How to Boost FM Radio Signals?

You are so attentive listening to your favorite radio program, trying to enjoy every piece of it and suddenly your radio signal breaks and then your radio begins to emit irritating noises. Definitely, you will get annoyed and sometimes frustrated because you will certainly miss the interesting part of the broadcast.

Probably, you have been searching for a way to boost your radio signal to avoid this heartbreaking situation so that you can enjoy your favorite radio program (s) wholeheartedly. 

Its common knowledge that radio signals are the main feature that are responsible for the working of a Radio, and we will explain and give steps on how to deal with the issue.

What are Radio Signals

Radio signals or radio waves are a form of electromagnetic wave. Although this may sound complicated, it is possibly sufficient to say that these waves have both electric and magnetic components. They are the same as light rays, ultra-violet and infra-red. The only difference is in the wavelength of the waves.” Source: Wikipedia

The above text is just technical jargon for saying that radio signals are wavelike particles like light that transmit energy and information. Understanding this concept will help you understand why radio signals can have issues as wave particles can be blocked or superimposed.

Steps to Boosting FM Radio Signals

Step 1: Get rid of any material that would interrupt your radio signal:

Enormous objects can stand on your way to achieving a good and reliable radio signal. Therefore, ensure you remove them before tuning in your radio.

Step 2 : Switch to FM mono: 

A radio can either operate on mono or stereo signal. A stereo signal is good but in hard times switching from stereo to mono can help you achieve a better signal. Unfortunately, some radios don’t have this feature. You should note that some radios have this feature in the form of a button, while some, when there is network failure they switch to mono automatically.

Step 3: Switch off or dispose close by electronic devices:

When some electronic devices are on, near your radio, it can interfere with the signal. You can switch them off or transfer them to another area far from the radio. Some of the devices that interfere with a radio’s reception are phones, computers, etc.

Step 4: Check your antenna:

Similarly, to some insects, the antenna is the signal reception point of a radio. Without the antenna, your radio can not receive signals. So you must ensure your antenna is in good shape. A dipole antenna is the best signal receiving antenna. It has two sections for receiving signals from two different locations. Make sure you stretch out the two antennas completely. However, this dipole antenna doesn’t come with all radio. 

Ensure the antenna cables are in good shape. Sometimes the fault can come from the outdoor or indoor antenna. Its cables might have spoilt or rusted due to harsh weather conditions, or it might be bitten by some animal. Para venture the cables have spoilt replace them with 18AWG RG6 cables. They are one of the best antenna cables that are durable. Also, it is important to mount your outdoor antenna on the roof top or on top of your attic. Remember to always place your radio on the window and face its antenna towards the outside.

Step 5: Relocate:

Sometimes we find ourselves in a location where there is poor signal reception and we are in serious need of signal for making an urgent call or sending a text so we begin to move from one spot to the other waving our phones around in search for signal. Apply this same technique to your radio. Signals differ from one spot to the other. You are in a room and there is no signal there, leave that room and move to the next. The signal might be much better there.

Step 6: Get a signal amplifier:

Signal amplifiers boost your radio antenna’s ability to receive signals. All you have to do is buy it and connect it to your antenna.

Step 7: Buy an attenuator (adapter):

An attenuator is a device that decreases the strength of a signal without interrupting its quality signal emission. It helps to decrease the amplitude of signals that might interfere with your radio signal.

Step 8: Change your antenna:

An old or worn out antenna can never serve you better. 

Step 9 Get an outdoor antenna:

Indoor antennas are very effective, but if you live in an area where the signal reception is horrible, an outdoor antenna would be a great boost to your radio signal. So if you lack it, go and buy it.

Factors that contribute to poor radio signal

Some of the reasons your radio keeps on having signal failure are:

  1. Using a radio in a location that is so far from a station transmitter, would suffer from poor signal
  2. Enormous objects like tall buildings can interfere with a radio signal. If you live in a city, you are likely to face a poor radio signal.
  3. Construction materials like metals, aluminum, etc. used to produce home building materials can contribute to poor radio signal.
  4. An antenna that can receive signals from one location at a time would eventually contribute to poor radio signals.
  5. If you have more than one radio and they are sharing one outdoor antenna, this could be the problem.

Best FM radio antennae

An antenna is a device responsible for signal reception. For your radio to receive any signal, it is through the antenna. Therefore, it is a compulsory part of a radio. Before purchasing an antenna, there are three necessities you must consider. They are:

  • Impedance: The impedance of an antenna is the first thing to always put into consideration. The impedance of an FM Antenna must be equivalent to that of the FM radio. If it doesn’t match, signal reception cannot occur. Impedance is measured in ohms.
  • Frequency Range:  The frequency range determines how good an antenna can send and receive signals. Antennas with a high frequency range can collect signals from far locations than an antenna with lower frequency. Frequencies vary from 80 to 100 MHz, 88 -108 MHz and many others.
  • Cable length: Long antenna cables that are 10 feet can be comfortably mounted anywhere that signal reception is found. But Antennas with shorter cables are limited and can’t be mounted far from the radio.

Conclusion

After you have followed this guide faithfully and have tried your possible best but still facing this poor signal challenge. Then the problem is from the antenna. Antenna can develop a fault that you might not detect on your own, so consider calling a professional to check your antenna and correct any faults. It is not really safe for you to self-check and repair your antenna because you may detect a fault that is not actually the fault, thereby causing more damages to it except you are an antenna repair expert yourself.

That concludes the guide on how to successfully and efficiently boost your FM radio Signals.
