First, from the front:
We are not at this stage designing a shade, as we figure that they can be easily made by users from whatever they have laying around, for example, an old plastic bucket, waxed cardboard box, or even a drink can split open.
The main thing to see here is the curved back to make it easier to strap to a tree or pole, and the ribbing to help provide at least a little air-flow between the unit and whatever it is attached to.
Here you can see the D-SUB 15 utility/IoT and D-SUB 25 power/radio connectors. Also, below those you can see a couple of round markings which are drill guides in case you want to get ethernet out. In their default state, they have gortex moisture seals to allow the unit to maintain equal pressure with the outside, without filling with condensation.
The inside of the top:
Here the main feature to see is the notch and paddle to help hold the PCB firmly in place, to minimise the effects of vibration, e.g., if a unit is mounted on a vehicle.
The PCB itself will sit inside, with fly-leads to the antennae, as shown in the remaining images. Returning to the thermal properties, the main means for heat to exit from the unit is conductance through the antennae connectors. Not ideal, but when you are making a sealed unit that you don't want to cost thousands of dollars per piece, your options can be rather limited.
