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,
