I've had to place devices in plastic foam boxes to find the source of the
"anomalous" thrust, which turned out to be due to aerodynamics of airflow
around the object which was heated by current flow. Plastic bags have
aerodynamics of their own, as well as static electric effects, and bouyancy
effects. Anything using DC is also hard to verify unless a 360 arc can be
repeated.

Fig. 3 - Closed ended coaxial drive with bulged power housing
As noted in Fig. 3 of the earlier post the end of the thruster can be
capped off provided the central conductor terminates well before the end
of the outer sheath. There would be no significant reduction in thrust due
to radio wave emission. A capped device should not have any significant
emissions. It could even be evacuated in order to achieve good insulation
and avoid arcovers.

For sure.
