Hello,

Situation
---------
I have a nicely cabled appartment with a cable that my carries Cablecom TV signal from the basement to my living room. There is only one physical cable that is laid in the walls and winds about under the floors (and so cannot be easily nor cheaply replaced nor an additional cable easily nor cheaply laid).

Needed
-------
I would like to have Satellite TV as well, with a dish outside my appartment. I would like the Satellite signal to be carried along the same physical cable (that is within my appartment and that I owe - both the cable and appartment that is...) that my current Cablecom TV signal is carried along.

Questions
---------

Does anyone know if this is possible?


A Cablecom "technical chap" in a MediaMarket store in Brunaupark said this was not possible, since the Cablecom signal uses non standard(?) frequencies.

However I think that the Cablecom signal must only use certain frequencies and these may not overlap nor interfere with a satellite TV signal ?

I'm aware of Input duplexers, that can be used to split satellite TV signals (SAT input 950 - 2250 Mhz) out from terrestrial TV signals (5-862 Mhz).


(1) However is there such a thing as a Input duplexer that will split Cablecom TV signals out from Satellite TV (which are on the 950 - 2250 Mhz frequency range).

(2) Anyone know what frequencies Cablecom TV is sent down cables on?


Hoping someone on this forum (a) understands the problem and what I'm on about and (b) can help with info/answers.

Many thanks
regards Jon

You will need to check whether there are already any splitters in house to extend your connection to different rooms.

1. You will need to have all extenders in 5-2000 or similar range to have all signals travel to your sockets if you are going to mix it up.

2. Many cable splitters have satellite pass through, so go for those ones.

3. If you get a socket with cable and satellite outputs then you can just plug you receiver box/TV to different sockets that will take care of proper signals.

3. Cablecom signals are <950 and in same range as all broadcast, and will coexist with your satellite signals on same wire.

You can find these sockets and splitters in Migros Haus/Garden, Coop (bigger ones for house/tools etc), Obi and Bauhaus. Go to the satellite section which might be separate from normal electrical / TV/Cable section in some stores.

Hope it helps.

[QUOTE=Jonathan_hughes76;385313]Cablecom runs on <850 MHz

You can combine the satellite IF feed (>950 MHz) and the Cablecom feed

HOWEVER if you do this with a cheap and nasty splitter, you run the risk of creating interference to all users in the same building, due to the signals mixing and intermodulating with each other.

A spectrum analyser is required to see the effect.

The proper way to do what you want is with a combiner / amplifier, which has specific filtered inputs for cable TV and for satellite TV.

We have one in our house - although not being used as per your wish.

You best bet is to talk to a satellite installation company who specialise in apartment blocks - they will have the necessary kit for the job.

Thank you whynhow and FriendlyKiwi

As you correctly identified I have extenders in the 5-2000 Mhz range, that travel to various sockets around the appartment. I would have to put the Satellite feed into these as well.

If Cablecom signals are in the < 950 Mhz range than it seems they are in the same range as as broadcast/terrestrial TV signals (5 - 862 Mhz), then it appears that all I require is to check if my wall sockets have cable and satellite outputs and see if "you can just plug you receiver box/TV to different sockets that will take care of proper signals". If not then use "good quality" Input duplexers.

The job may be more straightforward than I imagined.

Many thanks for the guidance.
