Joining shot gun cable

[phil100uk]

Good afternoon , just a quick question about joining cable .

If i run 2 seperate shotgun cables to feed 2 sky + boxes that i want fitted in the future , can these be joined using f type plugs to a new dish with a duo lnb and 2 feeds coming down to the 2 shotgun cables without losing to much picture quality . Thanks

It will have zero effect on picture quality.

Digital is all or nothing. You either have an excellent picture or you have a screen full of coloured squares (or nothing).

If you mean can the duo LNB feed both shotgun cables then NO. You will need a quad output LNB to feed both cables

A sky+ box requires two cables for full operation although you can go into the engineering menu and change an option so it only requires one cable. This limits you to recording only one thing at a time and normally only done for flats etc where you cannot get a second feed. So ideally you need four cables.

There's no such thing as a "duo LNB" so I must have subconsciously ignored that! If you mean a "twin-output" LNB, then it has two outputs. There's no way you can split it to get four. As another poster stated already, you need as many outputs on the LNB as you have inputs on your Digibox(es). So it sounds as if you need a quad-output LNB to provide four feeds. An "OCTO" LNB would provide 8 feeds.

(If you needed even more, you'd have to use a "Quattro" LNB and a "multiswitch".)
