Totally! SWR goes from like 1.5 to like 2.5 to 3.0:1. It survived though. Main trick in getting it to survive was it was only at about 1/3 to 1/2 it's max output power and voltage to the amp was low (around 11.8V-12.0VDC) (Lower voltage allows worse SWR handling with transistors like the 2SC2879 as in this case).
NO a standard CB radio has a 4w max TX by law. There is no way on Earth this would happen. This guy is probably pushing 1000+ watts using linear amplifiers etc....
Eric Owens Its a top loaded antenna. The inductance will cause high voltage and low current to be present at the top. The feedpoint of the antenna is high current and low voltage. All antennas have this behavior but because this particular antenna uses a loading coil inside the fiberglass to makeup for the fact that the antenna is less than 1/4 wavelength long, it makes the voltage even higher. Antennas work like tesla coils basically, just not as pronounced.
He needs what I have. K40 BCMAX. Rated for 20,000 watts, supposedly. And I’m just running barefoot with it 😂 not for long most likely, though. Don’t read this FCC lol
@@brickson98m - A 100-watt PEP signal on 75 meters going into my SGC antenna coupler is capable of producing up to 20,000 volts at the coupler's output terminal. That's why SGC supplies a length of high-tension spark plug wire for the output of the coupler to the antenna's feed point.
Use to pull up in front of the bakery at closing to key the mic just after they turned off the front billboards so that when they looked out and saw them still on and go back to flip the switch and check again they were still on, back and forth a few times just for kicks. Kids with a linear😂
Lmfao!!!! I remember back in the days keying up and comming through my neighbors toaster oven 1500 watts through a 102 in my work van, and sittin in front of subway keying up as the emergency lights going off and on and the immigrant sub maker thinking the gods were talking to him and my son laughing his ass off!!! GRIZZ STATE WIDE!!!
I found this video by chance. Can somebody explain what is happening here. My understanding is the "baby babbling" sounds are coming only from the flame? So there is no speaker at all? How can identifiable voice sounds come from a flame? And what is actually burning from antenna tip? Thank you....
Yes that is what's happening. In AM, the amplitude is the modulation so the voice causes differences in the amplitude of the flame - which you are hearing. It's similar to the Tesla Coils that play music.
I think that is a common myth. Can you find me one documented case of where RF can be proven to be the cause of any cancer? I used to think the same thing, but I've never been able to find evidence? There are tower guys who climb towers on an almost daily basis WHILE antennas are transmitting, with still no higher rates of cancer than the regular population.
DANMAN it’s non-ionizing radiation. So there is no risk of cancer. If you’re up around 2.4GHz and transmitting at high power, and you’re very close to the antenna, you could feel some heat. That’s how a microwave oven works. But unless you’re very close, and it’s transmitting at very high power, you won’t be burnt. I’ve heard of tower guys that work in cold climates sticking their hands in front of directional microwave (SHF) antennas to warm them up.
You are right - here's something funny - when there is no fire, the SWR is around 1.8:1 but when you get it to start producing fire, the SWR goes to around 2.5:1. I never blew up the amp and the reason (I think) is that I had significant voltage drop (around 11.8VDC) going to the amp. Lower voltage allows a transistor to withstand bad SWR much better. If you study the datasheet of the 2sc2879 you'll see. Thanks for watching.
us cbers usually only make noises like that when we're testing something, or atleast here in the UK, I don't know about where this person is, since its AM i would assume Italy because they usually always use AM or SSB especially when on the freeband
