Hummmm! some one rather than me saw the same performance of
the bazooka. Years ago I removed a dipole and used RG 58 to
make one. It lasted about 2 rainstorms before it wasn't
tunable.
Rick, read the theory on this type of antenna before you use
a bunch of coax that will then only be good for jumpers.
Insulated wire will be lower noise than bare and bandwidth
is only about 3% of frequency on any good antenna. The
Dallas area is prone to ice so the weight will be monstrous
not counting the wind load.
The joy of being a ham with many frequencies to tune. You
will never have an antenna that is right on frequency all
the time.

Use one on 160 and one on 75 years ago. Claims of less
noise and greatly
improved bandwidth were bogus over the same type of single
wire
configuration. On the plus side, great wind catcher so you
need strong
supports especially if used in a dipole configuration.
Also, if your area
is prone to ice storms, larger surface area of antenna is
a great
collector. You'll need strong rope. Bandwidth improvement
was minuscule
over a dipole. It think Wallt Maxwell had some articles
about this
antenna years ago, "fact and fiction". Lots of info on the
web. If you
get water inside the coax and it then migrates, it will
drive your SWR
readings all over the place. After several ice storms, I
finally gathered
the antennas up and threw them in the trash can. Wire
works just as well.
