Glad to save you the needless work....but, just remember... "if it don't
shine...it'll still work fine...only it won't look pretty. =20
Also, when you clean the joints... seriously...., don't forget to clean the
inside of the outer tubing... although, I rather suspect that most of the
electrical connection is being made with the stainless sheet metal screw
only- but I could be wrong on that one. I'll have to check my antenna
modeling programs ;-)
P.S. Other unattributable quote of the day....." South America has cold
summers and hot winters, but somehow they still manage."
