I agree with Dave, 
PVC is very brittle when it's cold out side. 
Also the White PVC will get brittle in the sun. 
The Grey PVS for Electrical work is the best for out doors.

Max-Gain Systems sells fiberglass tubing in various sizes and lengths.  If you want 'really strong', they carry solid rod as well.   From my experience with PVC, it's somewhat brittle at cold temperatures.  Disclaimer: no commercial interest.

I had some 1 1/2 inch underground electrical conduit laying around, grey plastic, pounded in to soil, no guy wires on 18 ft verticle, this simple one with loading coil on base.  Setup about 9 months ago, no issues

I have 2 ground mounted verticals, both happen to be Cushcraft which use a 1.25 inch fiberglass tube.  Sometimes a wind gust will bring down the vertical even though have staked guy ropes on each.  Or this time my shorter vertical came down so I am suspicious a deer may have ran into my guy rope.  Of course this cracks the fiberglass usually at the bottom connection to the grounded base.  Last time I ordered these from the manufacturer it took a couple months.  Does anyone use an alternate recipe or buy fiberglass tubing from somewhere?  I did see someone using 2 PVC pipes nested into each other for strength - of course I prefer a solution with more common materials.  Curious what others are doing.
