5G interference C band LNB、LNA
■ extremely low noise temperature ■ 1:1 or 1:2 redundant function
■ 5G interference ■ out-of-band suppression function
■ low power consumption, high cost performance ■ overload and limit protection
■ easily installation and maintenance ■ LNA/LNB power supply monitoring
