Getting ready to install a 1.2 M dish at my place in Wisconsin. Where should I look for pipe? Thinking of going with 2 1/2" (2.88" OD) x 7' or 8'. The pole will be used with a Stab 120HH. Need to get a pole in the ground before the 'big freeze'.
Depending on what kind of winds you get, you might consider schedule 80 for the extra strength and, perhaps more importantly, rigidity. The OD for is the same for all pipe schedules.
Hurricane alley here. One thing you can do is fill the pole with cement once it’s in the ground. I was having a lot of problems with my motorized KU dish so when I put a new pole for it I put it twice as deep as before, twice as big around the hole, three times as much cement (4x 80lb bags) and I put a length of fence top rail down the middle of the pole then packed both of them solid with more cement. There is NO WAY that pole will ever bend and it will take a flippin crane to pull it out of the ground. That’s what I’m going to doing to all the new poles at my new house I’m moving to.
It's a nice feeling doing it RIGHT the first time, isn't it? Sure saves a lot of time and heartache later...
Cement is CHEAP, it's easy to dig the hole a little deeper, and a little larger the first time, and you'll never have to worry later that your extra $10~ worth of cement was wasted for getting some extra bags of it.
if you fill a pole with concrete, make sure you mix it good before putting it in the pole.Hurricane alley here. One thing you can do is fill the pole with cement once it’s in the ground.

I also put a bag of gravel at the bottom of the BELL shaped hole, and put a leveled concrete patio paver on the middle top of the gravel.
The gravel helps with drainage for ground water, and the paver keeps the pole from sinking (pole sits on top of the paver) before the cement sets up and gets hard. Then again, our soil up here is sandy-loam (I can dig a 4ft deep hole in 10 minutes with a post hole digger) which makes it quite easy for the pole to sink if not properly supported before the cement gets hard.

years ago i did a service call on a direcway satellite internet system where the original installer filled the pole with dry concrete and just poured water in with it.
