This is a cost effective wide band unit which give excellent performance gains.

All our preamps are compatible with most USB SDR Dongles such as the RTL USB, Airspy, Fun Cube. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB-C cable (Not Supplied - See related items for a suitable USB Type A to C Cable).

Bias-tee voltage input is 5V. Note: Unlike previous models, component supply issues mean bias-tee input voltage is 5V max.

This unit is a small filter and preamp designed to go between a software defined radio receiver and an antenna.

The LNA used is a MiniCircuits PSA4-5043+ gain at common frequencies:

High quality SMA female connectors are fitted for antenna input and radio output, a RED power indicator is provided.
