Radiation Patterns vs Power level

[koØm]

I am not an expert but I believe the answer to this is "no."

As far as 'overshooting' goes, that has more to do with the takeoff angle and, to the best of my knowledge, an antenna is going to radiate with the same pattern regardless of the power applied to it; the only thing that changes is the density of the electromagnetic field.

That's one vote for "Science"

All with 200 watts...
If i use 1000 watts in the same antenna my reports go up in the zone my skywave reaches down, the dead zone itsself changes hardly, the higher field might in fringe area's become just clear, but the dead zone doesn't change, further out after morre hops i found that the dead zones become less pronounced using more power here, maybe because the reflection from the skywave scatters more.

I also have the OCF antenna here which with coil and added wire is resonant on 160, and just at 45 feet up is a skywave NVIS antenna for 160.
Totally different pattern, good for Europem bad for DX.
But it fills in the first and 2nd dead zone nicely, so using both antenna,s in Europe i can cover the field without dead zones..

Same goes for more power, i expect from 200 - 1000 watts to see just under 1 S point change for the better, sometimes that is a (lot) more...
Maybe the refraction is better using more power as just keeping in account the extra power.
Sweet spot is about 600 wats power, the difference between 600 or 1000 watts is mostly never rewarded in signal reports.

That's two votes for "Science", the more "NVIS" properties ("Near Vertical"-higher radiation angle) a so-called Shoot-Out antenna has, the higher the density of signal will bounce back locally (versus an antenna with a lower radiation angle).

CB is laugh city and this is no exception. There is no such thing as too many watts overshooting the target, have you ever heard of a shootout? That's when mobiles gather in a parking lot or field, set up monster antenna arrays on the roofs of their vehicles and two line up to shoot at a target vehicle downrange.

You, are tellin' me? For more times than I can count on both hands and feet in the last 30 years, I've heard the same excuse about "Overshooting" because of watts (usually by the loser) expressed by someone. That's why I brought this subject up, if there was a plausible explanation, it would be in antennas.

The loudest signal wins, that is to say the one who stomps on the other. Of course there are super power amps and heavy duty alternators driven at high RPM by hemi engines, sometimes sparks fly and antennas go into melt down.

You are talking about the "Lex-a-dyne" (Electrodyne) Alternator and the legendary 383 Stroker Engine. I've seen the aftermath of one those alternator fan coming apart; miracle that no one was injured, shrapnel tore a hole through the hood of that truck like a Hand Gernade.

I couldn't find the video I was looking for but you might find this interesting. Notice the herringbone pattern caused by the intense RF field:

Like I said, I hang out with the fellows once or twice a year and it's always the same stories and explanations, I've suggested that they do antenna trials and also offered my opinion on the QRO vs QRO showdowns and, of course, I was wasting my breath.

I would have done a better job proselytizing my Prostate Gland as, they had already done a great job of proselytizing their own.

Food for thought: I know that studies say the RF energy below a certain frequency doesn't affect the body but, we all know how unfiltered those devices are; I once heard one of the locals on the TV band as well as around the high end (108 MHz) of the FMBCB. The DC "Sky's-Da-Limit" champ passed last year of Leukemia after many year of RF exposure to scores (as in "Four Score" and seven years) of kilowatts enclosed in the Faraday shield of his van. Go figure, if a warning label on a pack of smokes doesn't deter cigarette smokers, why would an operator stop doing QRO shoot outs even if they know it is dangerous?
