So yesterday I was able to salvage the original pole that my 10 ft. mesh dish was mounted on, I cut it off at ground level and ended up with a 6'9 piece left over. With what I have read so far on pole mounting, I should have 2-3 feet in the ground with 4-5 feet above ground, correct? Just wanting to make sure that I have enough pole here to accomplish that, I would end up with 4 feet about ground for a 10 ft. dish....acceptable?
