3G 15dBi Yagi Antenna with RG58 Cable (L-3Mtr) + N (m) ST. Connector

A 3G 15dBi Yagi antenna is designed to enhance the reception and transmission of 3G cellular signals. Yagi antennas are known for their high gain and directivity, making them ideal for boosting signal strength in areas with weak coverage. Here’s a detailed overview of this type of antenna:

Key Features

1. Frequency Range:

   • 3G Bands: Typically operates in the frequency range used by 3G networks, which varies by region. In most cases, this includes bands like 850 MHz, 900 MHz, 1700 MHz, 1900 MHz, or 2100 MHz. Ensure the antenna is compatible with the specific frequencies used by your 3G network.

2. Gain:

   • 15 dBi Gain: This indicates a high level of signal amplification. The 15 dBi gain provides a significant increase in signal strength compared to lower-gain antennas. This high gain is achieved through the antenna’s design, which focuses the signal in a specific direction.

3. Design:

   • Yagi Design:
     • Elements: The Yagi antenna consists of multiple elements, including a driven element, reflectors, and directors. This design focuses the signal in a particular direction, which helps in receiving signals from or sending signals to a specific base station or cell tower.
     • Directivity: The antenna has a directional radiation pattern, meaning it needs to be oriented correctly toward the signal source for optimal performance.
     • Construction: Typically made from metal elements mounted on a boom. It is designed to be mounted outdoors for the best performance.

Advantages

• High Gain: The 15 dBi gain significantly amplifies weak signals, improving both reception and transmission quality. This is especially useful in areas with poor signal coverage.

• Directional Focus: The Yagi design allows for focusing on signals from a specific direction, which can be useful for long-distance communication or improving connectivity with a particular cell tower.

• Improved Signal Quality: Enhanced signal strength and quality can lead to better data speeds and more reliable connections.

Typical Applications

• Home and Office: Used in areas with weak 3G signal coverage to improve reception and connectivity. Often installed on rooftops or external walls facing the signal source.

• Rural Areas: Helps in boosting the 3G signal in remote or rural locations where cellular coverage may be sparse.

• Mobile Networks: Useful for improving signal reception for mobile network base stations or for use in mobile network testing.

Considerations

• Alignment: Proper alignment is crucial for maximizing the antenna's performance. The antenna should be pointed toward the nearest cell tower or signal source.

• Installation: Typically mounted outdoors and may require a mast or mounting bracket for proper installation. Ensure the installation complies with local regulations and guidelines.

• Frequency Compatibility: Verify that the antenna supports the specific frequency bands used by your 3G network.
