said by Andy from CA:I may be totally wrong so no flames please. Is this LTE?
Smiley aside, no. It's a just a weatherproof enclosure for copper splices, or a line amp.
Verizon's new service uses their standard LTE towers. The cantenna mounts on your house, not a nearby telephone pole. The concept is that unlike a 4G dongle or 4G/wifi box, the cantennas can be tuned to a single channel on a single tower. This reduces the impact to Verizon's infrastructure.
It's actually a good way for Verizon to leverage the investment they're making in LTE deployments and backhaul. It's not a cable or high speed DSL replacement, but it does fill a niche.
