more than half a century working with professional and amateur
radio antenna systems... All
I can say this is a never ending subject!!
The 44 feet long dipole, 22 feet on each leg came out of
the work of the prematurely deceased Len Cebik
W4RNL... (Figure 1 shows the 44- Feet Dipole
was an antenna modelling fanatic and guru at the same time who
had the wisdom to share his gifted knowledge with everyone who
approached him, like yours truly.
When I asked Len about him choosing the 44 and 88 feet
dipoles, he answered with both e'mail and printed correspondence.
By spending endless hours with sophisticated
antenna modelling programs that are a real challenge to learn
how to use because of the steep learning curve, Len found out
that for the frequency range of the amateur bands between 7 and
29 megaHertz, the
44 feet dipole, fed with open wire transmission line of
between 300 and 400 ohms
impedance was an excellent compromise, using, of course,
