Installing a multiswitch
A multiswitch allows you to feed several rooms with satellite TV signals from a QUATTRO LNB on your dish.* In addition, if you wish, you can also feed aerial signals from a UHF TV aerial or, with the addition of a V24-310 triplexer, any or all of UHF TV (analogue and/or digital), FM radio or DAB.
*(More complex multiswitches that were compatible with a quad-output LNB used to be manufactured but production ceased because of (I assume) reliability problems and/or cost.)
DISH SIZE
In general, it will be found beneficial to use "the next size larger than normal", for three reasons:
- A multiswitch has losses and, although some incorporate signal amplifiers, providing a better signal to begin with will reduce the percentage of "noise" added by the amplifier.
- Most installations that use a multiswitch will use longer cable runs than a "normal" house, resulting in more signal loss.
- QUATTRO LNBs are not available for (oval) Sky minidishes so you'll have to change your dish anyway.
Each output of the Multiswitch should be connected to a satellite outlet plate or, if you want the TV and/or radio signals as well, to a Triplex plate (shown above) which separates the signals. (The FM/DAB signals come from a single outlet so, if both are required you can use a simple "Y" splitter.) If you don't need the Sky signal, you can use a TV/Radio diplexer plate instead.
For Sky+ or Sky+HD or other satellite PVR having two tuners, you will require TWO wall plates (or a double-width bezel fitted with two modules).
Where ONLY satellite feeds are required in a room, you can use a single, twin, or quad "F" connector wall plate. Where satellite and aerial feeds are required in one room, you'll need two Triplexer plates or modules), which you can fit to a double-width wall box.
EARTHING REQUIREMENTS
If a multiswitch is feeding separate dwellings, which may be on different mains power supply phases, it is essential to get a qualified electrician to "earth-bond" the multiswitch. He will understand what this means and will know how to do it. Please consult him first, to ensure that the multiswitch is installed reasonably close to a suitable earthing point.
