Product Description
When a 10W booster no longer holds your 5.8GHz link together, this 20W signal booster provides the extra 3dB of margin that often makes the difference between stable video and a lost connection. Operating across the 5725-5850MHz band, it amplifies both the transmit and receive paths with 43dBm (20W) output, 20dB TX gain, and 18dB RX gain, keeping FPV video, telemetry, and point-to-point data links balanced at range. It runs on a 12-24V DC supply with SMA female connectors and a standard 5.5 × 2.1 mm power jack, all housed in the same compact 118 × 59 × 17 mm aluminum enclosure weighing just 0.2 kg—so it fits into existing setups without adding bulk.
Typical Applications
- Long-Range FPV Video: Extend 5.8GHz downlink range beyond standard VTX limits
- 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
The jump from 10W to 20W delivers roughly 3dB of additional link margin—which in the 5.8GHz band matters more than at lower frequencies, because obstacles and distance erode signal strength faster. The 43dBm transmit output pushes your video and data farther through open air and light obstructions, while the 18dB receive gain ensures weak return signals are amplified cleanly. This symmetry keeps two-way links balanced, which is essential for telemetry and remote control where a strong outbound signal is useless if the inbound path fails.
The wide 12-24V DC input accepts 3S-6S LiPo packs, vehicle electrical systems, and solar-charged battery banks, giving you flexibility in how you power the unit. The 5.5 × 2.1 mm jack is common in field equipment, and the SMA female ports connect directly to standard antennas and coax without adapters. The aluminum housing provides passive cooling and mechanical protection, and at just 0.2 kg the booster adds negligible weight to a drone or portable ground station.
Tuned for 5725-5850MHz, it covers the standard FPV channels and the broader 5.8GHz ISM allocation. If you've been running a 10W booster and still experiencing video dropouts or range limits, stepping up to 20W is a practical way to regain margin without changing your RF chain.
