I'll bite:
First off, that's a solid piece of EMT which goes into the cover of the W/P box;
No supports visible for the EMT or the box;
Sealtite to the mushroom fan not supported.
edit: Oh, yeah, and that sealtite looks to be more than 6 feet long, too.
As a side note, the nice coils in the ground wire to the antenna will make a great choke coil to any lightning currents.
