Re: Connect FM radio to CATV? |
|
|
I needed to cut that catv cable to the JVC unit and was astonished Modern
cables, or at least the one I have, have a sheath that is made up of a
silver foil plus a number of extremely fine copper wires around it. In older
cables I could twist the sheath wires and they formed a reasonable
conductor. Now, the result is crap. Back to the drawing board to find a
connector :-(

Hello experts,
I have a 20 y.o.Sony receiver and am able to receive radio stations
when I connect the two terminals of the cable across a 300 ohm
(clearly marked on the back of
the unit) antenna connector.
A friend has a compact JVC model FS-1000 hi-fi unit that has radio,
cd and tape
drives and it has 4 antenna connections. The A.M. antenna is
connected to one
pair of adjacent connections - say 1 and 2. The F.M.antenna is a 2'
piece of tiny
cable is connected to the 3rd connection and the 4th is free. The 3rd
and 4th are
adjacent connections. I tried to find a manual for the JVC but
failed. I could just
simply connect the CATV cable across 3 and 4 but would prefer to have
some info
before doing this.
Does anyone about the 3rd and 4th connectors? Are they intended for
an FM antenna and is there a standard resistor across them?
TIA

Just get a 75 ohm to 300 ohm adapter (balun), or otherwise get the signal
into those two inputs with bare wire. Usually, on those 4-connector
inputs,
2 adjacent are for AM, the other 2 are for FM. Because everything is so
cheap these days, there is no longer a 300 ohm balun internally. In
practive
it probably doesn't matter whether you use a proper balun or bare wire to
get it in there.
