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.
