f-250ford,
Oh man, it's one'a them days. Had a really brilliant post going, stopped to do a search to make sure I was right about a couple of things, came back and it was gone. Rats!
To make it short and sweet, since I can't remember exactly what all that 'brilliance' was now, if you're looking at a new 'Atas' antenna, do yourself a favor and check out a few of the other similar antennas. There really is/are better choices.
Having the 'best' mobile antenna around isn't all it's cracked up to be. There are always compromises. The 'trick' is determining which of those 'compromises' you're willing to put up with.
I'm not the biggest screwdriver antenna fan in the world. I have one and I'm satisfied with it. It isn't the 'best' HF mobile antenna, but then, it's sure more convenient than the 'best' one (still got that 'best' one, it's just a Royal P.I.T.A. to use, and NO, it isn't for sale, well, maybe ($)($) ).
Good luck with whatever you decide.

Besides, who'd want something with "AES" in the middle of it? (Sorry, couldn't resist)
