One other idea came to mind which I acted on and that was to buy on
e-bay an inexpensive LNB complete with round plastic cap delivered for
around $6. I should be getting the dish and feed from directive systems
and maybe, just maybe I will get lucky and the plastic cap off the LNB
will be a close match to the OD of the DS feed.

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.
