  The lowest point of the cable appears to be below the box and the box-to-house insertion point. So whether the water drips down the front, or leaks down behind the back of the box, that water is going to drip off that lowest point of the cable just as it would with a drip loop.

    Drip loops are also generally a regulation for ease of repair as well. In the future if this cable needs a new tip you are left with very little to work with and may need to replace the entire run.

      The dipole has a coil of spare coax closer to the antenna feed point, which I think also serves as an RF choke.

      The VHF/UHV J-pole didn’t have any extra, but agree it would’ve been nice to keep a little extra coil if I’d had the option.
