If you want a really broad-banded Bazooka, use RG-174. :-)

Egad, Cecil! It's evident I wasn't too bright years ago when I showed why the
bazooka gets its meager increase in BW from resistive loss, not reactance
cancellation. My scamming genes hadn't developed to the point where I even
thought of marketing it instead of panning it. As you said, Cecil, with the
higher loss available using RG-174 vs RG-17, think of how rich we could have
become if we'd let the morons continue to believe what a great antenna it is,
and sold em with 174.

There's a Double Bazooka currently on eBay for the "Buy it Now" price
of only $60.

Part of the sales pitch is:

"The Double Bazooka antenna was designed and developed by the M.I.T
staff in the 1940's as a radar recieving antenna. Its design was
modified for the hf amateur radio bands."

There's one born every minute...

There is nothing inaccurate in that description as far as I know.

Let's be fair about the Double Bazooka: It does exhibit a broader SWR
bandwidth than a dipole antenna.

I've now used the 160m coaxial inverted "L" described by Ted Cohen N4XX
in the January, 2000 issue of CQ Magazine. It has been up for about
four years, during which time I've worked just about any exotic DX which
has appeared on the bands--even FT5XO.

The antenna is simply half a double bazooka and it runs vertically 65
feet and horizontally a little over 62'. The entire 200 KHz of the 160m
band is covered with SWR under 2:1. Of course the fact that I have
about 6,000 of radials under the thing may help more than a bit. Can I
assume that since the antenna is only half a double bazooka that the
loss of power in using it would be roughly half of that using a double
bazooka dipole?

I can often work EU stations with just 100w. I could seldom do that
from my Cincinnati QTH in the late seventies and early eighties using a
60' omega matched aluminum tower with TH6DXX as top loading.
