Lanai TVs by the water in Land O' Lakes: lake humidity, the pool cage and the GFCI
A lanai on a Land O' Lakes lake lot gets used through the long warm season, and the TV out there lives in lake humidity. The mount belongs on the block wall of the house, under the roof, never on the aluminum of the screen enclosure or pool cage, which is built for screen panels and wind, not a hanging TV. The installer drills with a hammer drill and a 3/16-inch bit, fills each hole with sealant and drives 1/4-inch Tapcons, with coated bracket hardware so the damp air does not rust it. The set stays where the sun never lands, and anything in direct light should be outdoor-rated. Humidity also means outdoor-rated cable jackets and connections that point down so water runs off them. Power comes from the lanai's GFCI outlet, and that outlet matters: a summer storm can trip it, and the outdoor TV goes dark until someone presses reset, so the installer shows you where it is before leaving. A covered patio without a screen is the same job with more wind. The lanai wall is block, so the +$99 masonry surcharge applies. Lake-lot lanai installs run 75-100 minutes.
