What's the tallest pole anyone has used?
If over 15', what was the aprox. diameter of the pole?
Was it considered a standard installation- i.e. no additional charge?

Tallest totem pole: 173 feet (http://en.wikipedia....wiki/Totem_pole)
Tallest barber pole: 72 feet (http://maisonbisson....log/post/11155/)
Tallest flagpole: 410 feet, maybe (http://www.crwflags....gs/xf-supe.html)

Now then, how tall a pole do you need, and why? Antenna towers aren't rocket science, but they're not free either.
Yes, FTABlog is active again. Why do you ask?

I don't think any pole mount (including tripod) qualifies as a "without extra cost" installation.

Where's my pipe bending moment table???

What is the worst case wind situation at this location (I'm thinking pretty severe for North Carolina)? Obviously, the taller the pole, the more rigid (or supported) it must be to prevent even casual bending (elevation) or twisting (azimuth). Given that the target is 22K miles away, there isn't much wiggle room.

Not true. I got a pole mount for a must carry dish (61.5) at no charge straight from Dish.

I had a 61.5 dish on a 20 ft TV mast at about the 15 ft level and never had any issues with it. However, you need to use guy wires on standard masts every 10 ft or you risk lots of wind movement. Towers are a different animal, but also more expensive.

Cheers,

Doug

I have two Ku dishes at work pole mounted on the same pole. The lowest one is about six feet off of the ground and the highest is around 12ft. These are decent size dishes, bigger than a Superdish. The pole was welded and installed by a local sat installer who started in C Band and now does primarily Dish and DirecTV.

If you want to make something work hard enough you will work hard enough to make it work. In this case, you'll need a really strong pipe.

You can probably get some statistics on the strength of selected pieces of pipe. They really don't expect you to leave one end floating above the other on the stats sheets but it will give you some idea.
