Includes 1x QO-100 Bullseye TCXO LNB

This is a TCXO stabilized LNB for the QO-100 / Es’hail-2 geostationary amateur satellite and other Ku-band satellites. Manufactured by Othernet.

The Bullseye LNB is the world’s most precise and stable DTH/consumer Ku-band down converter. Even a VSAT LNBF costing hundreds of dollars more is no match for the performance of the Bullseye 10K LNB. Each unit is calibrated at the factory to within 1 kHz of absolute precision against a GPS-locked spectrum analyzer. Under outdoor conditions, the stability of the LNB is well within 10 kHz of offset. As a bonus feature, the  Bullseye 10K provides access to its internal 25 MHz TCXO through the secondary F-connector. This reference output can be used to directly monitor the performance of the TCXO over time.
