For some time now I've been wondering how difficult/expensive it would be to get a really tidy and reliable multi-Satellite TV setup up and running.
I have limited knowledge in the satellite TV department so I thought I'd ask for some advice...
My current setup is a 90cm (I think) fixed position dish with a single 11300 ku band LNB focussed for Optus D2. The cable is connected to a Phoenix FTA decoder in the lounge (~5-10m length), and then daisy chained a PC with a dual hybrid and dual DVB-S PCI-e tuner in an adjoining room (~10m length).
I'm not exactly certain of what is possible/available, but I think I'd like to add Optus D1 (for Freeview) and (if possible) Optus C1/D3 (recommendations for other satellites with FTA channels are welcome!). I know there are probably a number of ways to do this, but I want to keep cable clutter and expenses to a minimum. I have also heard the following things through the grapevine:
1. Multiple LNBs can be mounted on a single dish, either by bracket or by using dual LNB hardware.
2. Dish size is a factor when considering point 1.
3. Aerial/dish signals can sometimes be multiplexed onto a single cable.
Now I don't know if this would be possible, but here is what I was thinking about doing:
1. Mount 3 independent LNBs on the existing dish using a bracket.
2. Select the LNBs in such a way that the 3 satellite signals could be multiplexed onto a single cable.
3. Multiplex the signals at the dish.
This approach would mean no need for extra dishes, no need for extra cabling, and no need for extra decoders. The ultimate question is really whether that setup is feasible...
I have concerns:
1. Multiplexing, cable length and signal quality: currently the Phoenix decoder shows 100% signal level and quality and picture is great (or as good as highly compressed MPEG2 ever gets!), however I get the occasional glitch on the PC. MediaPortal signal level is ~75% and quality ~60%, however I do wonder whether it is related to signal issues.
The question: is the multiplexing of 3 LNB signals possible, and how would signal quality be affected?
2. Tuning/focussing with LNB brackets: I have no experience with Satellite tuning and no equipment to do it with; I also don't know anyone that does. I have heard that a multi LNB setup on a single dish can be finicky for tuning.
The question: how hard is it to hire/contract someone to focus LNBs, and how reliable would a bracketed 3 LNB setup be?
I am an engineering student but I don't have a lot of experience with satellite related issues so I'm probably either pushing my luck way too far or overlooking some issues. Any advice would be most welcome!
Thanks in advance...
