Saorview and Satellite via same cable

jimbob · 07-08-2011 08:05PM #1

Hi

Is it possible to get Saorview (or regular analogue) and Freesat running down the same cable from the attic.
We have a cancelled sky sub box so just want to add the irish channels also.
Is there a special splitter I need.

Combine the aerial and satellite feeds with this http://www.tvtrade.ie/alltrade-tv-aerial-and-satellite-combiner.html.

Split the feed at the TV end with the above in reverse or this http://www.tvtrade.ie/wolsey-tv-aerial-and-satellite-wall-plate.html.

a combiner in the attic and a combiner/splitter wall plate at your tv is the only man by the sounds of it.

Aerial: 5 - 900 MHz
Sat: 950 - 2500 MHz

If you have multiple TV locations you may have to get a multiswitch which effectively combines the 4 possible inputs from a quad LNB, and the UHF aerial down lines which you split at your tv points either by splitter or splitter plate

Thanks a million guys.
Would this also work for a UPC cable input and Satellite? No?

Excellent got an aerial and hooked up old sky box for freesat too.
All working and Saorview works on tv with guide, text, info n all even though its not on the official Samsung list(LE32C450E1W). Must be MPEG4.
Thanks Guys.

this has me thinking, why the need for more than one LNB then for PVR? could you not just split the cable coming from the one LNB?

Very true. Somebody must have tried it. If it did work surely it would just need a regular Y splitter though as the one I needed was for different frequencies(SAT+TV). Or is there a splitter for (SAT+SAT)

A terrestrial TV aerial receives and feeds one frequency band and one polarisation to the TV.

A satellite signal (Sky, Freesat) is split into 2 frequency bands (Lo-Band 10.7-11.7 GHz, Hi-Band 11.7-12.75 GHz), frequency channels/multiplexes in each band are further split into either Horizontal or Vertical polarisation i.e. 4 sub-bands Lo-Band H, Lo-Band V, Hi-Band H, Hi-Band V.

An LNB output can only feed one sub-band at a time to a satellite receiver. If the feed is split between two receivers (after the LNB) for example and one receiver changes channel (and possibly sub-band) - what the other receiver sees can also change.

Twin, quad and octo LNBs allow each connected receiver to independently select the sub-band required without affecting any other connected receiver or PVR.

Then of course we have quattro LNBs which splits and outputs the satellite signal into its 4 constituent sub-bands and feeds each serarately for use with a multiswitch.

I hope that's clear
