wife's fone and an extra £20.00 in wallet
All the best don't look back and save some money
