There are a lot of folks who will tell you that blowback engine oil will be an
insulator and not affect the transponder antenna. I have no argument with their
theory that oil is an insulator and cannot affect antenna performance at 1.06
GHz.

However, as they say, boychick, engine oil on the transponder screws up
performance. Like it or not, theory or not, it happens. It matters not whether
or not you believe it, it happens.

-My question is this: Does it seem reasonable that a very small amount of
-oil on the antenna can effect transmission that much?
