I would like to buy an FM antenna for a Yamaha RX-V870 receiver that you "push in" to the FM antenna port on the back of the receiver. Next to the antenna port it says 75ohm unbalanced and when I stick my finger into the port, it has a pin in the middle, just like a coaxial cable does that you plug-into the back of a television. There are two 75 ohm FM antennas on Amazon that I am interested in. One has an F style male connector (with the pin in the middle) the other is a PAL connector. The reviews of the F style male connector says it works on Yamaha receivers, but how would the F style male connector and the antenna port "match up" if they both look the same, pin connecting to pin? I'm not technically savvy so I apologize if this question seems funny.
