The Lake Marion side: lake-lot moisture, a sloped cable hole and fasteners that will not rust
Lots on the Lake Marion side of Poinciana sit close to the water, and the air under a lanai roof there stays damp. Moisture changes three things about an outdoor TV. The fasteners come first. Plain zinc-plated lags bloom with white rust within a few seasons near water, so the installer uses stainless or coated hardware and sets each one in exterior sealant. Then the cable path. Any hole from the lanai through the block into the house is drilled on a slight downward slope toward the outside, so water that finds the hole runs out instead of in, and the cable gets a drip loop. Then the TV itself. An ordinary indoor TV inside a screen enclosure on a lake lot collects condensation inside the panel, so the choice is an outdoor-rated TV or a fully shaded corner with a cover. Four Tapcons set the bracket into the block of the house wall, under cover, with the +$99 masonry surcharge. The outlet has to be GFCI-protected, with a bubble cover that closes over the plug. Lanai installs on the Lake Marion side run 75-100 minutes.
