Δορυφορική κεραία Kathrein KEA 650/G

The Kathrein KEA 650/G satellite antenna is a high-gain reflector designed for reliable reception in the 10.7–12.75 GHz satellite band. With a gain of 36 dBi and an elevation angle capability from 0° to 80°, the KEA 650/G suits diverse installation scenarios, including low- and high-elevation satellites. The antenna's graphite finish and compact 4.5 kg mass combine practical handling with weather-resistant construction for fixed satellite reception systems.

Advantages

The antenna provides a stable, high-gain signal across the full Ku-band receive range (10.7–12.75 GHz), enabling consistent reception of weak or distant transponders. The broad elevation angle range simplifies alignment and makes the unit adaptable to many geographic locations and mounting positions. Lightweight construction at 4.5 kg and a corrosion-resistant graphite exterior reduce structural load and maintenance requirements for rooftop or pole installations.

How to use

Mount the Kat hre in KEA 650/G on a suitably rated pole or bracket ensuring the structure can support the 4.5 kg antenna and local wind loads. Align the reflector toward the target satellite using azimuth, elevation and skew adjustments; the broad 0°–80° elevation range allows aiming from near-horizon to near-zenith satellites. Connect the feed and coaxial cable to the receiver system using appropriate weatherproofing at the connector. Perform a signal-level sweep and fine-tune the antenna orientation for optimal carrier-to-noise ratio and minimum bit error rate.

Recommendations

For stable long-term performance, use corrosion-resistant mounting hardware and seal cable entry points against moisture. When installing in exposed locations, verify local regulations for wind and lightning protection and consider professional alignment services for multi-LNB or multi-operator configurations.
