Being a n00b to sky am I right in thinking that a Sky Quad LNB will enable me to connect 1-4 STBs independently to a single dish ?

Will It enable each STB or DVB-S cards (with seperate freesat smartcards) the capability to watch and switch channels independently of each other ?.

Many thanks in advance.

You are correct in your assumption. Also note that if your stb has twin tuners each tuner will need a feed off the lnb. You can get 8way lnb's now as well .

8 way cool without degradation to quality ?

Also one last question is it possible to send the signal via the LNB connectors and into my CAT5e house cabling and then out to where ever the STBs are.(this is standard cat5e rated at 300mhz). Typical run would be around 50m via cat5e.

I would not have thought so but this is way beyond my cabling knowledge. Best way to distribute it would be via a proper box.

Certainly looks possible with Baluns might even be get lucky by trying it direct ? :/

Will have to match up the shielding and ohmage but definitely possible.

I'll check the cable specs first before attempting this.

For reference :

Probably see if the CCTV is the better route again will have to find out if this will work... One good thing is that it'll amplify 4xLNBs down a single cat5

The signals from the LNB are between 950 and 2150MHz, so no cat5 will not handle the signals.
The link you posts says satellite over CAT5 but then says its only the sound and video and not the RF it actually sends.

From a quick google search for : "satellite over cat5"

Leads me to : http://www.vtx.co.uk/video/sourcerer.htm and http://www.vtx.co.uk/video/sourcerer.htm#850

It says handles CATV @ 850Mhz (http://www.vtx.co.uk/video/pbe850.htm)

Are the signals from the LNB really as high as 2Ghz ?

That unit handles from 20MHz upto 850MHz. The output from the LNB is 950MHz upto around 2050MHz. It won't work for you.
