I installed my SK-1000 on my prior 5th wheel myself. It had an Alpha roof system which recommends using Alpha sealant products. I didn't know at the time so I used Dicor non-leveling lap sealant as the main bead of sealant under the base of the antenna, and Dicor self leveling lap sealant over the top. Seemed to work fine on the Alpha roof.
I did put a roller plate on from Winegard - SKA-004 Roller Plate
Looking at the SKA-004 roller plate I think I can fabricate something similar our of some sheet aluminum that I have. Instead of putting four new holes in the roof I'll try just adhering it to the rubber roof with the Dicor. Thanks for the info.
I wondered if an electrical 4x4 cover plate wouldn't have worked just as well - agreed, but Don makes some good points above on using something not rigid.
Just a note on the full plate that Winegard also offers (SKA-008} - they are a) expensive, b) work well to cover over old work on a flat fiberglass roof motorhome, but c) they enlarge the footprint of your antenna and on a rubber roof with any crown to it (curve for water runoff), they don't do well because they don't conform to the crown. To secure that plate down to the roof, you are actually pulling up on the underlayment to force it flat like the plate. If you walk near the antenna afterwards, you run the risk of pulling a screw or separating that lap sealant because the underlayment will want to lay back down from your weight and the plate won't let it.
Just my experience - .
