Product Description
The 2.4GHz (2400-2485MHz) band is the world's most heavily used ISM frequency, powering everything from Wi-Fi and Bluetooth to drone control links and industrial IoT networks. Its popularity is a strength—but it also means congestion, and congestion shortens range. This 20W signal booster tackles that problem head-on, amplifying both directions of the link with 43dBm (20W) of output, 20dB TX gain, and 18dB RX gain. Powered by a 12-24V DC input, it uses SMA female connectors and a standard 5.5 × 2.1 mm power jack, all housed in a compact 118 × 59 × 17 mm aluminum enclosure weighing just 0.2 kg. Where a 10W booster no longer holds the link, this unit adds roughly 3dB of extra margin—often enough to turn a marginal connection into a dependable one.
Typical Applications
- Long-Range UAV Control & Telemetry: Keep command and data links stable on extended missions
- Wi-Fi Backhaul & Outdoor Bridges: Boost point-to-point links for campus, rural, and industrial networks
- FPV Systems in Noisy Environments: Cut through interference for reliable 2.4GHz video and control
- Industrial IoT & SCADA: Two-way data transmission for remote sensors, PLCs, and controllers
- Public Safety & Emergency Response: Strengthen critical 2.4GHz links in obstructed or remote areas
- Amateur Radio & Field Testing: Higher output for licensed 2.4GHz experimentation and validation

Key Advantages
Doubling the output from 10W to 20W yields roughly 3dB of additional link margin—a real advantage in the 2.4GHz band, where interference from nearby Wi-Fi networks and other devices constantly chips away at usable range. The 43dBm transmit power pushes your signal farther and more reliably through obstacles, while the 18dB receive gain ensures weak return signals are amplified cleanly. That symmetry is essential for control and telemetry links, where a strong outbound signal is worthless if the inbound path fails.
The wide 12-24V DC input makes this booster easy to integrate into a variety of power setups, from 3S-6S LiPo packs to vehicle electrical systems and solar-charged battery banks. The 5.5 × 2.1 mm power jack is a common standard in field equipment, and the SMA female ports connect directly to your existing antennas and coax without adapters. The aluminum housing provides passive cooling and mechanical protection, and at just 0.2 kg it adds negligible weight to a drone or portable ground station.
Tuned for the full 2.4GHz ISM band, it covers all standard Wi-Fi channels, drone control frequencies, and the broader allocation used worldwide. If you've been running a 10W booster and still experiencing dropouts, interference, or range limits, stepping up to 20W is a practical way to regain margin without changing your entire RF chain.
