Quick satellite question

Paul_Mc1988

So a few months back all the Tv's upstairs lost their signal due to the switch to saorview. So i obtained one of the bunny ears and connected it to a three-way splitter which went to the three Tv's upstairs and now all have the 11 irish stations.

I have a satellite that connects to a set top box in one bedroom that gets itv BBC etc. All Tv's are new and can tune satellite. Could I change the single to three-way splitter to a two input three out splitter and connect both the satellite and bunny ears and tune the BBC channels + rte etc. Any help much appreciated.

No. Satellite tuners need their own connection to the LNB on the dish arm.

The 'switch to Saorview' happened 6 years ago: any analogue channels you were getting were from Virgin (formerly UPC etc.) cable TV.

Ok so the dish has four lmb connection points. One goes to the sky box. One goes to set top box which is no longer in use. So i have three free connection points on the dish. Can i run three feeds individually to the tv's. What happens if you split the feed out of curiosity. Thanks for the help

Sorry I'm not up to date on the phrasing but your right. the analogue turned off and now we're on the soarview. Thanks for clarifying.

Yes, that is what you will have to do.

In simple terms, it just won't work.

Each satellite tuner (in a set-top box or TV) sends a signal to the LNB to select 1 of 4 bands to transmit down the cable because the cable cannot take all the channels at once.

It is possible to view channels on the same band on multiple devices through a split single cable but realistically it needs some knowledge to get a set-up like that working and due to the fact that the channels you are likely to want to watch being spread across all 4 bands it wouldn't be a very satisfactory result.

There is an advanced system (unicable) to allow a single cable be used for multiple tuners but it requires specialist equipment and installation, unless it is all but impossible to run individual cables to each room it is not worth looking at in detail.

Vic pretty much summed it up. Trying to split a sat signal between boxes means they will "fight" for control of the LNB. Running a separate cable to each box/Tv will work. Another thing to keep in mind is for recording. Sat boxes usually have 2 tuners and 2 cables run to them.This allows them to watch one while recording another.

What might work for you is a Satellite & Terrestrial Combiner . You connect you terrestrial aerial to the terrestrial input, and it is then available on all outputs. You connect an lnb output to each input where you require a satellite signal at the corresponding output. This feeds both satellite and terrestrial over a single coax. You then use splitters at the tv end to split out the signals.

I’ve not used these, but I can see no reason why they wouldn’t work. My only concern is that the signal from your rabbit ears may not be strong enough. If so, easily rectified using a proper aerial, which need not be large. There are other options, that some contrib in this forum who work in the Industry might recommend.

Some receivers, and at least one model of Walker TV, support SCR, which would give you two satellite signals, over one coax. I have used this and it works well. However, it does require a SCR capable lnb, which are not the most common one used. (Just saw the 2nd last post, unicable is what I am talking about. I have used it with Sky and Humax boxes, without issue.)

Thanks for all the help guys. I'm gonna run 3 new cables from the dish and see how i get on.. ill probably be back on for more help when i get to the tuning part and inevitably fook it up
