Formula and estimation limits

EIRP = Tx power − Tx cable loss − connector loss + antenna gain. Rx level adds receiver gain and subtracts FSPL and all losses.

Status uses theoretical link margin. Interference, noise floor, polarization, alignment, weather, EIRP regulations, and field conditions still require verification.
