If I remember correctly as it was explained to me some years ago, The
transmitters are mearly broadband amplifiers transmitting just what thay
receive in a given bandpass. The antena is a longwire matched to the
amplifier. I hope I am right about this it has been a number of years since
I was told this by one of the persons who built the system for our Vista
Ridge tunnel in Portland OR.
