Feature
All the offset satellite dish antenna we designed owns the standard features as,
* SMC reflector surface using molding, high precision, consistency, and no deformation;
* Low density, high specific gravity, strong as steel, light as aluminum;
* Compression performance is 12 times that of aluminum;
* Reflector surface multi- chip combination, good interchangeability;
* Anti- corrosion, anti-aging, long life 15-20 years;
* Specially designed reflector is perfect match the feed. So that the transceiver is capable to achieve maximum;
* Simple installation, adjustment.
* Reflector surface orange peel designed, providing rain attenuation and reducing the tuner damage.
