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.

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!
