Well now everyone knows its not an SBCA approved surface, its about time everyone knew what is expected of an installer, and how a lot of customers are being short changed on installs, where I come from if you short change someone you could end up with a VERY sore face, or at the very least they would NEVER return to your business or shop, so I take exception to being ripped off. And in my opinion if your installer is not SBCA 1+2 (2 is for multi dish installs like PhaseIII/Dish 500...)certified, VoOM certified and licensed if needed in your state and if they do not ground each and every system to local and NEC code, you have been shortchanged, bamboozled, had, conned, taken for a mug, the urine has been extracted...... You get the message.
