Without antennas, you will not receive any signal. Well, you might get some radio stations that work but the signal will be so poor that you will not hear anything clearly. AM and FM antennas are helpful in this regard.

The former modulates the carrier while the latter regulates the frequency. Although FM has a better noise cancellation effect, both techniques are important for the best sound quality. That said, here are 7 of the best AM FM car radio antenna that can work at home too.

Key Considerations to Make When Purchasing an AM FM Radio Antenna

Best AM FM Antennas

The main cause of scrambled signals is obstructions. Dense populations, rough terrain, and high buildings are examples of such obstructions that may interfere with a radio signal. In order to choose an antenna that overcomes these obstructions, you will make three important considerations:

back to menu ↑

The Population in Your Area

Getting a direct signal in an area that is densely populated can be troublesome. If you realize that you live in an area surrounded by a lot of people, you should choose an antenna that prioritizes sharp directivity over high gains.

In other words, you need a direct connection to the source of signals, instead of collecting all signals available around you.

For best results with antennas, you should pick a location that allows you to access the direct signal with minimal interference from reflected signals. However, this may not always be possible because you choose where you live based on other more important factors. Therefore, opt for antennas that have sharp directivity.

The Antenna’s Beam Width

When multiple signals use the same path, audio will be distorted. In most cases, unwanted signals may bounce off obstructions and interfere with the signal you are receiving on your radio. While you cannot always avoid obstructions, you can reduce interference by buying the right antenna.

Some antennas will filter out unwanted signals and leave you with the audio you desire, while others will span a wide selection of signals and boost their clarity to improve your listening experience.

The best indoor FM radio antenna is one that is able to reject all disruptive signals and focus on those you want to receive on your radio. In order to do this, the antenna’s beam must be narrow.

back to menu ↑

The Antenna Type

There are usually three types of antennas, each suited for a different purpose. The type you choose depends on your location and signal needs.

If you are in an area with many obstructions, you want an antenna that prioritizes a direct signal. At the same time, if you want to listen to multiple radio stations, you will look for one that has high gains and covers a wide area.

Type 1: FM Antennas

Often referred to as broadband antennas, these usually pick more than one signal. As a result, they might not modulate all frequencies. However, they work perfectly for receiving signals for local radio stations.

back to menu ↑

Type 2: Integrated FM Antennas

All radios come with an antenna that is built into their hardware. When you live in an area that is free of interference, this antenna is sufficient. However, any slight obstruction can turn into an inconvenience as it scrambles most signals. This is because such antennas cannot handle multiple signals at the same time.

Type 3: Rotator

Tired of listening to the same radio station every day? What you need is a variety of signals that are clear enough to listen to. To get this, you should install a rotator.

Rotators are used along high gain antennas in order to collect all signals that are available within 200 miles. While you will not have a guarantee that every single signal you receive will be crystal clear, you will definitely have more than one radio station to listen to.

Frequently Asked Questions About FM Antennas

indoor tv antenna

It may seem like a very straightforward process, but buying and installing antennas can get quite complicated. Here are the answers to all the questions you may have about this process:

back to menu ↑

What Is FM Interference?

Due to obstructions and the distance between the transmitter and the antenna, some FM transmissions may get scattered. This phenomenon can cause you to receive new signals that you had not received before, but it may also disrupt the signals you have been receiving and cause radio stations to disappear.

back to menu ↑

What Is the Difference Between Outdoor and Indoor FM Antennas?

As the name suggests, outdoor antennas are installed outside while indoor antennas are used in the house. An outdoor antenna is highly directional and receives signals easier than the indoor one. One the other hand, indoor antennas are convenient when the outdoor installation is not possible. They can also be amplified for greater sensitivity.

How to Connect FM Antenna to Receiver?

It is necessary to connect your antenna to the receiver in order to pull better signals to your stereo. You will need a screwdriver and your FM antenna. Follow the steps below in order to connect the two:

  1. Loosen the FM ANT screws on the receiver.
  2. Wrap each of the two antenna wires to a single metal post under the screw heads.
  3. Use a screwdriver to tighten the connection.
  4. Place the antenna near a window to get clear signals.

Final Take

When you finally buy that stereo you have always wanted, it is only right that you get the clearest sound from it. While you can always rely on the in-built antenna to serve its purpose, there is always a chance that it won’t be as clear as you hoped. Depending on where you live, getting a clear signal may be almost impossible. This is why you need to buy the best AM FM antenna.

The best antenna is one that rejects all deflected signals and focuses on those that you wish to receive. It should be able to boost the clarity of sound and have minimal interference from the unwanted transmission.

With this comprehensive review of 7 good antennas you can buy online, you are likely to make the best purchase. Whether you decide to buy the Antop amplified antenna or the Omnidirectional outdoor FM antenna, you now know the pros and cons of each.
