Swan made a little matchbox for Mobile use to match low impedance Mobile whips. Anyone got one in their Junque Boxe ? I have an ancient Multi-Elmac A-54H that was designed for Mobile use and would rather not modify the Tank Circuit for 50 ohms. BTW, the final is an 807 with a 3-39 Date Code. And it still works !! 73, Dick, W1KSZ
