How To Connect A Yagi Antenna To A Cell Phone?

Yagi antennas are high-frequency capturing antennas and are the best signal boosters for every device that you connect with them. Yagi antennas are directional antennas, and they work best, and their direction is towards the reception tower. The antennas transmit and receive high-frequency signals because as they are specified for a single direction, their signal strength increases likewise.

Check the signal strength.

Before selecting a location for installing a Yagi antenna, you must test the signal strength for your Yagi antenna. You can use the signal strength by using a multi-meter. Typically the signal strength is measured in decibels. In your cell phones, there is a manual way of checking the signal strength. The 'test mode' of the cell phone would give you an idea of the exact signal strength in your area, suggesting whether a Yagi antenna is beneficial for you or not.

Selecting the location for installation

The best option for selecting a point for the installation of the Yagi antenna is the location that is closest to the reception tower. The signal strength would automatically be maximum for that specific spot. The best thing about a Yagi antenna is that it does not need to be grounded like typical antennas.

Working of cell phone signal boosters

The cell phone has its frequency signal boosters. But in some places, the cell phone cannot catch proper signal, so we need an external antenna to aid it. Yagi antennas are the best form of external antennas that are directional and captures the signals with maximum wavelength and frequency.

Working of cell phone signal boosters

Signal booster kits are installed in cell phones that amplify the signals caught by the cell phone. So if you add a Yagi antenna in the same direction as the reception Tower and you can help the signal booster kits of cell phones to catch the signals properly. However, these techniques work in a specific direction. Yagi antenna cannot be used for multi-directional signal reception.

A step by step guide for installing a Yagi antenna with your cell phone

Before going into the detail of the actual connection process, keep in mind that the alignment of the Yagi antenna is very important for the reception of signals. If your alignment is not proper, then you won't be able to receive proper signals on your cell phone. Following are some steps to help you through the installation process.

  • The first step involves the mounting and positioning of a Yagi antenna. As a Yagi antenna is directional, you need to place it in the horizontal direction, with its position being vertical. The location for capturing the signals should be kept in consideration likewise.
  • The Second step is adjusting the position of the Yagi antenna with respect to the reception Tower. You must choose the most direct path in a straight line between the reception tower and the Yagi antenna. Mount the antenna as high as possible so that there is no obscurity in its way.
  • The third step is connecting your phone with the Yagi antenna through a wireless adaptor and a coaxial cable.
  • The fourth step is to test the signal strength and position your Yagi antenna likewise. To test the signal strength, you can use the 'test mode' of your cell phone.
  • The last step is a realignment of the Yagi antenna with respect to your cell phone. Gently turn the Yagi antenna 10 degrees and then check your cell phone for calculating the signal strength. Keep turning your Yagi antenna in proper positioning at the place where you get maximum signal strength.

So, this is how a Yagi antenna is perfectly attached to the cell phone. A cell phone is a portable device, so we cannot connect it with the antenna through a cable as a wireless connection has been made, so there is no need for a coaxial cable. Then disconnect the external adaptor and coaxial cable from your cell phone, and your work is done.

Why your cell phone signals are weak?

The reason why you need an antenna is that the signals accessed by your cell phone are weak. There are certain factors that result in weakening the signal strength. The first and foremost reason could be the distance of your cell phone from the reception tower.

 If you are traveling or live at a distance from the transmission tower, then the signal strength is diminished. It shows that there is an inverse relationship between signal strength and distance. As the distance of reception increases, the signal strength from the transmitter source is decreased.

The second most important reason is the presence of obstacles and hindrances in the path of signals. There are two types of obstacles these are external or internal obstacles. External hindrances include trees, mountains, valleys, and buildings. Internal hindrances, on the other hand, include walls, doors, and bricks of buildings.

Why your cell phone signals are weak

Sometimes you are talking on the phone and cannot hear the other person's voice. You go outside or get close to the window in order to hear them better. The reason behind it is that there are many obstacles in the path of signals which bring a decline in the signal strength. When we reduce the obstacles, the signal strength is automatically improved.

An antenna works in the same way. As we mount the antenna high above the obstacles, there is a lesser chance of the signal dropping. It is because we have cleared the path of signals, so the signal reception is automatically improved.

What are reception boosters, and how they help Yagi antennas?

Along Yagi antennas, you can also take help from reception boosters to increase your signal strength manifolds. As Yagi antennas act as an external source for receiving the signals, the reception boosters are an internal source for enhancing those signals' quality.

The working of reception boosters is unique. When the signal is captured by a Yagi antenna, it moves through the reception booster, which amplifier is the signal with the help of a cellular repeater. The signal is rebroadcasted throughout the surrounding area of the cell phone.

The internal antenna attached to the cell phone captures those enhanced and amplified signals. It does provide you not only good quality audio and video calls but also quick internet surfing and better data downloading speed.

What is signal strength?

So, the question arises of what signal strength is and why it is so important for an antenna and a cell phone. Signal strength is typically defined as the electric field with reference to some point that is distant from the reception antenna. Signal strength can also be called as received signal level.

When we are talking on the phone, the phone converts your voice into electrical signals so that they are transmitted in the form of electric and radio waves. The person on the other side whom you are talking to is also using a phone. So, the internal or external antenna attached to his cellphone reconverts the electrical signals into sound waves.

What is signal strength

This conversion and reconversion of sound into electric and radio waves is stimulated by the presence of an external antenna, mostly a Yagi antenna which is highly directional.


So, if you are facing the issue of the signal drop with your cell phone, consider attaching a Yagi antenna with it to solve the problem.
