From GPS World. The link is to a very big file but it is interesting. Radar’d Out: GPS Vulnerable to High-Power Microwaves Commercial GPS equipment, often present in military applications, is not designed to survive in one of the world’s harshest electromagnetic environments — the topside of a modern naval warship. One ship’s radar can often disable another nearby ship’s GPS antennas

They called them RADAR ranges

when I was a kid. I think they are called microwave ovens now. So putting a GPS (read UHF) antenna in or near a very high power microwave oven makes it malfunction does it. Try standing near the focus of a radar dish and see what happens. That is how they found out the microwaves heat stuff in the first place. The tech guy working near the dish focus had his candybar melt in his brest pocket. He is dang lucky he didn't get his head fried. My radar is up as high as I can get it and I don't care if the rolling of the boat makes it perform badly at least my family and I will not get tosted.

Now there's an idea.

Just had an idea for keeping the crew warm in the cockpit during winter sailing!
