The vex is the yellow box with the short antenna I had wrapped around the frame.
So next I soldered on about 3 foot of 22 gauge wire onto the Vex antenna. Then I put that antenna into a clear tube and zip tied it around in the circle as high up as possible in the droid. Doing a before and after test I gained about 5-12 extra feet of distance. But to safely operate him I still need to be around 15-20 feet away from the droid. Oh well I gained 5 something feet. I'll take it until I can replace this Vex system later on.
