Pole size for pole mount install

I saw a nice looking, 6x6" wood post, painted almost the color of the Dish. Looked good in that particular yard.
 
I recently moved into a new house. The previous owner had a slimline directv dish. The slimline was on a 2 3/8 pole (I believe). I currently have a 1000.2 rigged onto the 2 3/8 pole. Every time the wind blows hard I loose signal, and have to correct the dish. I was wondering if anyone knew of an adapter to "downsize" a 2 3/8 pole to 1 5/8 OD for the 1000.2 . Thanks in advance for any suggestions.
 
there are pole adapters, however the thin walls of the direct slimline mast (mount) wouldn't stand up to the leverage long,best bet is to mount a new mast
designed for 1000.2 (1 5/8")
