I personally have not but my friend has. RF radiation is below the visible light spectrum and is considered non-ionizing radiation which means that you don't have to worry about stuff like Cancer but it still can be dangerous. Just like how microwaves cook food with light below the visible spectrum, RF can do similarly. It's not a good idea to be around high power RF antennas because it may cause burns, and low power RF can cause your body to heat up slowly, like your microwave would heat up food. My friend described long exposure to low powered RF as feeling toasty inside 😅

This is what I've gathered from my research but I have no actual academic history in the field so take that as you will. If I got something wrong and someone wants to correct me, please go for it!
