The problems with pole mounts are that 1, people bump into them. With rider mowers or just in general, damaging them. 2nd, water fills the pole from the top when it rains and sits in the pole, which will rust it from the inside out. Third, poles have to be set for after the initial visit, which means a 2nd truck roll for minimal units per job instead of what could be a higher paying job and finally, cable trenching just sucks-ass!
See this post. Nobody is going to "run into" a gable or eve mount pole. Getting a new roof, what do I need to know?
I have done my own installs on my two poles for the different sat dishes twice now in 25 years of having satellite. After 10 years they do seem to rust out and the pole will snap off after a particular storm or a jostling by something else. The first time my pole was damaged due to Hurricane Rita 05 and the last time it was changed out was in 2015 when the pole snapped off after 10 years in the ground. We started with a big thick pole for the Primestar Satellite dish in 95 and it rusted out in 2006 and snapped off when I was trying to remove the old sat dish off the pole.
I was concerned about that, too, at first but I'm a believer now. For one, there is no half-bagging the foam like a lot of techs did with concrete so the correct amount is used on every pole (hopefully). The stuff is strong and it grips the hole, if that makes sense, really well.
A post mount requires a trench and PVC pipe to protect the coax from weed-eaters, lawn mowers and some cases a dog. Also a good anti-spin pipe in cement. Another thing is the dish subject to damage from a grass bagger on a riding mower. Also, if dish is damaged or wire broken, it is not covered by Dish Protection Plan.
