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.
