An antenna exhibiting improved transmission and reception capabilities. The
antenna does not make use of a solid support tube or solid support rods
used by previous antennas to support a sub-reflector or other device above
a main reflector of the antenna. Instead, the antenna employs the use of a
low dielectric constant, perforated, support tube to support the
sub-reflector, patch antenna, or other form of antenna element above the
main reflector. The perforated support tube permits radio frequency
signals to pass through the tube, thus decreasing signal degradation
experienced due to reflection of the signal off the solid support tube or
off the solid support rods.
