True, HOWEVER if your eyes are at the level of the top of a CB
antenna, you won't see much more than 40 miles over water when the
skip is out. Try going to the top of a mountain some time and THEN
see how far your CB can communicate! (Don't forget to take the same
antenna you used in your previous experiments.)

KF4ICR, huh? OK, I'll tell you a little bit about "Mr. B" who lives
at 3346, (I won't say the name of the Drive). He has a codeless Tech
license which was issued for the first time, (not a renewal), on
March 27th of last year, and it will expire Mar. 27, 2006. Also, he
gets his E-mail via Juno, but I won't say what name he uses there to
protect his privacy and avoid your temper.
BTW, it took me less than 5 minutes to get that information and more
about him!
JS> forget.) ...And I too have talked around the world on 4 watts (11
JS> meter band, using a super-laser 500 beam antenna on a 80 foot tower).
Ya, but I doubt that you did it within the last 2 years! (Sunspots,
ya' know). On the other paw, I heard, (and could have worked - if
there weren't at least 100 other American Hams wanting to do the same
thing - this afternoon... IN SOUTHERN AFRICA! Of course, this was NOT
on C.B.! The cute part is that I was NOT using a fancy antenna - just
a piece of wire about 20 Ft. long!
