[Boatanchors] ant info

[Horace W. Hall]

The 'Windom' is a multiband ant with the same electrical length on all
bands. The off-center feedpoint causes it to be matched to its feed line
(or nearly so) on even multiples of the lowest freq it is cut for (as
opposed to center-fed wire antennas that like odd multiples).

It radiates a pattern much like a dipole on the lowest freq (F1) its cut
for, and like full wave on the freq 2xF1, etc. So if you cut one for 80
meters, and feed it with a 10 meter signal, it will have lobes all over t=
he
place rather like a longwire. =


If you use the original Windom single wire feed, there is significant
radiation from that vertical feed wire, too, so you get some RF going off=

in nearly all directions. The various modifications to the original Windo=
m
feed use either coax up to a balun at the antenna or 300 ohm twin-lead to=

eliminate the feedline radiation.

When using the modified feeds, it also appears possible to attach more th=
an
one Windom to the same feed line rather like parallel dipoles. The articl=
e
that I saw this in actually ran their 2 antennas perpendicular to each
other instead of parallel. This was done to get one wire for 80, 40, 20, =
10
meters and the added one was cut for 15 meters.

eed an antenna that will have the major lobes so I can work in a noth
westerly direction.  I have a trap dipole that runs near east and west so=

get out very =

good to europe and russia, but not well  to anything west of iowa.
 =

Need to know what the major lobes are on a carolina windom ant as I can g=
et
one up =


running north and south, but have been told the major lobes of this anten=
na
are off the ends.

So wondering if the info I  have is dorrect and if so I guess it would ha=
ve
to run nw and se.
