... In article fXh4e.129$Jt.53@okepread04, says... My friend says that a double bazooka is 98% efficiant and that a dipole is only about 70% efficiant. Is he right? Will a double bazooka outperform a dipole enough to notice a difference on 40m? I suspect your friend got his figures reversed. Any properly-constructed half-wave dipole is well over 90% efficient. The double bazooka gets its meager bandwidth improvement by adding loss. 73, Bob -- +----------------------------------------------+ | Bob Schreibmaier K3PH | E-mail: | | Kresgeville, PA 18333 | http://www.dxis.org | +----------------------------------------------+ Thanks Bob, Roy, Walter, Richard & Cecil! Wow - all the guru's agree for once? That fact alone leaves me to forget the idea of replacing my ladder line/coax fed 40m dipole with a Bazooka. Info - my current antenna started out as a Van Gordon "All Bander", a 134' dipole fed with 100' of ladder line. I trimmed 50' off the ladder line and have a 12' rg58 coax feeding a CD size 13 turn coax coil which feeds the ladder line going up to the antenna (which I trimmed to 7.185 mhz). It's a flat dipole (almost) up 25'. Due to a lack of space, I would have had to take that antenna down to put up the Bazooka so comparing the two would have been almost impossible. Thanks again, guys - you rock! -- 73's es gd dx de Ken KGØWX Grid EM17ip, Flying Pigs #1055, Digital On Six #350, List Owner, Yahoo! E-groups: VX-2R & FT-857 |
