BB75 Ku/Ka Dual-Band

We have more than 25 years of experience and expertise in design and manufacturing stabilized satellite antennas with excellent performance in radio frequency and tracking capabilities, mainly for professional and recreational maritime use, for land mobile hi-end, military and law enforcement.


Introducing the brand new BB75 Ku/Ka Mark II
for Global Superfast Internet.

BB75 Dome 2 BB75 Coverage
Product Info


Ku and Ka VSAT band are finally combined into one single high-performing integrated antenna, compounding two universes for higher speed and better coverage.
The all-new BB75Ku/Ka antenna is designed for yachts and professional Oil&Gas, ferries and commercial ships willing to harvest the 50 Mbps download speed offered by Ka band satellites, while relying on the coverage offered by Ku band networks.
The BB75Ku/Ka benefits from an innovative beam and band switching technology, allowing quick and automated commuting among available Ku and Ka satellites globally. An intuitive screen app manages network preferences, coverage areas and security features.


The challenge of a dual-band antenna in a limited space has been solved by using entirely custom-designed parts, realized by extensive research in dielectric and coating materials, with hundreds of hours of computer simulation and tight-tolerance machinery.
The antenna is equipped with two independent RF groups for the Ku and Ka band sharing through the same ultra-efficient coaxial feed.
The compact 75 cm carbon-fiber dish is treated with a tuned multi layer composite structure, which vastly improve its RF efficiency. The dish is mounted over a 3-axis chassis 100% made with aeronautical grade aluminum.
The tracking is managed by state-of-the-art software and high-precision inertial sensors that exclude the need for an external gyro, resulting in superior tracking performance in any weather.
An innovative “super-tuned” radome was specifically designed to reduce losses and the depolarization effects especially in Ka band.


The mechanics guarantee a wide working range, with -20/+100 degrees in elevation and +/- 30 degrees in roll to allow uninterrupted operation at northern latitudes and/or in rough sea. Structural and vibration analysis inherited from Oil & Gas and Military operations was employed to guarantee maximum stiffness of the structure.
All electronic components, including the antenna controller unit (ACU), the Ku and Ka band satellite modems and the routing logic are embedded inside the dome, allowing for a simple and hassle-free installation: a single technician in less than five hours thanks to reduced weight, compact design and the need to connect two cables only (Ethernet and power).


Special care in the use of multi-spot beam HTS was embedded in the software design. Pre-loaded coverage maps and signal fading prediction allow for smooth transitions between spot beams and bands to achieve optimum availability. The antenna controller and embedded router take care of switching user traffic between bands, beams and satellites.


IEC60945 compliance for EMI, Climatic and Vibration requirements means that the antenna is qualified for professional maritime equipment applications like Oil & Gas operation vessels.
The antenna can be managed and updated locally or remotely by the same software run by Skytech for all other antenna series, making it fully supported by the Skytech Service Centre throughout its life, within single or fleet diagnostics with an intuitive web-based server, gathering real-time and historical performance information from all ships.
