Combining two "aerial" signals

langdang

Hi,
Have Saorview working on indoor aerial.
Have a feed from a communal source that gives me some freesat channels. (I don't have the box, the box is elsewhere at some communal dish, it's distributed to 10 or 20 duplexes).

What I can't get is both together - my indoor aerial has an input for an external aerial, but I lose the Saorview reception if I connect the communal signal from the wall into this aerial.

If I connect both at the TV with a Y connection, the same happens - TV tells me I have weak or now signal on the Saorview channels. (not sure the Y connection was a good idea at all)


So is there a cheap way to combine both these signals but buffer/isolate them from each other or whatever?

Thanks in advance TV gurus...

Unfortunately you can't just add two signals together by connecting them, you need some electronic summer in the middle. I presume there's something on the market... Do you know what frequencies the freesat box outputs?

You could connect the communal connection to the tv and connect the aerial to a cheap box for the saorview channels.

something like this?


similar on e-bay, less than 3 quid

Tv is saorview compatible, but if it comes to it yes that could do

Just thinking, if you have an old vcr lying around you can plug one of the cables into that and use it as a tuner over scart.

Maybe one of the channels that part of the communal system are on the same channel as your local saorview transmitter . Are any of the communal channels affected when connected through the aerial?

Ya. I shoulda known better! Last time I did anything RF a power splitter/combined wasn't exactly 2euro in Malplin haha. Dunno what frequency, to the tv it just looks like a normal aerial, picks em up on autotune.

It will be several satellite receivers or tuner modules (1 for each service) outputting analogue signals on separate channels.

If there is a conflict with the Saorview transmissions in your area, then go with one of the suggestions already mentioned: either the manual switch, or a separate Saorview receiver with your indoor aerial & use the tv's analogue tuner for the 'satellite' services, or use a VCR's analogue tuner for these & the tv's Saorview tuner with your indoor aerial.

That way, the 2 conflicting signals are kept separate & with the latter 2, you can switch between sources with a remote (maybe someone will come up with a remote controlled switch).

The communal tv system really should have the Saorview signal included.

Celtic tiger / nama / management company unfortunately - won't hold my breath waiting for piped saorview!

Ironically, the only scart/aerial yoke I have is a freesat box. Might work, hope it has a terrestrial aerial input, just another remote etc grr

What channels are supplied thru the communal system?
Are the Irish channels available now thru the communal system or did they go with analogue switchoff on Oct 24th?

Itv, BBC etc. Irish channels gone since analog switch off, had had the red x and October 24 warning on them for ages - I held out in the faint hope of a solution being provided!

Maybe a silly question but have you tried tuning in the Saorview channels thru the communal system? If so and had no luck why not contact the management company regarding the situation, Saorview should be easily carried on the system, a single frequency/UHF channel replacing the 4 previous analogue channels. I assume everyone else on the system is in the same position i.e. no Irish channels?

Yeah, that was the first thing I tried - retuning.
Maybe everyone else has it - if there was an "enabling fee" then it's quite possible my predictably useless absentee landlord wouldn't cough up.
I'll talk to some of the legitimate inhabitants.
