I agree, the Florida, Arizona heat problems destroy most outside use electronics. This is especially true of products designed and used in European countries. They do not take into consideration that in today's global market (think Amazon and Ebay), products designed in one market will be sold and used all over the world. As buyers, we need to take this into consideration as well. If it works in Europe's cold harsh climates, doesn't mean it was designed for Florida's heat, rain and coastal salt laden air.
These things need to be taken into consideration by designers and buyers alike.?
That being said we own a plethora of DC cooling fans for use on our various electronics here in Florida.

I am on my third Wellbrook replacement loop head. It appears that the potted resin is not only keeping water out (amongst other things) but seriously keeping heat in. The heat buildup in Florida is upside of 100F. When operational, the resin heats with the current flow through the ferrite (like an immersion heater). Due to the temperature expansion differential between the components (esp ferrite) and the resin, mechanical forces appear to be cracking the ferrite and the tiny wiring transformers inside the head. So if your loop head has failed similarly, you will notice zero signal suddenly as the RF comes to a dead halt. Confirm by checking the resistance across the the loop leads which will be >1k. I can only appeal to the manufacturer to cease the process of potting or offer a lifetime replacement guarantee.
