Hi
I would like to connect my hi-fi's tuner to my TV's communial
aerial socket on the wall with the aid of some sort of coaxial
splitter, is this possible? On the rear of the hi-fi are the aerial
connectors which appear to accept strands of exposed wire by
pressing and releasing a small lever. The five connections are
split between 300ohm, 75ohm and AM. Whats the best way to get a
decent reception from the tuner? Thanks for any advice.


You can get passive splitters that are fairly good devices. Try any
radio- TV parts store for one of those. Connect one output to your
regular TV's antenna connection and the other to the 75ohm input on
your tuner. This will get you any FM signals that are being carried
on the communal system. For AM, you're better off just attaching as
long a piece of wire as you can, unless you want to get into special
active antennas.

Thanks for the reply Dave.
From my question you will probably realise that I am a complete novice

here. Can you send me a link to an image of the passive splitter you
have in mind. Everything that I looked at on the web did not seem
appropriate. Just to elaborate I will be able to connect a two
stranded wire to the back of my hi-fi's tuner aerial sockets (To the
75ohm inputs as you recommend), so how will I connect the other end of
the wire to the passive splitter?


Use a piece of coax. RG-59 should work for this run. Put an F-connector
on one end and just cut the other end open and split the braid from the
coax. The braid goes to the ground side of your 75 ohms and the center
conductor to the hot side. A cheap jumper and chop off the connector on
one end will do the job for you on the FM side and another one with both
ends bolted on for the TV side..

The cheap {$9.99) RCA one is actually overkill for your application, I
think (unless your cable has stuff on it past 1ghz).
