I have been contimplating putting in a mast for wires.  I was going to use 
2 irrigation pipes, have an attatchment at the top for a water hose, slight 
necking at the other end, prepare the soil by cutting back the sod and some 
soil, the water drilling the pipes into the ground.  I figured that a 10ft 
pipe in 6.5 with 3.5 up would hold a 50ft mast.  Having the 2 pipes would 
allow the mast to be tilted.  Other than pulleys for wires, a 10m vertical, 
and maybe a loop for 40m.

So your idea of augurering backs me up a bit, thank you.
