New subscriber and relatively new to ham radio here! I am
seeking your input on just how the lobes of the antenna are affected by
the relative heights of the "arms" of the antenna.
I am blessed
with more than 4 acres of property. My antenna points to
the NE and the SW. The feed point is up close to 40' or so on a fiberglass
given the height of the eucalyptus trees on the property, the relative angles
of each half of the dipole are
different. The property is on a slope and the highest spot on the
property is the SW corner.
The end in the SW corner is at about
"10:00 o'clock" and 35 foot from the ground; the other end in the NE is
about "3 o'clock" and about 40' from the ground. I cannot raise the NE
corner [or the feed point] because I've run out of tree at 40'!
However, the SW corner can go up another 8' or so [to 43'].
The property itself resembles a very large soup bowl; high on the ends and
low in the center. The antenna is hung from the lower left and upper
right edges of the bowl [or in the 8 o'clock and 2 o'clock
positions]. Nothing fancy here; just the G5RV and an IC 775DSP running
barefoot. The antenna will work all bands from 160-10 meters accept 15...it
don't like 21 MHz much at all!
Which would be the best position for
1) as parallel to the ground as possible
2) raise the SW corner 8' more and see what happens
3) lower the SW corner to simulate the NE corner
4) expect a negligible change regardless of
what you do
5) leave well enough alone
Many thanks for taking
the time to respond!
