Good Afternoon,
Today was a good day to work on antennas. Steady rain, dense fog,
and light winds. When I first raised this antenna I had few choices for
where each leg could go. After the recent thinning my options are much
greater. So I moved the leg which was at 300 degrees to point at 10
degrees. The leg which is now at 140 degrees would be better at 190
degrees but that will take some work with a chainsaw. Chainsaws and
muddy footing don't mix so I will wait for a drier day. While there is
a tall cedar right where I want it there are three young hemlocks in the
way. If I take out the middle one all will be well.
I woke up yesterday with AZ on my mind. During breakfast I decoded that
cryptic thought. Someone had told me QTH AZ but I did not remember
putting that state in my report. After checking it and actually reading
my notes I found the problem.
K0JFJ - Nick - TX should read K0JFJ - Nick - AZ
Sorry Nick, though depending on where you live in Texas it can be like
living in Arizona. But then there are many places which are not
similar. There is no comparison between Flagstaff, AZ and Houston, TX;
each has its unique features.
Hopefully the new antenna placement will aim farther south than did the
previous arrangement. I put a T-square on a map of the US and used that
to determine where to place each leg. If I had a true dipole over 1/2
wavelength above the ground the main lobe would point at North
Carolina. But each leg's end is not as high as is the center. The
interior angle is around 150 degrees so the antenna is not quite an
inverted V but the propagation pattern should be wider than a true
dipole. I found when I dropped the ends of a shorter antenna stations
to my north and south were stronger. Next Sunday I get to test it on
both 20 and 40 meters.
Until then 73,
Kevin. KD5ONS
