Hi Wayne,

There a reason for concern for eliminating the choke in the antenna
circuit.  I noticed that there is no DC path to ground to eliminate the
chance of static potenital build up on an antenna from discharging a high
voltage into the rig. This may be the reason why some builders have
experienced blown detection diodes in some ATU's etc.

I think that is a good practice to install a 47K 1/2W carbon resistor
across the antenna terminals to act as a bleeder resistor when there is a
capacitive coupled output.
