I made my own brackets from 2" aluminum angle stock. Put bed of dicor sealant, and screwed brackets down, covered all with a layer of dicor. For wire, I drilled hole in roof over an interior wall and ran a length of flexible blue conduit from roof to basement inside the wall. On roof for entrance to conduit, installed a plastic exterior junction box, imbedded in a layer of dicor; screws holding it to the roof inside the box.
Its only been a year, but there is no indication of leaks, and last inspection (couple of days ago, getting ready for the road)left me with no concerns.
Regards,
Doug
