Build An Fm Transmitter Antenna

Portable satellite receivers let you listen to music through your car's FM radio by using a built-in FM transmitter. You can make an FM transmitter antenna, which will amplify and boost the FM transmission capabilities of the satellite radio's FM transmitter. This will provide a better signal for hearing the music being transmitted. You will need a few parts from an electronics supply shop and expertise in using a heat gun and soldering iron. The satellite radio must have a plug to accept an FM transmitter antenna or the antenna cannot be used.


Instructions


1. Unscrew the back off the phone plug. Unwind some copper wire from the copper wire spool. Strip a half inch of insulation off the end of the copper wire with the wire strippers.


2. Push the end of the copper wire through the hole in the bottom of the back of the phone plug.


3. Heat up the soldering iron for two minutes. Solder the end of the copper wire to the inside metal lug attached to the phone plug. Let the solder cool for a minute.


4. Cut a piece of heat shrink tubing that is about the same length of the metal lug with the utility knife.


5. Put the piece of heat shrink tubing over the metal lug. Hold the heat gun over the heat shrink tubing. Turn on the heat gun.


6. Turn off the heat gun after a minute has gone by.


7. Screw the back of the phone plug back onto the phone plug.


8. Measure two feet of copper wire from the back of the phone plug. Cut the copper wire from the copper wire spool at the two-foot mark with the wire cutters.


9. Plug the phone plug into the phone plug connection on the portable satellite radio.
