Good to hear!! Hopefully we will see a post from you on Sunday stating a successful install.
We are in the same market and I don't remember who did our install as I was at work. Mine is roof mount as you know.
On the other hand my father in law just had Directv installed at the camp house he rents by a private lake and it replaced a DISH dish, on a pole mount. The installer had no issues with that.
Just depends on the situation ...
If the dish pole mount is the same size as the D* pole requirements and they have LOS, theres no reason Not to use the existing pole mount.
