Why not one rod and just switch the antenna wire between the resistor and
transformer primary? The relay would be a SPDT at the antenna side.
Whichever end is floating shouldnt have any effect. Place the second rod
20-30' away and ground the feedline shield there and also decouple with
ferrite at the antenna side of the rod.
