I agree 100%. There is no point in the certification unless everyone(providers and Installers) get behind the SBCA certification and make it mandatory for all installers(Subs and In-house)Why bother, you threw your money away when you got certified the first time!
The problem is that any Joe six pack can say he is a satellite professional and can be out tomrrow installing Dishes. Until the providers make certification a requirement, then there is no point getting certified!
