Hi guys,
Since I'm ditching Sky TVs conventional mysky with multiroom sky box package and going with a single HTPC with a quad tuner and streaming live tv via Media Portal tv-server to the other TVs with computers attached to them, will I have problems with lnb signal strength and frying the lnbs?

In this post: http://www.geekzone.co.nz/forums.asp?forumid=83&topicid=40568 they talk about having more than one device sourcing power it could fry something (some clarification needed), Will I need a specific lnb splitter to deal with this?

So I am getting the signal from one sky dish and splitting it into four for each lnb. Currently in our house we have two lnbs connected to a mysky hdi box from a hole in a wall behind the TV (using one of sky's own splitters, and I believe from all the cables behind the Tv the second rooms skybox has a single cable running under the floor to that room, with a DIY kiwi attitude maybe a could cut (special equipment maybe?) into the wire leading into the other room and put a cable ending onto it and get a 1 to 2 splitter, or I could leave that cable altogether (for future use, say when we move or I leave home) and run a splitter unders sky's splitter or replace their splitter with one of my own.

Any ideas?
Thanks,
William

Hi guys,
I have done some research, if I get this splitter: http://www.freeviewshop.co.nz/satellite-terrestrial-splitter-p-165.html
This will solve the lnb frying problem right? Secondly, Will I need to pair this with an amplifier? http://www.freeviewshop.co.nz/10db-inline-satellite-amplifier-p-58.html
Will this be required to still get good quality signal from all four ports on the quad tuner card?

Hi William,

I've got a simple quad splitter (http://www.freeviewshop.co.nz/input-output-satellite-multiswitch-p-51.html) which I feed two cables from the LNB in (13v and 18v) from which a single cable feeds each tuner.  I do not have an amplifier on this system and the signal quality is generally in the 80s/90s.  So far no problems at all with my system which has been running for well over a year now.

Chris

So, does it have clear quality then?
Are then image defects or artefacts?
Please let me know

clear quality, obviously when there is rain or other atmospheric conditions, the picture can drop slightly but to be honest 99% of the time it is 'perfect' (the caveat being that SD looks fairly poor on an HD screen and HD is still not such a high bit rate at times).  If anything the quality of the channels is better than the HDi box simply due to the power of the GPU and the various de-interlacing algorithms I can use!

EDIT:  Would recommend the splitter I posted above.  It is what you need to ensure you get a continuous feed.  A normal splitter won't allow for Horizontal or vertical polarity changes at the same time.

Hi what if I used two 2 way splitters instead of a multi-switch it shalf of the price and would allow me to use both polarities right?

Not quite, a single input splitter would allow either H or V polarities at any given moment, however if a card is receiving one polarity, the other card would be unable to tune to the opposite polarity; In essence you could lock tuners out from tuning to other polarities.  In this case however, as all Sky/Freeview channels are on H, you should be able to run it fine ASLONG as you don't try to tune any V polarity channels from D1 that you might find.

As long as the splitter has the correct MHz ratings then you should be fine and at about $13 per item if one doesn't work it isn't such a waste.
