Satellite signal blockage can occur due to heavy rain (attenuation >10 dB at 30 GHz), physical obstructions (buildings/trees blocking 5-20° elevation angles), solar interference (occurring near equinoxes for ~10 minutes daily), incorrect dish alignment (even 1° error causes 30% signal loss), or interference from terrestrial sources (e.g., 5G networks at 3.7-4.2 GHz). Regular alignment checks […]

Waveguide arcing involves six key aspects: breakdown voltage (typically 10-30 kV/mm), surface roughness (Ra <0.4 μm recommended), gas pressure (maintain <10^-3 Torr), material purity (99.95% aluminum preferred), RF power density (keep below 5 kW/cm²), and proper conditioning (gradual power increase over 2-4 hours). Proper waveguide cleaning with alcohol and strict particulate control (<100 particles/ft³) are

Optimize the five core indicators of satellite signals: 1. Signal-to-noise ratio ≥ 12dB (military waveguide insertion loss < 0.15dB/m); 2. Bit error rate < 1E-9 (polarization coding + LDPC error correction); 3. Level calibration error ± 0.3dB (Keysight N9048B spectrum analyzer + λ/500 flatness); 4. Rain attenuation margin 7dB (Ku-band dynamic power compensation); 5. Polarization
