Grants Pass TV Repair | Radio Frequency Burns From A Long Wire Antenna Supported By A Kite @GrantsPassTVRepair | Uploaded 3 years ago | Updated 2 hours ago
Many of us Ham Radio Operators have discovered what it feels like to get a radio frequency skin burn when accidently touching our transmitter antennas, but how often have you heard about the dangers of touching your receiver antennas output?
In this experiment I flew a kit with wire near an AM radio transmitter, and the length of my wire was 368 feet and 6 inches long. The reason I chose this length of wire is because it was half a wavelength of 1.270 Megahertz which happens to be the frequency of an KAJO Rado just a few blocks away, and due to antenna resonance principles, having the right length of wire based on the frequency you're trying to capture energy from is important.
As I demonstrated in this video. Once my kite was in the air I touched the end of the antenna wire supporting my kite I discovered it gave me painful RF skin burns. Since the radio waves are high frequency the current only burnt the outer layer of my skin because of the skin "effect" of high frequency energy which travels on the outer layer of conductors, and in this case I was the conductor.
If you try this experiment please (be cautious). if your wire happens to touch the power lines or your wire gets struck by lightning you are not likely to survive.
Special thanks to KAJO Radio for providing the RF power for this experiment. LOL.
