Orbital builds high performance, high quality low noise block downconverters (LNBs) for the satellite communications industry. Our satellite LNBs are available for C, X, Ku and Ka-band. Each unit is expertly engineered, hand-tuned and tested, and comes with specs that are unique to that individual LNB – actual measurements, not averages.

With Orbital, you get the latest technology, very low phase noise, excellent local oscillator (LO) stability and long-term reliability – in the smallest form factor possible.

Our frequency converters are used extensively in military VSAT, SATCOM-on-the-move, emergency services, aeronautical and Earth observation applications. We use only the highest quality components, so our LNBs can seamlessly meet the demands of high throughput satellites (HTS) and produce a consistently flat frequency response. They stand up to Arctic cold, Saharan heat and rainforest humidity – as well as shock, vibration, power surges and static discharge.
