The possums could be used to your advantage if you are having interferrence
problems as at your field day site. They would form a stub of sorts,
relatively broad banded because of their somewhat lower conductivity factor
and also resulting in a low velocity factor and actually causing the possum
to appear to be much longer than it really is and the frequency of resonance
to be lower also. If they were tuned to the interferring frequency, you
might just be back in business.
Have you performed any testing using the possum stub?
