Konet Alpha2 Antenna

Ku-band OTM electron beam steering ESA antenna, marine, aircraft, vehicle mobile service



Ultra-Compact and Lightweight Design 


Its extremely small and light form factor imposes virtually no limitations on installation space. The antenna can be easily installed on vehicles and vessels, and on the ground, a elevation adjustment kit ensures optimal performance. 

Full-duplex Electronically Steered Array (ESA) Antenna 

It simultaneously handles transmission and reception (Full-Duplex) and automatically tracks GEO satellites at ultra-high speeds without mechanical driving parts. his design maintains a stable, two-way link even in highly turbulent environments.



High Performance & Reliability 

Despite its compact size and 25.2 kg weight, the unit is engineered to MIL-grade durability, ensuring stable operation even in harsh environments up to 60 °C. The IP66 protection rating provides strong resistance against dust and water, delivering high reliability for demanding field applications.


Built-in Modem and One-Box Solution  


With an integrated modem board and OpenAMIP-based modem interface, the system completes service setup automatically with no additional configuration after installation. Built-in Wi-Fi support enables seamless wireless connectivity for field operations.











Alpha2 ESA is an electronic beam steering antenna that has been proven for export worldwide, boasting stable performance and strong power output. 


Alpha2 ESA antenna features an EIRP of 49 dBW and a G/T of 11 dB/K, which is usable for geostationary satellites (GEO). It proves that OTM services are possible while on the move, and is used on SUV and ships.
