The antenna will be capable of use on ALL frequency so I will be able
to observe the ups and downs of the reflectors applicability when I
get it up.
7 inches of snow with two more clippers on the way has put a crimp in
my immediate plans
My thinking is that as the antenna is end fed the need for extra large
size reflecter goes out the windown
as the reflector may perform as a flux guide similar to a long
solenoid. This is new ground so I do not
want to nickel and dime it to death until I have more experience under
my belt. Present dish
education is heavily weighted to phase methods used in planar designs
or alternatively solely on VHF,
the later being slanted designs via pitch and other factors that do
not apply in my case. since my
design evolves around equilibrium . I would also point out that some
of Kraus's work is being thrashed
with respect to gain and may well extend to use of deductions instead
of observables which was heavily used
in empirical gains with respect to pitch angles. Bottom line at the
moment is that the antenna for top band
be light and small enough for me to handle on the towerand on the
ground without the need for me use my prop pitch rotor,
which by itself is a handfull or to call for additional help. If I
can't handle it alone then it defeats my original object with respect
to
small antennas without the normal compromises with respect to
electrical wavelength.
That ofcourse does not rule out diode action in the short run with
respect to poultry fence mesh as a reflector.
