Default Wind Turbine Attached Galvanized Steel Pole

Hello Folks,

Recently I acquired a small 12v 500watts wind turbine with all the goods (charge controller, dump load, etc), but the pole for the the installation as is normally the case. The wind turbine came straigh from Germany to my door, the following:



I never built a pole before, and this will be a large one (over 14 ft). Since they do not sell pre-fabricated poles for wind turbine for the general public, I am planiing on making one out of 2 1/2 galvanized steel pipes (normally used for fences) by coupling smaller ones together. It seems that digging a 1 meter hole (below freezing line) and use regular pre-mixed concrete (two bags) would suffice (or would be a need to anchor it to the ground with a different support system). The upper portion of wind turbine pole will also be attached and thus supported to a building/structure (back of the garage) as shown on the sketch below:



I realize that the wind turbine represents a mechanical load on its support system, so was wondering how to best approach this case. Also, any hints about where to buy the support strap for the upper portion of theh pole?

thks

I think that might be over kill, I think you could just look at antina masts and the hardwear for those.

I'd rather overkill than have a 40 lb missle launched during a wind storm...

How much does the wire weight hanging from a weather head?

A service cable doesn't have a propeller strapped to it.

Yep, I am familiar with this video (saw it a long time ago). He seems knowledgeable, but ultimately he is trying to sell his product: AC output wind turbines. This is an excerpt of my post on youtube back then:

"P = V * I is valid for both AC and DC. The mainstay herein is that DC usually uses low voltage which then is compensated by higher current output (I = dQ/dt), thus requiring more robust (and expensive) wiring. So being AC or DC has no bearing with the size of the wiring, besides there is no inheriting property of the DC that would hamper current flow or otherwise require wires with larger cross sectional area. By simply increasing the voltage in the DC source (arrange the solar panels in series) one would eliminate the need for expensive wires and increase the max length of the wires"

I will leave that discussion for people who understand what you are talking about I was looking for the more basic information.
Like your question about the mast.
Or what happens to the cable if the wind always turns the tail clockwise.
He talks about start up speed but he dosn't talk about when it would stop, would that be the same? If not I would want a starter.
I think from what I understand about propellers his talk about the blades is right on.
The more I think about, the questions come up
