Has anyone here had luck using a leaf style OTA antenna on a stereo receiver for FM radio reception?


*I would try it out first myself but the Yamaha 671 reciever is at my camp and I need to be able to use it for FM radio this weekend. I can't get a regular FM antenna through Amazon in time without paying extra freight. Would like use one of my OTA antennas I already have there if it would work . TIA

Yes, just run the coax line from the antenna to the FM antenna jack on the back of the receiver. You may need a 75ohm connector/converter to screw onto the end of the coax cable which then slides onto the 75ohm coax jack on the receiver as some are not threaded.

I'll take a pic of mine and post it in a few minutes so you can see what I am talking about.

Here are some pics to help see what I mean...


This is the end of the coax cable and the coupler that screws on to the coax...



This is a pic of the coupler screwed on...



And this is a pic of it connected to the 75ohm coax jack on the back of the tuner (probably a receiver in your case)...




The coupler does not need to be screwed on to the receiving post on the receiver--it just slides onto it and is held on by tension.

The other end of the coax, in my set up, is connected to giant antenna in the attic. On a good night, I can pick up AM stations 8 states away.

FM comes in crazy clear!

You may be able to find that coax slide connector at Best Buy, if not, try a local hifi shop if you have one. I don't remember where I got mine as it has been years.


Hope this helps.

It might not be so simple. Some of the amplified antennas have a FM filter in the amp section which is usually passive and thus still works if the power is cut to the amplifier. Unless you can verify the specific antenna passes FM it could be a crap shoot.

You can build a 5/8th wave folded dipole antenna with a few feet of speaker wire like the ones usually supplied with receivers. The ones that look like a T made of wire. You can google FM dipole antenna DIY.

Or even just a 6-10 ft piece of small gauge single conductor wire. For a down and dirty antenna, you don't even need to terminate it into a coax fitting. Just poke a stipped end of the wire in the center hole in the receivers coax input. Depending on the gauge you might have to fold it over.

Meant to ask are those Sound Path Ultra cables? At first I thought they were Audioquest but then it hit me they have the SVS jacket on them but they might not be the only ones that use it.

Smaller gauge is an SVS sub cable
Larger gauge is a Pangea power cord
