DO NOT TRY THIS.
Seriously.
That out of the way, we devised a test to see just how dangerous the RF energy can be on an AM tower, if someone were to touch it while it was transmitting.
This tower was operating under 10 kW. There are many AM towers broadcasting at much higher power levels, so they are even more dangerous. RF burns can kill, and there's a reason there are fences around these towers.
Hopefully we have satiated your curiosity with this video.

I wonder how it affects the output power of the transmitter (and the reach of the signal), when you essentially short the output through a hotdog to ground? I'd imagine it must reduce the range by quite a bit as you're draining that power away from the antenna

Reminds me of those stories of people detecting powerful AM signals with their teeth fillings. My physics prof told about when WLW was broadcasting with an effective radiated power of a half-million watts: 1) Ohio drivers on US 42 would go past the tower, and start detecting AM via rusty junctions between body panels of the vehicle. Imagine cresting a hill late at night and hearing a radio hellfire preacher. 2) ionospheric skip propagated the signal to rural Canada whereupon chicken wire would catch the signal and rusty contact points would detect the signal. This interfered with egg production...

@@lazarus908 RF is not sound, it's electromagnetic radiation. The radio tower is a very high voltage, high frequency electrical source. The sound in the video happens as a consequence of the air ionizing with the same amplitude fluctuations as the audio signal (audio frequency) present on the AM carrier wave (radio frequency), so you hear the audible component that's normally demodulated by an electronic radio as the hot dog is burned by hot electric arcs. The sound is the pressure waves emitted in the air from the arcing event.

In Poland we had a massive AM mast which had been the tallest thing in the world back then, before Burj Khalifa was built. It collapsed years ago unfortunately, but they were pumping over 1 megawatt of energy through it! There was a 110 kV high voltage power line to even power up the transmitter and all the facility around it. Imagine shorting out that thing! People living in vicinity said the mast literally played the radio station when it was humid. It was actually the stabilizing ropes, which had some insulators on them. When it was really humid or one of those insulators failed and an arc formed, it was screaming so loud you could hear the radio station even 10 kilometers away!

Back in 2002, I made my professional practices at a radio broadcast company here in my hometown. I visited one of the company’s AM transmitter facilities… was my first time inside of an AM transmitter facility. Then I noticed the antenna area was surrounded by a second fence… so I ask the chief engineer if I could have a close look to the antenna, but he told me about the danger of being near and if I touch the antenna I could get fry…. Didn’t believe him until he took a test rod and approaching a large leaf with the rod, the leaf started to get burned as talking…. A talking burning leaf touching a 50,000 W AM antenna…. Just amazing! Was the XED 1050 kHz AM in Mexicali, Mexico…. So, friends and viewers… the talking hot dog is not a trick… just as the talking leaf I saw ( and heard) it is true. Regards! 👍👍

I know there are folks that do manual inspections on _live_ power lines (getting dropped off and picked up by helicopter), they use conductive suits (nomex/steel fiber) and make sure it's properly bonded to the line before they get on it to avoid arcing at contact points. The scariest part is getting on or off, since they first have to bond the helicopter to the power line (which sounds like a helicopter pilot's worst nightmare), then bond themselves to the power line and move over to it, unbond themselves from the helicopter, and finally unbond the helicopter from the power line. This keeps the lineman safe since arcing only happens in the first and last steps, when bonding/unbonding the helicopter (using a long metal rod for initial and final contact).

Got some questions about supported AM broadcast antennas. #1) Why are the three guy cables broken up into sections of different lengths with insulators between each? #2) I've heard the terminology 1/2 wave, 3/4 and full wave. Can you explain to me how the physical lengths of each are determined and the ground plane? What fraction of the full wave length are the antennas typically? What determines the length of the wires in the ground plane buried in the ground around the antenna? How often does the ground plane need to be repaired or replaced. I love your channel! This new world needs to know how valuable AM broadcast radio has been to the world and about the technology that has made it possible. I listened to short wave radio (fastly disappearing) when I was a child. We had an RF/EMP vulnerability test site in New Mexico that used high power Continental AM transmitters. I'll never forget the driver and PA sections to those things. Thank you for your time!

The medical field still uses this same principle for cauterization. The classic Bovie CSV uses vacuum tubes & spark gaps to produce the RF to cauterize. It is powerful & could even cut underwater.

I worked at a 5 kW AM when I was in college in the 1960s. We did climb on active towers to change bulbs, etc., but the carrier was cut long enough for the victim to get up onto the tower, away from anything grounded. RF exposure? Not a thing then (and probably it shouldn't be today, at AM frequencies anyway).

The sharp edges on the cut end of the wire are "grounding" to the air without arcing. I forget the principal why, but that's why basic spark plugs have a little puck with sharp edges that evenly wears, and you have to replace them once it's slightly rounded. Arc gaps and TIG welders control this with a sharp pencil shape at different angles.

The E-Field is strongest around the sharp points of conductors that are highly energized. It's why you see lightning rods shaped to a point at the top. With high enough power on a sharp point you can energize the air into a glowing corona, or St Elmo's Fire.

Yikes. RF burns (and RF radiation exposure) are no joke. There's rightly a fresh focus on RF radiation exposure when risk assessing ham stations, at least in the UK - more important at higher frequencies. At any rate, I don't think you'd even find me inside that tower enclosure! 😳

One thing that we didn't really make clear in this video (though we may do a follow-up!) is how we planned for the video, and how even with the planning there are still plenty of risks that make this experiment dangerous. There's also a lot of information and formulas for safe RF exposure limits for workers who need to enter higher-RF environments (like the inside of one of these fenced-in areas around a tower base!), and for anyone who would ever want to work around towers-you should know all that! (Especially if you're replacing lights, mounting antennas, etc.)

I've been lucky in that I've only been hit by RF burn once, and it was low wattage. I'd recently trimmed a counterpoise wire for one of my HTs because I'd moved it from the base of the antenna to a belt clip screw and had to compensate for the increased distance to the antenna. And when I trimmed it a tiny portion of the wire remained poking out from the silicone insulation. A few days later I was holding the HT, about to start testing to see which repeaters I could hit, and thought nothing of the counterpoise touching the inside of my arm. Then I keyed up and got zapped because that tiny bit of exposed wire. 8w doesn't sound like much but it felt like a white hot needle going into my arm. The end of that wire now has shrink tubing. ;)
