  • antenna impedance?

    i'm building a home stereo using a car stereo (pioneer FH-X731BT)) , can i use the 300 ohm twin lean FM dipole antenna(210-020) soldered to a Motorola plug(090-455)?

    ​Car stereos don't use dipoles! All you would need is a single piece, single length of wire. However I'm unsure as to the length, but I'd try something like 5ft, straight up vertical. Obviously for best sensitivity impedance matching is desired, but in this circumstance you'll probably be just fine.

      Car stereos are typically looking for a 75 ohm impedance. You can stick a coat hanger in and will get some reception, assuming you have strong enough stations near you, but it won't be optimal. Look for a 75 ohm antenna, or us an impedance matching transformer.

        Been there - used an old fashion car stereo whip antenna.
        A Velleman K2622 Am/Fm Antenna Amplifier provided 22db gain and improved reception greatly.

          Boy and I made this dipole out of some left over copper tubing (don't ask) and coax. It works! Put it somewhere you can turn it if you want to take full advantage of the dipole construction.

            My wife says she is not willing to go outside and nudge the antenna so i'll go with whip and if necessary the Velleman amp.

              I never whip my wife. :<P

                Used a pivoting ( swivel base ) antenna; this allowed for DXing - reminiscent of an Olde time Rabbit Ear
