Your Theoretical System Operating Margin is:

Operating System Margin:
Calculate Free Space Loss: FSL = (20 x Log₁₀(FreqMhz)) + (20 x Log₁₀(DistMi)) + 36.6)

Receive Signal: RXS = TXPower - TXCableLoss + TXAntGain - FSL + RXAntGain - RXCableLoss

Operation Margin: SOM=TXPower - TXCableLoss + TXAntgain - FSL + RXAntGain - RXCableLoss - RXSenss
