We just went through a big wind storm all last night [ thursday night/fri
morning]. The commercial AC power flickered and dimmed
a few times. It eventually died for 2 hrs.
Ok, what happens with the HDX-689... when it's fully extended, and els all
broadside to the wind.. and power goes off ??
Can these things be brought down manually .. safely.... by another method ??
[ hand winch, cordless drill, etc]
I'm seriously thinking of installing a wireless wind speed indicator on top
of the new tower.
I can just see myself in the basement, with headphones on, totally oblivious to
the wind outside. The usual deal is, when winds hit 35-50 mph,
trees come down across the power lines by the nearby park... and there goes
the power for 2-4 hrs. Meanwhile the storm has not hit it's peak ..yet.
Local wx forecasts are usually accurate.. when they predict lousy wx.
Plan B was either add UPS power.. or a gen set. I don't have a clue
what the start up current on the 1 hp motor is.. when retracting a HDX-689.
It has positive pull down featrure, but it's still gravity that's doing
most of the work. A UPS that could provide 120 vac @ 20A CCS for 4
might work. Starting a gen set at 3 AM... in the middle of winter... in the
middle of a wind storm is no fun either...esp if it doesn't start.
IF the local forecast is predicting 'high winds after midnight, 110 kmh'
then at least I have some advance notice... and either don't crank it up,
or only crank it up part way, etc.
What does everybody else do ?? This install will have a lot of weight on
top.. and 4 x ants, and 2" OD x 3/8" chromolly mast.
Later.... Jim VE7RF
