Stereo antenna connections

[loyalstokie]

I have an old Toshiba stereo that I want to connect and FM aerial to so that I can receive FM radio.

The antenna connections ones that screw down, trapping a wire and making the connection.

I want to use a length of co-axiel cable and connect an old TV aerial (analogue) to the other end.

My question is, do I connect the co-axial cable to the 75ohm or 300ohm connection.

Also, is the ground a common terminal for both the FM and AM aerials?

Thanks,

Dave.

P.S. If someone would tell me how to uploda a photo, I would be happy to do so.

75. Not aure if tv aerial is much good. Wont harm to try any connection tho

Yeah, when I plugged my radio into the tv socket (dual tv/fm socket) by mistake, it didn't get a signal.

You need a 300 Ohm - 75 Ohm balun adaptor/connector.

I would advise you get a roof or loft mounted mounted FM dipole aerial properly installed.

If you only have spade connectors on your tuner, then connect the coax cable (from the roof/loft aerial) to the balun. (you can get them in places like Maplins).

You could buy an indoor FM ribbon aerial (depending on whether you get strong reception) and just screw it's spade connectors to the FM screw connectors on your tuner.

I would always encourage people to get a decent aerial fitted if at all possible. A diagonally aligned FM half-wave dipole aerial on a roof mast will also do well for DAB if you use that in future.

TV aerials aren't designed for FM/VHF signals. They are designed for UHF frequencies. They are not optimum. (You'll get more signal from the lead than from the TV aerial itself!)

This Maplin balun can be used in reverse. Plug in the coax aerial feed to it and then connect the balun to your tuner's screw connectors with a short length of 300 Ohm ribbon cable.

Thanks for the replies.

I am right to assume that I wouldn't need a converter because the stereo can accept either?

I have plugged a modern Hi-Fi into the tv socket and got a signal when the other end was yet to be connected, so I know that will have some benefit.

At the moment I can only get an AM signal, so anything will be better than the FM signal I get now. Whether the improvenment is due to the actual aerial or the cable going to it doesn't matter to me.

Can I ask why you don't want to (or can't) connect a correct aerial?

A perfect reply with perfect advice and in English, a good start to my day!
