The Othernet Bullseye LNB is a down-converter for reception of the Oscar 100 amateur radio and those in the Ku band. The Bullseye is one of the most stable and precise LNB to date. It does not need to be modified to receive the narrow or wide QO-100 transponder.
Each Bullseye is calibrated at the factory at 1kHz with a spectrum analyzer locked by GPS.
In normal outdoor use (25°C), the frequency offset is less than 10 kHz thanks to its integrated 2ppm TCXO* (see more below) and a 25 Mhz reference.
A second output F (red) is available to benefit from the 25 Mhz reference signal output in order to control another device or to check the stability.

* The TCXO has an initial offset of 2 ppm, but other variables affect the total offset you can get. There is the stability related to the temperature variation which can add an additional 2 ppm and the TCXO which adds an additional 1 ppm offset per year. For applications that require ultra stability and precision over time, we recommend using a GPSDO instead.
