Hi Denny,

Sounds like what Wall Street calls "taking a poison pill."

Run the coax underneath the
vehicle and wind it around the perimeter leaving it a shorter than an
electrical quarter wave... Leave it insulated from the vehicle... Seal
the ends against water and salt intrusion... Use a coil at the feed
point to establish resonance on this counterpoise...

Another poison pill.

Compare the field
strength to the conventional method...

If it can deflect the needle. You might have to duct tape the FSM to
this novel radiator to do that.

Care to guess what the circulating currents are going to be in your
insulated mast antenna?
