Nobody would think of Cape Town being so hot that we have overheating problems, but it gets so hot here during December - February that solar panels stop working.
ABB make a range of enclosures that are insulated against temperature variations.
We have used the UT7, UT4 and UT10 with great success.
And to put my money where my mouth is. This is what happens to a UT-10 in the event of it being in the middle of a raging fire. As you can see, the PVC pipe into it has been burned to a crisp, but there's nothing wrong with the contents of the UT10.
Here you can see some UT7s vs a Gewiss "208" enclosure. The 208 melted in the heat and the RB ended up fried. The ABB enclosures are still in place today. All I had to replace was the STP and the LMR400 (and a couple of feedhorns).
The enclosures keep the routerboards working when the antennas are covered in snow and when it's 50 degrees celcius on the side of that mountain.
