Operating System Margin

Enter details and press calculate:

Frequency (MHz):                
Distance between sites (miles): 
Transmit Power (dBm):           
Transmit Cable Loss (dB):       
Transmit Antenna Gain (dB):     
Receive Antenna Gain (dB):      
Receive Cable Loss (dB):        
Receive Sensitivity (dBm):      

Free Space Loss is:    
Received signal is:

 

Your Theoretical System Operating Margin is:

Please be aware that these figures are based on a clear Fresnel zone. If the Fresnel zone is encroached then the operating margin may be reduced by as much as 10dB.
