New insulated enclosure for our UHF DMR repeater

Over the past week, I constructed an insulated box to protect and to warm our repeater during the winter months. It was good timing since the temperature dipped to – 20 F this morning. To heat the enclosure, I used a 100 Watt lightbulb. After being closed up for about 2 hours, the internal temperature was 50 F.   I also installed an internet switch to act as a buffer between the Motorola SLR 5700 ethernet port and our ISP.

Here is the box all closed up and set for the rest of the winter.
