I need to fine tune how the PCBs mount in the PVC pipe end but it's getting there.  I redesigned the antenna boards to coplanar wave-guide and am getting better results.  I put a dummy load on my antenna switcher and discovered that was causing VSWR problems.   Now waiting for the redesigned board.  The rubber ducky antennas are way too flexible and I'm sure better ones are out there.  I found flag pole mounts that I plan to attach the bottom PVC legs to magnets on the car rooftop.
