You will not see the problem until a few seasons down the road, and you dont see the problem because you never paid to sit in a SBCA class for eight hours (then passed online test), and the trainer telling you not to mount on wood posts or you will be back charged, SBCA,s guide lines say a wood post IS NOT AN APPROVED MOUNTING SURFACE, seems the installers in your area are not SBCA 1+2 certified...shame, pretty soon they will nor be getting much work! The Problem is wood bends,warps and twists over the years, the only time it is permitted is where the post is attached top and bottom (like on a deck) And yes we guys do everything by the book, we call it .........SBCA certified 1+2, if a DirecTV installer installs in this fashion they could be backcharged if a HSP inspector comes across it For your info, I do not make the rules I just follow them to the letter! Plumbed and on a metal pole is a MUST for a Phase III dish, (IMO) as it REALLY helps get a great signal on all three satellites, all you need to do is read the manual that comes with the dish, maybe thats your installers problem!
It would be VERY easy for me or any installer to mount a dish on any surface a customer wants, but SBCA certified installers dont install on wood posts because we want the customer to have YEARS of uninterrupted TV, and we dont want to have to go back every few seasons, it cuts down on service calls, OK now lets hear all the hack installers tell us why they throw satellite dish on any surface, or the guy from a few weeks ago that wanted to race me on an install : ) I am not the quickest installer in the world, just one of the best! If anyone tells you any of the above ask to see their SBCA 1+2 card or license, I carry mine in my truck at all times!
