Making low voltage prettier/weatherproof?
I'd slap up a 6&quot; box, maybe PVC with threaded entries, and then use weathertight screw-in cable clamps to bring each data cable into the box.
And I'd either glue and caulk the back of the box to the wall... or have conduit go through the wall from that box, and fill the rest of the hole.  My concern is animals or insects using the hole as a superhighway.
