Lester,
Not sure what parameter you are referring to when you note that the ha;lf
square has a narrow bandwidth of less than 2-1. The half square, when
used for its vertically polarized radiation, is a resonant antenna and has
an operating bandwidth adequate for covering any one of the hambands from
40 - 12 meters. It can be fed at an upper corner for direct coax
cnnection. It can also be fed at one of the lower ends via standard
voltage node methods, for example, a parallel tankcircuit with a coil tap
for the coax feed point. Some users prefer the lower end of one vertical
for the convenience of its position and the ease of feeding the antenna as
a gneeral purpose antenna on higher bands. Others who use the antenna as
a dedicated one-band antenna prefer the coax feed. The feed method makes
no difference to the vertically polarized pattern.
Hope this is useful.
