An FM radio transmitter is a great device that allows anyone to listen to his or her favorite music playing on an iPod or any other audio device wirelessly, even at a great distance from the audio player. However, there are certain factors that can lessen the signal strength and reception of the radio signal transmission. Personal FM radio transmitters have a limitation when it comes to broadcasting radius. Even so, the signal can still be strengthened to provide access to music even when driving away from the home or from the transmitter. Here is how to boost your FM radio transmitter.
Step 1 – Choose an Unused Frequency
Do not choose radio frequencies that are being used by local radio stations. Since local radio stations use more powerful transmitters, it will always bleed through the personal FM radio transmission. Choose a radio frequency that is not being used or one that is way below or above local radio station frequencies. This will definitely boost the personal transmitter’s performance.
Step 2 – Correctly Position the Transmitter
Make sure that the FM radio transmitter and the car’s antenna does not have any obstruction. Solid obstructions decrease the signal coming from the transmitter and will, therefore, affect the car stereo’s reception. If necessary, move the car in a position where the FM radio transmitter’s signal is strengthened.
Step 3 – Reduce or Remove the Antenna on the Receiver
Usually, some transmitters only work on a few fixed frequencies. If a radio signal coming from a local radio station is interfering with the signal coming from the transmitter, reduce the length of the car’s antenna or remove it. This will probably reduce the interference and boost the transmitter’s signal. Better yet, make use of directional antennas that allow the transmitter and the receiver to work in harmony.
Step 4– Upgrade
If the FM radio transmitter still produces a weak signal, it is best to upgrade to a more powerful unit. Transmitters are only as powerful as they are designed to be. Go to the electronics shop to purchase an FM radio transmitter that can produce more powerful signals and better quality sounds. Such transmitters will work the same way as the old one, but only with more improved signal strength. This is ideal for those who are living in areas where other frequencies are being used by radio stations or other similar facilities.
Step 5– Build an FM Radio Transmitter Antenna
An FM radio transmitter antenna will definitely boost the transmission capabilities of the transmitter. However, check if the transmitter has a plug to accept the antenna first before deciding to install one. If not, purchase a transmitter with such a plug. The antenna can be built from simple copper wire and installed to the plug on the transmitter.

Having an antenna for the transmitter will definitely make the signal transmission stronger.
