Assuming the transmitter does not fold back, the 11% reflected power will not change the signal strength... The reflected 11% will be 88% radiated on the return trip (minus any line losses) and 88% of that on the next round trip, etc... So, in the end the decrease in transmitted power is only a fraction of 1% for feedlines with low losses to start with ... Now, if we take transmitter foldback into consideration, ... ____________ If, as reported, more than 99% of the output power of a transmitter ultimately is absorbed/radiated even by a mismatched antenna system, then why would a transmitter need power foldback for such loads?
