Global Konet Alpha2 ESA GU420-PAA-47-K Antenna

Global Konet Alpha2 ESA Antenna

KONET 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 12 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.

Full-Duplex ESA Antenna Simultaneous Transmission and Reception

Alpha2 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.

Excellent Alpha OTM antenna performance with fast beam switching speed

Pol Switching Time: < 0.5ms
Satellite Switching Time: ≤ 0.3ms

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.

Electronic beam steering is much faster than mechanical motors. This is a significant advantage in multi-satellite tracking, etc. The fast response speed minimizes communication delays and maximizes efficiency.

Electronic control allows for very precise beam steering. This allows for precise control of the directionality and strength of the signal, minimizing interference and improving communication quality.
