Gary appreciate the suggestion. I have not decided on a material yet. I
have been acquiring a number of different plastics, all uV stable that I
plan to test in the downstairs dungeon RF lab. I will be looking for the
IL and to see if the RL of the feed changes with the covering in place.
Refraction thru the plastic is another concern but I do not have an easy
way to test those effects downstairs.
