There are two ways of sharing out the signal from a satellite receiver to multiple receivers. One method is via the building's TV coaxial lead and the other method is using a video sender.
If the satellite receiver has a coaxial output on it, then all you would need is a 'Y' coaxial splitter. Place the leg of the leg of the Y splitter in the wall outlet for the aerial, connect the TV or VCR to one output and the TV out of the satellite receiver to the other output of the Y splitter. No connection should be made to the coaxial â€˜inâ€™ of the satellite receiver using this method. This is how I have it done at home Just note that the satellite picture in the other rooms may not be perfectly clear, especially over long cable runs. You may have to select from different channel number outputs from your satellite receiver, retune the TV in the other rooms to pick up the new channel until you get a clear picture that does not interfere with other channels.
A video sender is the equivalent of having a wireless scart lead. There are two parts to a video sender; the transmitter and the receiver. The video sender transmitter usually has several inputs such as Scart-in, composite-in and L/R audio phono-in. The video receiver has matching video outs and some brands also has a coaxial out with a built-in modulator to worth with older TVâ€™s that do not have scart or composite in. Most video sender units allow receiver add-onâ€™s for multiple TVâ€™s. Some brands also have Infra-red relaying between receiver and transmitter to allow channel changing in a room where a video sender receiver is located.
While the video sender generally gives a very good quality picture, there are a few things to watch out for. Video senders operate on the 2.4GHz unlicensed wireless band which is also occupied by wireless computer networks (802.11a/b/g, etc.), cordless phones, other video senders (neighbours house) and even microwave ovens! :eek:
If choosing a video sender, it may be worth considering one with a long range as well as multiple band support. The longer range will ensure a better picture through walls and floors throughout the apartment where as band selection helps get around interference problems. Wireless LANs are known to put zigzag lines through the picture on some bands and microwave ovens (especially leaky older makes) are known to overwhelm the signal altogether regardless of the band. :a
Try searching Amazon for video senders. This will give you an idea of the various makes
