FAQ
Q: What is an ANTI-5G WR75 LNB?
A: The transmit way by Matrix waveguide, LNB itself has anti-5G IMT @3.5G Band interference capability.
Q: What is a Strong Rejection-5G WR75 LNB?
A: WR75 LNB directly input 5G IMT@3.5GHz frequency from transmitting waveguide, Guard band=100MHz, 5G Power Level: -30dBm, WR75 LNB output Gain(in-band) no intermodulation, Output Gain no saturation. WR75 LNB itself has strong anti-5G IMT@3.5GHz frequency capability, because with un-linking the mechanical filter outside, WR75 LNB built-in high performance out-band rejection passive filter.
Q: What is High Gain Low Noise?
A: WR75 LNB High Gain: 63dB (Typ.), which can receive week intensity signal; Low Noise: 0.8dB(Max.), which can guarantee system better C/N value.
