Using a pole to get over trees?
Posted 28 July 2006 - 01:14 PM
The pole needs to be just a bit less than the height of the trees.
You do however need a good 90' runway to get up enough speed to vault properly. Also I'd recommend a good airbag on the other side of the trees.

Look through the sight glass and "back up" till the elevation angle numbers "misses" the trees. .
No math. no headACHE.

Do it the old fashioned way: Get a toilet paper tube or paper towl tube. Go take a walk to your backyard where you want to put your pole. Face the correct direction to the south for your location. Look through the tube at the angle you need (35 degrees in my case). You see clear sky in the tube? Now squat down to the point where the tube will be where your dish will be. Still see clear sky? Then you're all set and will get a signal.
I like that old school solution. I do remeber about four years ago after 3 DirecTV installers said it was impossible I had about a ten foot pole at the spot where I want to plant the new slimline. I used it to adjust the dish to get the signal then moved it to the house but had to add eight more feet to the pole. Over the years I've had to slide a five inch brick under the pole to keep it over the tree line. So using my old school math skills I would think that a 12 - 15 foot pole should do the trick. Thanks to all for information, input and twisting my mind on math problems.
