Hi guys,
There are SO many variables and SO many opinions they should all be condensed into a pat answer and the thread made sticky. (sigh) Sorry 'bout the sarcasm but frankly I'm SO tired of answering antenna questions, hundreds, no, thousands, no, MILLIONS of them! AAARRRGGGHHH! (;->)
Now to get just a BIT serious, MY pat answer is whatever works for YOU. Smokey says "Only YOU can prevent forest fires." and I say first do your homework, (check out the specs and eliminate the snake oil) then experiment until you find what suits your requirements at your particular location.
