Product Description
When a 10W booster still leaves your link on the edge, the 1.4GHz 20W signal booster provides the extra 3dB of margin that often makes the difference between a stable connection and a drop-out. Operating across the 1420-1440MHz L-band allocation, it amplifies both transmit and receive paths—20dB TX gain and 18dB RX gain—so your command and telemetry links stay balanced even at extreme range. The 12-24V DC input, SMA female connectors, and 5.5 × 2.1 mm power jack make integration straightforward, while the compact 118 × 59 × 17 mm aluminum enclosure weighs only 0.2 kg, ready for drone, vehicle, or pole-mounted deployment.
Typical Applications
- Long-Range UAV Telemetry: Maintain stable bidirectional data links on extended missions
- Satellite Ground Links: Boost L-band uplink and downlink signals for reliable SATCOM
- Remote Video Surveillance: Keep video feeds clear over long distances and difficult terrain
- Industrial SCADA & Telemetry: Two-way data links for remote pipelines, utilities, and mining sites
- Public Safety & Border Operations: Strengthen critical UHF communications in remote areas
- Aerospace & Avionics Testing: Higher output for system validation and field trials

Key Advantages
Doubling the output from 10W to 20W yields roughly 3dB of additional link margin—a meaningful gain in real-world conditions where foliage, buildings, or atmospheric attenuation eat into your range. The 43dBm transmit power extends your outbound signal significantly, while the 18dB receive gain ensures weak return signals are amplified cleanly, keeping the link symmetric and reliable for telemetry and command channels.
The wide 12-24V DC input accepts power from 3S-6S LiPo batteries, vehicle electrical systems, or solar-charged battery banks, giving you flexibility in how you deploy the booster. The 5.5 × 2.1 mm jack is a common field standard, 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 1.4GHz band, this booster covers the specialised L-band allocation used by UAV telemetry, satellite links, and remote video systems. If you’ve been running a 10W unit and still experiencing dropouts at range, stepping up to 20W is a simple, effective way to add margin without changing your entire RF chain.
