Installing a multiswitch

A multiswitch allows you to feed many satellite TV receivers in various 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.

SatCure supplies multiswitches with Quattro LNB inputs, aerial input and up to 48 outputs.

*(More complex multiswitches that are compatible with a quad-output LNB are manufactured. I am personally not convinced about the reliability of operation with a quad-output LNB. Nobody makes a Quattro LNB to suit an oval Sky minidish. The dish has to be circular, as seen by the Quattro LNB.)

A twin-tuner "PVR" receiver requires two cable connections from the LNB for full functionality.

A multiswitch requires FOUR cables from the Quattro LNB, as shown.

Using coloured WF100 cables makes it easier to determine which end is which.

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. If you don't need the Sky signal, you can use a TV/Radio diplexer plate instead. (The FM/DAB signals come from a single outlet so, if both are required, you can use a simple "Y" splitter.)

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) or a "Quadplex" plate that is basically a triplexer with an additional "F" connector.

Where ONLY satellite feeds are required in a room, you can use a single, twin, or quad "F" connector wall plate.

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.

Please note that we can give only limited help and we will not design your system. If your question requires sight of your wiring diagram, please upload it before contacting us.

It has come to our attention that a batch of Vision V75- Multiswitches may have been fitted with substandard power supply parts. If you have a power supply problem with yours, you can either return it to our appointed repairer (with proof of purchase) or order a (free) repair kit from us (requires basic soldering skills). Please contact SatCure Technical for more information. If you did not buy your Vision V75- Multiswitch from SatCure, you can buy a repair kit from us: click HERE.
