Product Description
The 5.8GHz (5725-5850MHz) band is the standard for FPV video and a workhorse for point-to-point wireless links, offering cleaner spectrum and wider channels than 2.4GHz. But higher frequencies mean faster signal loss—so when a standard transmitter starts to fade, this 4W signal booster restores the link. It amplifies both directions of the connection with 36dBm (4W) output, 18dB TX gain, and 18dB RX gain, keeping video, telemetry, and data streams stable at range. Power comes from a wide 6-16V DC input, and SMA connectors mate directly with your antennas and coax. The compact 64.5 × 34.5 × 12 mm aluminum enclosure weighs just 70g, making it easy to mount on a drone, pole, or portable ground station. The 2.5 × 0.7 mm power jack is common in compact field equipment.
Typical Applications
- FPV Video Downlinks: Extend 5.8GHz video range for long-range FPV and drone operations
- UAV Telemetry & Control: Maintain stable bidirectional links on extended missions
- Wireless Backhaul & Bridges: Boost point-to-point links for campus, rural, and industrial networks
- Public Safety & Surveillance: Reliable two-way video and data links in remote or obstructed areas
- Industrial IoT & SCADA: Two-way data transmission for remote sensors and controllers
- Amateur Radio & Field Testing: Higher output for licensed 5.8GHz experimentation

Key Advantages
With 4W (36dBm) of output and 18dB of gain on both the transmit and receive paths, this booster keeps two-way links balanced—so you're not just transmitting farther, you're receiving weaker return signals cleanly too. That symmetry is essential for telemetry, command, and data applications, where a strong outbound signal means nothing if the inbound path drops. The 6-16V DC input accepts a wide range of power sources, from small LiPo packs to vehicle electrical systems, making it easy to integrate into portable and mobile setups.
The SMA connectors mate directly with standard antennas and coax, and the 2.5 × 0.7 mm power jack is common in compact field equipment. The aluminum housing provides passive cooling and mechanical protection, while the 64.5 × 34.5 × 12 mm footprint and 70g weight make it small and light enough for drone mounting or pole installation. No extra bulk, no unnecessary complexity.
Tuned specifically for 5725-5850MHz, this booster covers the standard FPV channels and the broader 5.8GHz ISM allocation used worldwide. If you're fighting range limits or video dropouts on 5.8GHz, this is a straightforward way to add margin without redesigning your RF chain.
