* NOTE: According to the transmission line theory, the formulas used by the corresponding columns, - For the Voltage Reflections Coefficient (Rho) :(from SWR to Rho); [Rho=(SWR-1)/(SWR+1)] - For the Reflected Power Ratio (Prefl/Pfwd) in %; [100 x Rho^2] - For the Return Loss in dB; [10log Rho^2] - For the Transmitted Power in %; [100 - Reflected Power(%)] - For the Transmission Loss in dB; [10log(100/Transmitted Power(%))] * * Have fun and small SWR! 73 de Peter, LZ1LEN Back to my projects page |
