wixy1503559655 Posted April 14, 2007 Posted April 14, 2007 I just bought a new tv for the bedroom however I can't get any reception with an indoor antenna. The loungeroom tv gets reception just fine with the same type of indoor antenna. So my question is, can I just get some kind of splitter and run a coaxial cable from the antenna in the loungeroom to the tv in the bedroom? i.e. use the same indoor antenna for two tv's each with digital set top boxes. Cable length would be around 15m.
digitalj Posted April 14, 2007 Posted April 14, 2007 You can, but for the tv in the lounge room, your signal strength will drop by 3dB and the signal for your bedroom tv will be a bit weaker than the signal for your lounge room tv. What is recommended is an antenna installed on the roof and using RG6 Quadshield and F-connectors. What you could try is walking around your bedroom with your current indoor antenna to see if you can get signal anywhere at all, like if you move an antenna just 10cm in one direction, it can be the difference between no signal and perfect signal. But once again, roof antenna is best, or are you in an apartment?
pgdownload Posted April 14, 2007 Posted April 14, 2007 Have you tried the bedroom Tv connected to the lounge room antenna? I'd find it unusual you're getting 'no' reception at all - suggests something else might be the issue. Regards Peter Gillespie
mtv Posted April 14, 2007 Posted April 14, 2007 If we are talking digital reception here (which we should be) the lounge reception could be borderline. Moving the antenna to a different position (room) could be the difference between good reception and no reception. As Peter suggests, try swapping STB's and antennas. Indoor antennas are generally very poor performers. There is no substitute for a properly installed external antenna. If you have reliable digital reception with an indoor antenna, you are very fortunate. Depending what the signal strength and quality is currently, splitting the signal to two receivers may reduce the signal level/quality below the required minimum and you may find you have no reception on the lounge STB as well. Only one way to find out.
wixy1503559655 Posted April 14, 2007 Author Posted April 14, 2007 It's not possible for me to have a roof antenna as I rent. I've tryed swapping stb's as well as moving the antenna around in the bedroom but have only managed to pick up Channel 7. I guess what I could do then is put the antenna in the loungeroom, as that's where it seems I get the best reception, and then and run a coax cable back to the bedroom?
mtv Posted April 14, 2007 Posted April 14, 2007 You could, just keep in mind that you will get a bit of loss over 15 metres of cable, so ensure you use good coax, like RG6 Quadshield.
wahroonga farm Posted April 15, 2007 Posted April 15, 2007 I suspect quadsheild isn't always the 'most lossless' RG6. Anyway here's a little graph of a typical 100m of RG6 showing loss and where the Aussie DVB-T shannels fit in. If you have 10m of cable divide the 100m dB loss by 10 etc.
I am not a duck Posted April 15, 2007 Posted April 15, 2007 I just bought a new tv for the bedroom however I can't get any reception with an indoor antenna.The loungeroom tv gets reception just fine with the same type of indoor antenna.

Cable length would be around 15m. The simple response to this question is that instead of using a splitter, run a cable from the loungeroom STB RF OUT terminal to the bedroom STB. If it is going to work, the slight signal gain provided by the boosted splitter in the source STB should allow the bedroom STB to function. Of course this will not overcome imperfections in reception at the source STB as a result of using an indoor antenna, but for the sake of a length of coaxial cable, what is there to lose?
