AlexJames Posted January 3, 2011 Share Posted January 3, 2011 Hey All, I have just moved into a house with a satellite. The owners use free sat, where as I have free view built into my TV. Would something like this ... http://www.gizoo.co.uk/Products/AvCommunications/TvGadgets/AVSender.htm?spmc=TGSPPCGGP487&gclid=CNGj1YSRn6YCFY9O4QodWj79Xw ...only display what's on the master TV? I guess it depends where about's in the chain the transmitter is? Anyone know how these work? or if there's a better way other than putting a 'y' connector on the incoming satellite able and trailing cables through the roof?

JustGav Posted January 3, 2011 Share Posted January 3, 2011 That transmitter only broadcasts video/audio not the actual antenna/sat signal. You also can't y-piece a satellite lead unless you know it is a secondary and not providing LNB power. Unless you have an antenna freeview won't work. Personally I'd get a freesat box, the picture quality isn't bad and there are a few more channels. Quote Link to comment Share on other sites More sharing options...
Shane Posted January 4, 2011 Share Posted January 4, 2011 Freeview requires a feed from a terrestrial aerial and free sat requires the feed you have from a dish. As Gav says you can't just t into a sat feed, but even if it is not carrying LNB voltage you still cannot do it. The feed from the dish carries one of 4 RF polarities from the dish, one of these 4 is selected by the receiver which sends either 13v, 18v, 13v +22 KHz or 18v +22KHz. So even if you where not sending DC up the second "t" feed if the first was calling for say lowband vertical at 13v and then the second receiver was calling another polarity then its game over. What you could do is use a Johanson stacker/de-stacker combination on a single cable, if it was two receivers you wanted to run on a single cable, but there are limitations, first the feeder cable has to be good and you would also need to make sure there is a second feed available on the LNB (dish). You also may be able to diplex the UHF freeview signal with the sat signal down the same cable, but would need more details of your layout to be sure on this. As Gav says, the box in your link just converts AV signals from a source into RF, the other half then receives it and converts it back to AV, also if there is a microwave oven nearby then that will wipe it out as the sender in your link operates at 2.4GHz. The newer 5.8GHZ ones overcome this, but do cost a bit more. Quote Link to comment Share on other sites More sharing options...
Matt H Posted January 4, 2011 Share Posted January 4, 2011 Just buy an aerial from Tesco? Why are you overcomplicating the simple? Or am I missing something? http://direct.tesco.com/q/R.208-6107.aspx Quote Link to comment Share on other sites More sharing options...

That aerial would be great for freeview, if you lived within about 5 miles of Sandy Heath. Indoor aerials are rubbish for DTT unless you are in a really good reception area.

When I lived with my mum, I had freeview with a boosted aerial l in my bedroom. She lives in the middle of nowhere and reception was fine as long as it was in the right position.

Generally speaking, indoor aerials provide their best efficiency at only part of the TV UHF spectrum, meaning that when used for DTT you tend not to receive all the multiplexes and end up with channels missing, but it really does depend on signal levels at your location and also on how many channels you want to receive.

AlexJames Posted January 4, 2011 Author Share Posted January 4, 2011 Humm, you've all given me allot to think about on this one I tell ya, but thank you!.. its not gonna be as simple as I thought.... Maybe an Ariel is the best for me? This is me being a noob when it comes to satellite etc... but I didn't think a digital signal could be received through an Ariel? What do other people do when they have more than one TV in their house? Quote Link to comment Share on other sites More sharing options...
Shane Posted January 5, 2011 Share Posted January 5, 2011 OK, Freeview (Digital Terrestrial TV) is received via a aerial, be that indoor, outdoor or from a building's distribution system, whereas Freesat is received via a small parabolic dish pointed at 28° east of south, which is also where Sky Digital signals come from. Now just to make it even more confusing, there is Freesat from Sky also, but at this point lets not go there. You need to decide what's best for your situation. Personally, if you have access to a dish then I would go for Freesat, but that's my preference, and I can probably help you through getting this going. If you just want a handfull of channels and are looking for the cheapest most hassle free approach then why not give Matt H's idea of using a indoor antenna? Especially as your TV already has Freeview built in, but dont expect it to be perfect on all channels all of the time using a indoor aerial but it could get you up and running the quickest. Also, one last option is maybe just to use the analogue side of your tv on an indoor antenna and see what results if any you get. Couple of questions: Am I right in thinking there is no TV aerial on the building and only a dish? Is the dish close to the room where your tv is and is it easily accessable and if so could you get a cable from the dish to your TV without too much fuss? How many cables go to the dish? Humm, you've all given me allot to think about on this one I tell ya, but thank you!.. its not gonna be as simple as I thought.... Maybe an Ariel is the best for me?

Another vote here for freesat If you just want a handfull of channels and are looking for the cheapest most hassle free approach then why not give Matt H's idea of using a indoor antenna?

After six months of almost daily going up and down the ladder to adjust my ondigital connection I vowed never to use an aerial again... had a moment of madness a few months back and tried again, realised why I never bothered and gave up again. (using a large externally mounted antenna as well). Quote Link to comment Share on other sites More sharing options...
JustGav Posted January 5, 2011 Share Posted January 5, 2011 My solution is a little more involved, but basically put a server in with either a freesat or a freeview card and then you can watch it anywhere in the house that you have a PC Quote Link to comment Share on other sites More sharing options...
Shane Posted January 5, 2011 Share Posted January 5, 2011 Can't beat it really for free, especially with HD channels too. Shame Sky have confused things by calling their FTA service Freesat from Sky though.

(using a large externally mounted antenna as well). You and so many others! At the moment so much depends on where you are and the field strengths in your area. Central London for example is great and we use DTT for our inhouse channel line ups and cable systems, but where we have systems in Kent, Newmarket, Gloucester it's been an uphill struggle and we take our feeds from freesat. Once analogue has gone and the power levels are brought up it should improve things though.

AlexJames Posted January 6, 2011 Author Share Posted January 6, 2011 Thanks guys, thats been really helpful actually I think I will do matts way short term. There is an analogue cable coming into the house yes, so I might be able to thieve that... but we shall see! Ill let you know on the outcome! Thanks again!
