Quick Answer
External antennas can significantly boost signal strength for point-to-point wireless internet, especially in off-grid areas where line of sight is critical. Boosting signal strength using external antennas can be achieved with the right equipment and setup.
Choosing the Right Antenna
When selecting an external antenna, consider the frequency band of your wireless device. For Ubiquiti’s long-range bridge, which operates on 5 GHz, a high-gain antenna is ideal. Look for antennas with a gain of 19-24 dBi (decibels-i) and a beamwidth of around 45°. This will ensure maximum signal strength and efficiency. Some popular options include the Ubiquiti LBE-5-23-HP and the 24 dBi 5 GHz Sector Antenna.
Positioning and Alignment
Proper positioning and alignment of the antenna are crucial for optimal signal strength. In general, place the antenna at the highest point possible, such as a rooftop or a tower, to reduce signal loss due to terrain. Ensure the antenna is facing directly at the receiver, with a clear line of sight. You can use a laser pointer or a compass to help align the antenna. Keep in mind that even a slight misalignment can result in significant signal loss.
Additional Tips and Considerations
In addition to choosing the right antenna and positioning, consider using a mounting system that can withstand harsh weather conditions. A sturdy mount will help ensure the antenna remains stable and secure. You may also want to consider using a directional antenna to focus the signal and reduce interference from other devices. When setting up the antenna, use a cable with the correct impedance to match the antenna and reduce signal loss. Finally, test the signal strength regularly to ensure the antenna is performing optimally.
