Q
What is a Ubiquiti antenna?
A
A Ubiquiti antenna is a high-performance RF device designed to transmit and receive wireless signals in Ubiquiti airMAX and UniFi networks with optimized gain and beamwidth.
Q
What types of Ubiquiti antennas are available?
A
Ubiquiti offers omnidirectional, sector, and highly directional point-to-point antennas to suit coverage, distance, and interference requirements.
Q
How do I choose the right Ubiquiti antenna for my network?
A
Select your antenna based on coverage area, link distance, environment, and required gain—sector for area coverage, directional for long-range links.
Q
What does antenna gain mean and why is it important?
A
Antenna gain (dBi) measures signal amplification and directivity; higher gain focuses energy for longer links but narrows beamwidth.
Q
How does beamwidth affect Ubiquiti antenna performance?
A
Beamwidth defines the antenna’s coverage angle; narrower beamwidth extends range and reduces interference while wider beamwidth covers larger areas.
Q
Are Ubiquiti antennas compatible with third-party radios?
A
Ubiquiti antennas are compatible with any 2.4 GHz or 5 GHz radio using the same connector and impedance but deliver optimal performance with Ubiquiti radios.
Q
What frequency bands do Ubiquiti antennas support?
A
Most Ubiquiti antennas support 2.4 GHz and 5 GHz bands; select dual-band models for flexibility or single-band for optimized performance.
Q
What is the typical range of a Ubiquiti point-to-point antenna?
A
Range varies by model and environment; high-gain directional antennas can achieve reliable links up to 50 km under clear line-of-sight.
Q
How do I properly install a Ubiquiti antenna?
A
Mount on a stable mast with clear line-of-sight, secure N-type connections, align precisely, and weatherproof cables with sealant.
Q
How do I align a directional Ubiquiti antenna for optimal signal?
A
Use the onboard LED signal meter or Ubiquiti AirControl software to fine-tune azimuth and elevation until RSSI peaks.
Q
Are Ubiquiti antennas weatherproof?
A
Yes, Ubiquiti antennas are engineered to IP67 standards, ensuring full dust protection and water immersion resistance.
Q
What mounting hardware is required for Ubiquiti antennas?
A
Most models include adjustable pole-mount brackets; ensure you have the correct pipe diameter and stainless-steel hardware for corrosion resistance.
Q
Can I use Ubiquiti antennas indoors?
A
While designed for outdoor use, you can deploy Ubiquiti antennas indoors, though performance may be reduced by walls and interference.
Q
What maintenance do Ubiquiti antennas require?
A
Periodically inspect mounts and connectors, clean radomes with mild detergent, and re-seal weatherproofing as needed.
Q
What is MIMO technology in Ubiquiti antennas?
A
MIMO (Multiple Input Multiple Output) uses multiple spatial streams to increase throughput and resilience to interference.
Q
Which cable and connectors work best with Ubiquiti antennas?
A
Use low-loss LMR-400 or equivalent coax with N-male to N-female connectors to minimize signal attenuation.
