Global Konet Alpha ESA GU540-PAA-55-K Antenna

Global Konet Alpha ESA Antenna

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

Alpha ESA antenna features an EIRP of 55 dBW and a G/T of 15 dB/K, which is usable for geostationary satellites (GEO). It proves that OTM services are possible while on the move, and is used on SUVs and ships.

Full-Duplex ESA AntennaSimultaneous Transmission and Reception
Alpha ESA antenna uses full-duplex to simultaneously transmit and receive, maximizing data throughput. This eliminates delays between data transmission and reception, and increases bandwidth efficiency in two-way communications.

The simultaneous transmission and reception capability allows for more data to be processed faster. This is particularly advantageous for high-capacity data communications such as high-speed Internet, real-time streaming, and high-resolution video transmission.

Full-duplex ESA antennas are highly compatible with next-generation communications technologies such as 5G and 6G. These technologies require high-speed data transmission and low latency, making full-duplex mode essential.

Fast beam switching speed enables satellites to track and communicate reliably in real time with fast-moving low-Earth orbit satellite users or base stations. This is especially advantageous for communication with moving aircraft, ships, and vehicles.

Signal interference is a major problem in satellite communications. Fast beam switching speed allows signals from specific users to be quickly switched to another direction to minimize interference. This allows for cleaner and more stable communication signals.

Fast beam switching speed enables efficient allocation of network resources. Antennas can quickly switch beams as needed to optimize resources and improve the overall performance of the network.

Electronically steered beams without using traditional mechanical motors
Without mechanical motors, ESA antennas have no moving parts, avoiding mechanical problems such as wear, failure, and maintenance. This greatly improves the reliability and lifespan of the antenna.
