After reading several articles both on and off the WEB regarding a
center fed antenna, only one article mentioned a recommended length for
the feed line.

some antennas, like the g5rv rely on a particular length of feedline because
it becomes part of the antenna and radiates on certain bands. others use it
as an impedance transformer.

It is also a myth that the feedline for the g5rv requires a particular length
because it becomes part of the antenna and radiates on certain bands. At the
antenna terminals the feedline becomes a transmission line with opposite
directions of current on each conductor. Thus the fields developed around each
conductor cancel resulting in no radiation from the feedline if it's dressed at
90° from the antenna.

In addition, it's also a myth that the feedline of a shortened antenna radiates.
Some believe that the portion of the feedline that makes up for the missing
length of the shortened antenna radiates--tain't so.
