The OGN filter and preamplifier is located between a software defined radio receiver and an antenna. With a SWA bandpass filter and a 16dB low noise amplifier (LNA), it stops out-of-band intermodulation for increased sensitivity. The LNA is located before the SAW filter. This model is tuned for use with 868 MHz.

There are two options for powering the unit. Either via a USB connection or via the bias tee. However, any mini USB cable can also be used to power the unit.

>>> Helium users: Device is a receive-only amplifier and not suitable for increasing transmit power. If transmitting through this unit as well, you will damage it - not covered by warranty. <<<
