Connecting Freesat box to existing sky + dish

jimmy_f

Hi,.
I have a new Manhattan SX Freesat box that I want to connect to an existing sky+ dish. A couple of questions please.
1.)Do I have to change the existing sky + LNB to a universal one to receive Freesat?
2.) The new universal LNB I have( in case I have to change over ) only has one connector on it but there are two going into the existing sky one. Also the Freesat box only likewise has one connector on it. Do I just connect one of the cables to the new LNB and then in turn connect same cable to the Freesat box and if so can it be either of the cables? 
Why does the sky setup have two cables, is one for streaming and one for recording ?
Ps The Freesat box has no record function 
Thanks in advance.

1) If it came from Sky+HD, No.  If it came from SkyQ, then maybe.

2) This is because Sky boxes have twin tuners, so you can record one channel while watching something else.  You just use the one cable if you have only one connector and it'll be fine.  Sky boxes stream over the internet connection.

Sky+/FreeSat have two polarisations and the standard LNB can only operate one at a time hence to enable recording you need two feeds else you could only watch/record channels broadcast on the same polarisation at the same time. As your new box doesn't support recording you can only watch one channel at a time and so it doesn't need a second feed.  SkyQ is different and able to pass both down a single cable. 

Sky+/FreeSat use the same LNB
