Maybe this must have been asked several times (in that case I apologize)..but what do I need to install a superdish on a pole. The current option I have is to install the mount to a 4x4 (part of my backyard fence) but given that the mount for the superdish is wider than the regular 18" dish, the 4X4 may not be wide enough. Another option is to attach a 6X2 piece to the 4X4 and mount the mast on the 6X2. Or use a galvanized 2" dia pole (using quick cement) and mount the dish on the pole. Which one is preferred? In all the cases the height is roughly 5-7 feet (the fence is ~5ft high).
