Ubiquiti RD-5G30-LW-US 5GHz Directional Dish Antenna 2-Pack
Overview
The Ubiquiti RD-5G30-LW-US is a 2-pack of 5GHz directional dish antennas delivering 30dBi of gain per unit. This is the right antenna when you need to bridge long-distance point-to-point links—backhaul routes, ISP last-mile delivery, or multi-sector deployments where wired connections are impractical. The lightweight construction cuts installation burden and wind load on mast structures compared to traditional heavy-duty dishes, without sacrificing RF performance. Each unit weighs under typical heavier variants, making solo or dual rooftop installations faster and safer. The 2-pack configuration supports redundant paths or simultaneous multi-directional coverage from a single infrastructure investment.
Compatibility
The RD-5G30-LW-US integrates with Ubiquiti's Rocket M access points and compatible airOS-based radio modules across the 5GHz band. Deploy these antennas with standard 802.11ac and 802.11n protocols. The pairing works in point-to-point and point-to-multipoint topologies. Match antenna selection on both ends of the link for balanced link budget—a 30dBi dish pairs best with equivalent or higher-gain receive antennas to avoid asymmetric signal strength.
Installation Notes
The directional beamwidth is narrow, so precise azimuth and elevation alignment is critical. Even small misalignment (5–10 degrees) degrades throughput substantially. Use a spectrum analyzer or signal-strength meter during commissioning. Mount on stable structures; the lightweight design reduces but does not eliminate wind-sway effects on tall towers. Weatherproofing connectors and feed cables is mandatory in outdoor environments—standing water and salt spray accelerate corrosion at RF connections. Standard U-bolt mounts are typical; verify mast diameter compatibility before ordering mounting hardware separately.
