AI explainability

Link is locked with 15.0 dB C/N margin. Dominant residual loss: rain fade.

Rain fade0.12 dB · 99%

Rain rate 2 mm/hr at 14.1 GHz → specific-attenuation model γR·L. Ku fade is mild in tropical rate.

Pointing loss0.00 dB · 0%

Beam offset 0.00° vs HPBW 1.24° → 12·(θ/θ₃dB)². Wind 20 km/h drives the residual drift.

Reflector gain0.00 dB · 0%

1.2 m dish gives ~45.0 dBi at 14.1 GHz. Larger dish → narrower beam → higher gain but tighter pointing tolerance.
