New Unit for 2022 now with USB-C and Power LED.

This is a cost effective SAW based 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. Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. This particular model is tuned for use with 430-440Mhz.


The LNA used is a MiniCircuits PSA4-5043+ which provides at least 19dB of gain @ 435MHz. To stop out of band intermodulation an 440MHz SAW bandpass filter, which has a 30MHz bandwidth is also present. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB.  

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