Orbital Ku-Band Modified Series LNBs
Orbital Low Noise Block Downconverters
Our LNB is protected from man-made conditions such as shock, vibration, low power,
over-voltage, surges, transients, and static discharge. Performance is consistent and replacements will match or exceed your original device. Market leading specifications yield some of the best phase noise on the market.
Ku Band PLL LNB
40 to 65 dB gain, 250 to 1050 MHz bandwidth, any Ku satellite
Orbital Flexibility
Orbital can use its expertise to customize standard product to fit unusual requirements. Custom connectors, LOs, bandwidths, and frequency modifications are available.
"Mass-Custom" Solution
Orbital starts with a proven performance product that is extremely well engineered with the development costs amortized over hundreds of thousands of units and the parts costs reduced by volume discounts. We then customize the mass produced LNB into what you want at 1/100 the cost of designing and building from scratch.
- Custom Frequencies
- Any Connectors
- Dual Power Option
- Special Color
- Private Labeling
- Rack Mounting Option
Enhancing Standard Product
Mass production means low-cost, reliable, repeatable products. Engineers design these products well within margins on component specifications so that individual tuning is not required to meet desired specifications.
As we modify product, we also tweak the design and components to optimize them for their inherent capabilities. Effectively, we bring out the full potential of the product by adjusting components to their full capability.

Loss of Lock Alarm – LOLA (optional)
LNBs can lose oscillator lock from internal failure or loss of the 10 MHz reference. The LOLA detects this anomaly and increases the current consumption of the LNB over the IFL cable to trigger a redundant switch or other detector. No extra ports, cables or infrastructure are required.
Simply hookup the LNB with 10 MHz present, set the current windows on the redundancy system so they are just out of triggering, then turn off the 10 MHz to trigger the LNB LOL circuit. The redundant switch should activate. Restore 10 MHz and the LOLA will reset.
It should be noted that these LNBs are exceptionally good for 10 MHz lock range. They will stay locked under adverse 10 MHz conditions and keep the system in sync.
