3.0M TVRO Antenna

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