<DIV><FONT face=Arial size=2>Dave,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Give thought to what happened. I know 42 inches
probably probably means a lot to you and I can understand that. You have
determined the weak point in the system. If your mast was steel, continued
flexing softens the metal at the flex point. Aluminum becomes brittle with
flexing (work hardens). If you leave it where it is, you may not have to worry
about wind. Model the antennae to see what the decreased gain is. Maybe you
don't want to go back to the full 42 inch difference. There is a gain to be
achieved in never having to worry about wind and ice load and wind. My
antennae are not as high as they could be, but ice and windload or wind have
never been a worry. My three element 6 M beam is set up with a very crude
slipping clutch so that all the mast and rotor rotate if the wind really gets
a hold of it. This way a component of the energy that might bend the mast or
damage the antenna gets translated to a rotational component. I have to rezero
rotor every so often, but that is trivial. Over the years, I have heard some
strange creaking and groaning, but have not lost an antenna or had damage
since I have been licensed. On the flip side, my stuff is not as effective as
if I pushed the envelope. But physics and gravity will always
win!</FONT></DIV>

<DIV><BR></DIV>The mast on the HF tower bent just above the thrust bearing
in last night's wind. I dropped it down and cut the mast just above the
bend. The HF beam and loops are now 42 inches lower until I can replace
it.<BR><BR>The bend was very slight but was more than enough to bring the
top about 30 degrees off vertical.<BR><BR>No other damage here.<BR>
