FL Native said:the guy that blew up his amp had nothing to do with coax length. they say use around 18 feet cause that is a 1/2 wave multiple on 11 meters. the coax lenght will only make you see incorect swr readings if your antenna is not tuned and your not using a 1/2 wave multiple of coax.
now 18 feet is only getting close or around a 1/2 wave multiple. actualy it depends on coax type. meaning it depends on the veolicty factor of the coax to determine what a 1/2 of coax is on any given frequency.
heres a link to explain the coax thoery to maybe help displell some of the myths on coax length.
