40–80 km High-Gain PTP Links

The 1.8 m RP-SMA Dish 2-Pack is a complete high-gain dish antenna solution built for long-range point-to-point (PTP) backhaul using RP-SMA connector radios from Ubiquiti, Cambium, and Mimosa and includes RP-SMA jumper cables. These antennas offer the appropriate gain for 40–80 km links and provide strong antenna performance with a narrow beamwidth to improve signal stability and throughput for rural broadband, enterprise connectivity, and other reliability-critical deployments.

Narrow Beamwidth and SNR Advantages

Engineered to provide optimal gain for high signal quality in low-noise environments, these antennas ensure reliable link performance and consistent throughput over long distances. The narrow beamwidth minimizes noise interference, enhancing SNR and maintaining stable performance on longer paths.

Durable, Low-Maintenance Performance

The sturdy dish design ensures stable alignment and consistent operation even in variable weather conditions. When properly installed and periodically inspected, it provides reliable long-range point-to-point throughput for years with minimal maintenance and a lower total cost of ownership.

Direct RP-SMA Connection for Ubiquiti, Cambium, and Mimosa Radios

RP-SMA connectors attach directly to compatible Ubiquiti, Cambium, and Mimosa radios to eliminate conversion loss. This direct attachment simplifies installation, reduces connection losses, and helps maintain stronger end-to-end link performance.

Simplified Installation

The RP-SMA interface connects directly to compatible Ubiquiti, Cambium, and Mimosa radios, making it a straightforward antenna option for RP-SMA connector deployments. Direct connection reduces unnecessary interconnects and potential points of failure, improving reliability and streamlining field deployment for WISPs and integrators.

Remote Relay Sites

With a high front-to-back ratio, the 1.8 m dish reduces unwanted signals from behind the antenna, making it ideal for remote relay sites and other low-interference locations where cleaner RF conditions are easier to achieve. It lacks a shroud and isn’t a deep-dish design, which can produce more noticeable 90° side lobes. Thoughtful placement and adequate separation from nearby antennas can help minimize interference, so it’s best suited for installations that aren’t densely collocated on crowded towers.

Lightweight and Easy to Deploy

Each box contains two 1.8 m dishes, making shipping more cost-efficient. The low-profile design without a shroud or radome keeps the antennas lightweight for easier handling and installation, helping simplify backhaul deployments.
