Hmmm... I s'pose you missed my point, but since you don't know me yet I'll address your 'concerns'.
1) Yes, I know the difference. It's easier to say and type 'messenger' than 'attached ground wire'; and you proved that you understood what i meant.
2) Yes, I've installed Superdishes; I've installed 500 dishes; and I've installed multi-dish arrays including 500 w/MC(DP34) and SD w/MC(DP+44).
3) Although I've had situations where I've had a good ground there and installed the switch somewhat near the dish, typically my switches end up in attics or basements. The ground block needs to be bonded with a better wire than that 17ga 'attached ground wire'. I use that to go from the dish to the ground block, but from the ground block I use 10ga or 12ga to go to the conduit; water pipe; ground rod; ETC. All this needs to happen before the switch. Again... it goes: dish, then ground block, then switch-- in that order. Remember, the DP34 isn't UL-rated and can't go in the ground path (that little 'ground lug' is only decoration, you can't ground it). Since it's hard to tune a dish from the basement........That was my only point.
P.S. Nice to meet ya....
