Product Description
The 1.4GHz (1420-1440MHz) band sits in the L-band and is used for a range of specialised applications—from UAV telemetry and satellite links to remote video and industrial monitoring. This 10W signal booster amplifies both directions of the link, delivering 40dBm (10W) of output with 20dB TX gain and 18dB RX gain. It operates on a 12-24V DC supply, uses SMA female connectors, and comes in a compact 118 × 59 × 17 mm aluminum enclosure weighing just 0.2 kg. Whether you're extending a telemetry link across a remote site or strengthening a satellite downlink, this booster adds reliable margin without adding bulk.
Typical Applications
- UAV Telemetry & Command: Extend bidirectional data links for long-range drone operations
- Satellite Communications: Boost ground-to-satellite and satellite-to-ground signals in the 1.4GHz band
- Remote Video & Surveillance: Maintain stable video feeds over long distances
- Industrial & Utility Monitoring: Reliable two-way telemetry for SCADA and remote assets
- Public Safety & Emergency Comms: Strengthen critical UHF links in challenging environments
- Aerospace & Avionics Testing: Provide additional output for system validation and field trials

Key Advantages
The 1.4GHz range is relatively narrow and less crowded than the main ISM bands, which makes it attractive for specialised links where interference is a concern. With 10W (40dBm) of output and 20dB TX gain, this booster extends the reach of your transmitter significantly, while the 18dB RX gain ensures that weak return signals are pulled in cleanly. The result is a balanced two-way link that holds up even when conditions are less than ideal.
Power flexibility is a strong point: the 12-24V DC input accepts everything from 3S-6S LiPo packs to vehicle electrical systems and solar-charged battery banks. The 5.5 × 2.1 mm power jack is common in field equipment, and the SMA female ports mate directly with standard antennas and coax. The aluminum housing provides passive cooling and mechanical protection, and at 0.2 kg the unit is light enough for drone mounting or pole installation.
Tuned specifically for the 1.4GHz band, this booster covers the narrow allocation used by telemetry, satellite, and specialised video systems. If you're working with equipment in this band and need more link margin without redesigning your RF chain, this is a straightforward way to get it.
