External Reference LNBs require a 10 MHz reference and Orbital 10 MHz Oscillators fill the bill.  They are manufactured specifically for satellite applications - satellite applications require very low phase noise, an attribute not generally found on GPS systems.  The Orbital MOM - Master Oscillator Module  and POP - Precision Oscillator Package are a base of a great family of Oscillators.

A common request is for always on oscillators, so that if the unit is one of a redundant set, it instantly locks on frequency.  Another is for external DC, and BDC units in stock generally have these options.

Dual power and alarm reporting are less common options that we are happy to comply with - but these are not common options, however, so stock units are not generally configured for this.
