3.0M TVRO Antenna

3.0m  SMC antenna reflector adopts compression molding with the characteristics of high precision, good consistency, and non-deformation. And it also has the features of low density and it is hyperbaric, which is stronger than steel and lighter than aluminum. And its compressive capability is 12 times higher than aluminum. Reflector with more pieces combination has the features of good exchanging capacity, anti-corrosion resistance, anti aging and long lifetime up to 15 to 20 years. Specially designed feed is matched perfectly with reflector, which makes transmit-receive reach maximum efficiency. Motorized polar tracking structure can satisfy full orbit satellite cover. And the assembly and adjustment is simple and practicable. The reflector adopts orange peel design which can have the function of waterproof and reduce damage to high-frequency tuner.
