Too many connections under tensile stress made worse by the wind (and
ice) cross section being mostly plastic with only a small copper cross
section for tensile strength. That's what kills the reliability of the
Bazooka.
More pieces always reduces reliability. The Bazooka is not inherently
balanced and can have the same feed line radiation effects as a plain
dipole. Whether those are good or bad depends on the situation.
