[OKDXA] VU7

[Bert Aaron]

Gene,

The short path heading is 14 degrees and long path is 194 degrees. My
antenna peaks at 8 degrees vertical arrival angle and is 8 dB down at 2-3
degrees. For your situation assuming a 3 element Yagi at 55 feet and using
the HFTA program on flat terrain, your arrival (vertical) angle peak is
about 18 degrees and at 3 degrees you are 11 db down from the peak. Hope
this helps.

73,

Bert K2BA

My tower is a 55 footer.  I think setting it on short path is what I'd 
better do and I'm also going to make it a point to rotate it a couple of 
times just before I go to bed and see if that'll help keep it from freezing 
up during the night.  Do you recall the heading you were using for short 
path Bert?
