The two most commonly used types of antennas for cell phone signal boosters are directional and omnidirectional antennas.
· Directional antennas are designed to focus the signal in a specific direction, which makes them ideal for areas with poor reception. They are also known as "yagi" antennas. Those directional antennas are mainly including:
n Yagi antenna, widely used as receiving antenna.
n Log periodic antenna, gain from 9dBi to 11dBi, widely used as receiving antenna.
n Indoor or outdoor directional panel antenna, gain from 7dBi to 10dBi, widely used as service antenna.
n Directional sector antenna, gain from 12dBi to 20dBi, widely used as receiving antenna or service antenna, installed with high power repeater system.
· Omnidirectional antennas receive signals from all directions, which makes them a good choice for areas with good reception. They are also known as "whip" antennas. the antennas are mainly including:
n Indoor omni ceiling antenna,gain 3~5dBi, widely used as service antenna.
n Outdoor omnidirectional antenna,gain 3-5dBi, widely used as receiving antenna.
The type of antenna you need will depend on the specific situation. If you have poor reception in a particular area, you will need a directional antenna.
Here is a table that summarizes the key differences between directional and omnidirectional antennas:

Receives signals from all directions
In addition to the type of antenna, you also need to consider the frequency range of the antenna. Cell phone signals operate in a variety of frequencies, so you need to make sure that the antenna you choose is compatible with the frequencies that are used in your area.
The frequency range of a cell phone signal booster antenna is typically between 700 MHz and 2100 MHz.
If you are unsure about which type of antenna or frequency range is right for you, it is best to consult with a professional. They can help you choose the right antenna for your specific needs.
