The Dumb One
YesYep.
Just to double check can I buy a new LNB as long as its compatible with sky HD etc and just switch them over?

As its got 4 connections do we still just use the existing 2 connections? And does it matter which ones we connect to on the new LNBYep. That's the problem. It's a wideband LNB supplied by Sky for SkyQ.
You need a 'standard' LNB like
Easy to swap if access to the dish is easy.
Change the LNB and it will spring into life as if by magic.
Thank youAs nobody else has replied, my opinion:
If you only need two cables, a twin LNB might be cheaper than a quad. If you use a quad, make sure the unused ports are properly sealed against the weather (maybe they are supplied with caps - as an engineer, I would put some grease in the caps before fitting them, Vaseline would do).
As I understand it, each channel on a multi-port LNB is able to select any quadrant separately (according to the control signals that come up the cable from the receiver) - high band or low band, horizontal or vertical polarisation. By having four ports, each port can be configured to a different quadrant and thus receive everything simultaneously - but that doesn't stop any one of the ports switching between the quadrants if required, so yes, just connecting two cables should work fine, and it doesn't matter which ports you connect to.
Communal satellite distribution systems have a distribution box which take all four feeds and a different quadrant on each, and then the control signals from the various subscribers STBs select which quadrant to pass on, controlled by the distribution box.
Isn't that a reasonable conception then, as would be the common understanding outside satellite-geek circles?And from a member who is usually a stickler for precision and accuracy.

Reasonable conception, but wrong.Isn't that a reasonable conception then, as would be the common understanding outside satellite-geek circles?
Going back a bit here to earlier post. A factory reset will not erase the recordings unless you specifically ask it to.Was considering a factory reset but dad doesn't want to lose the stuff he's saved on the hdd

I've also seen some LNB's with 2 outputs
I've seen screwfix do one that he can collect today

Perhaps you would do well to take your own advice. Especially as everything you've posted has already been overtaken by events.If not perhaps ignore anything this poster posts,
In what way incorrect? I'm not a satellite expert, but I had the gist right and it was posted in the absence of better advice. In fact, for all practical purposes, I was spot on.No idea where Black Hole got this totally incorrect info from.
