Collinear antenna.
A collinear antenna may be used in the same way as a 3 element Yagi to compensate for the losses
in long lengths of coaxial cable. This type of antenna is generally used at a central site with more
than one remote site or at a repeater site. The collinear antenna looks similar to the dipole, except
that it is longer.
