9 Metre Ku Band Earth Station Antenna

9 Metre Ku Band Earth Station Antenna
Product Details

Newstar 9m earth station communication antenna can operates in standard c/ku band and extended C band 3.4~4.2GHz and extended ku band 1.7~12.75GHz. 

As a manufacturer and supplier with more than 10 years expereince in the satcom feild, newstar grow gradually under the customers' continuous guidance and help. 

9 metre earth station antenna details:

(1) Antenna type: Cassegrain

(2) Polarization: C-band:Dual circular / linear

(3) Motorized polarization is available

(4)The steel part adopts hot spraying zinc treatment, then bottom paint and final surface white paint; the aluminum panel  adopts anodic oxidation treatment, and then coat with bottom paint and final surface white paint.

(5) Designed lifetime:15 years.
