Combining aerial signals into 1 cable

This triplexer can combine UHF TV, FM radio and DAB radio aerial signals into one cable.

Downstairs you can use a second, identical triplexer) maybe fitted to a plate with holes drilled through it or wired to a plate with separate sockets) or a commercial diplexer plate (UHF and Radio). In the latter case you use a simple "Y splitter" to get the two radio signals.

Note: the V24-310 can pass DC from the combined output to the UHF input if you need to power a UHF masthead amplifier.

Combining aerial and satellite signals

A couple of DIP2 diplexers will do the job if you just want UHF and LNB signals.

If you want additional signals and functionality, sometimes the simplest way is to use a Loft Box.

But, if that solution is more than you need, you can base your design on the following sketch. The combiners shown below can be used in a variety of ways to get several signals into one cable. (Each can be used in reverse to decombine signals from one cable). Or you can use a suitable "diplexer" or "triplexer" wall plate to decombine (separate) the signals. Please note that such a system may not support a "magic eye" remote extender.

(Because the DIP2 carries voltage to the LNB it will also carry a 22kHz DiSEqC signal. Consequently, this system can also be used where you have more than one LNB on your dish, selected by a DiSEqC switch.)

Frequency in MHz

For a better understanding, please look at the frequency chart, above. The frequency bands of interest are:

  • the LNB band, stretching from 950 to 2150 MHz
  • the UHF TV band + VHF TV band, from 470 to 806 MHz
  • the FM and DAB radio bands, from 87.5 to 240 MHz

A diplexer can handle two of these bands. A triplexer can handle all three.

You can feed a triplexer with signals from all three bands and use another diplexer to separate them. Note that FM and DAB can be combined and separated by the V24-310 (above) because it is really a true "quadplexer" but a triplexer will keep DAB and FM together. This doesn't usually matter because you can use an ordinary splitter to get two lots of signals from the "Radio" output and feed one to an FM radio and one to a DAB radio. The radios will use whichever signal they want.

Note that this system does not permit you to combine, say, two LNB outputs into one cable because they both use the same band of frequencies. If you wanted to do this the only way would be to use a "stacker/destacker", which artificially creates a higher "LNB" band above 2150 MHz. The cable used for such a system has to be exceptionally good. SatCure does not stock staker/destackers because they can cause problems if the wrong cable is used, or even the wrong length of cable.

See page 15 to order these items.

IMPORTANT NOTES!

You should use fully-screened cable* for all connections. If you are trying to use existing TV aerial cable then it should be OK for the V24-310 but it could cause problems if used with the DIP2, since this carries the high frequency LNB signal. It might work provided the cable is fairly short but obviously we can't guarantee it. The usual result of using the wrong cable is that some satellite TV channels will be missing or suffer intermittent picture break-up (although this can also have other causes).

*We sell only fully-screened cable.

If you connect a masthead amplifier between the TV Aerial and the V24-310, please note that its power supply (if separate) must be fitted in that same cable OR between the V24-310 and the DIP2 (drawn in red). You MUST NOT fit an amplifier anywhere in the "drop cable" from the DIP2 because that cable carries the LNB voltage supply from your Digibox!

If you wish to distribute all these signals to other televisions, you should connect your Sky Digibox "RF outlet 2" to a SkyLink compatible amplified splitter with the required number of outputs.

If you don't have a satellite dish and simply want to combine aerial signals, omit the DIP2. The cable marked in RED goes down to your decombiner wall plate or to a second V24-310.

If you don't have radio aerials you simply omit the V24-310. Your LNB and TV aerial (red) feed the DIP2. The downlink feeds another DIP2 or a decombiner (diplex) wall plate. Easy!

IMPORTANT!

The basic systems discussed here may not be suitable for a house where you want TV in several rooms. Before making a final decision, please read our information about LOFT BOXES and our information about MULTISWITCHES and about splitting the Digibox RF to one or more rooms.


Example

We currently have our sky hd box in our bedroom.I want to put it into our conservatory directly below and bring a return cable back up to the bedroom so we can use a sky link or whatever the proper name is obviously that bit is simple enough as I have plenty of cable in the loft to channel this in to the conservatory.What else I want to do while I have the wall chiseled out is to take cables down from the loft into the conservatory for tv/freeview and fm dab should we ever take sky out.I've bought a labgear psw351t quadplex faceplate for the conservatory but want to make sure i dont need anything else and how to wire the cables in.Also on the faceplate in our bedroom I'd like to not just have the sky return from the sky box below but I'd like another port for freeview etc from the loft incase as before we remove sky.So far I've ran the cable for the return from the conservatory to the bedroom and a cable from the loft for the tv/fm feed.one final thing as we are going to put the tv on the wall in the conservatory I want an aerial socket on the wall behind the tv so would this be a seperate cable into the loft.Am I using too much cable and is there an easier way to do this job your input would be helpful?

(I don't usually spend an hour answering a question such as this without payment for my time but, since this wasn't specifically explained on the web site, I decided it was worth adding to this page.)

Please see attached diagram. You'll need (as a minimum):-

The "DIP2" is a diplexer, which combines the aerial and LNB signals into one cable (shown in red) and passes power to the LNB, if required.

The 304114 wall plate incorporates a triplexer (SAT1, TV and Radio) to separate the signals. Radio isn't used here, but, with the addition of another diplexer (see V24-310 above), it could be. The plate also has a straight-through connection of LNB2. The aerial signal feeds a Digibox, gets combined with the selected satellite TV channel and comes back from Digibox RF2 output to the RF (return) socket to pass signals to the bedroom GLO27 wall plate. A satellite TV receiver with RF output will work.

For "magic-eye" functionality, you'll need a Digibox which supports this (or a conversion kit) and the "return" path must supply power to the "eye". It's important to use the correct wall plate (screened with DC continuity - not "isolated") and double-screened cable throughout, to minimise risk of interference causing poor picture and/or unreliable operation of the remote.

Read about the 304114 wall plate click HERE.

OPTIONALLY you could use the same wiring to feed several rooms, simply by replacing the single-socket with an amplified splitter, like this:-

The amplifier can be powered directly by a Sky Digibox via the "Return" socket or via a separate power supply (necessary if there are more than 4 outputs or if you don't use a Sky Digibox with RF2 output - e.g. FTA receiver or Freesat with separate RF modulator connected from the Scart socket).


One thing I should mention about wall plates: most of them are designed so the cables have to enter them from below. This can be awkward if the cables are running down behind "dry lining" or similar. You need to leave plenty of room for gentle loops going below the plate and back up. Take great care not to kink the cables. Our thin WF65-1 cable facilitates tighter curves.

Combining SAT and TV into one drop cable

Combining SAT and TV into one "drop cable".

Uses two DIP2 diplexers and a 100-00677 Maxview screened UHF + SAT non-isolated wall plate.


Combining SAT and TV into one drop cable 2

Combining SAT and TV into one "drop cable".

Uses a single DIP2 diplexer and a Televes 8241 Satellite/aerial decombiner outlet plate.


Combining SAT and TV into one drop cable 3

In this example, the LNB signal goes down the cable and the RF signal goes up the cable to a distribution amplifier. (Note that the LNB current feed also goes UP the cable.)

Q. Can I use a "magic eye" with this system?

A. Probably not.


Combining SAT and TV into one drop cable 4

Alternatively, use a single DIP2 diplexer and a Televes 8241 Satellite/aerial decombiner outlet plate.

Q. Can I use a "magic eye" with this system?

A. Probably not.

Go to catalogue page

a pair of UHF diplexers

If you have two lots of UHF signals to send up or down (or both) a single cable, you may be able to achieve this with a pair of UHF diplexers.

This example shows a 21-33 + 35-69 diplexer where the numbers represent the UHF channel numbers (21 is the lowest frequency UHF channel in the UK).

Q. Can I use a "magic eye" with this system?

A. Probably not.

Note: diplexers are no longer manufactured.
