BM, I don't know what maco's boomer GPK predicts in better performance, but my models where I changed the angles for the slanted down radials seemed to make a notable difference in gain. The difference was not Earth shattering, but the horizontal radials appeared to be better.
Can you be more specific about what you think Bob posted. I read that saying in quotes as Bob telling us what Cebik told him on the issue of slanted radials not making much difference until we slanted them up..... Here is the full quote:
I didn't see Cebik's quote as saying anything on my specific issue, about the Imax GPK radial angles. I'm interested though, and I will go back and re-read the thread. These were just models of a 5/8 wave un-matched, end fed radiator, with radials that I had on file. I just changed the angle from very steep at 20*, then to 45*, then to 30*, and then finally to horizontal at 0* degrees toward the horizon. I was surprised at the results too.
You might remember I was trying to justify what Tech 833, reported in his field testing of the Imax GPK, and I was very surprised to find he was right.
Let me try and explain this to clear up any confusion you might have on what I said compared to what Bob posted for us, that Cebik told him. I thought Bob was quite clear in what he posted, and I just read Cebik's quote differently than you.
So, go back and look at what exactly my recap below indicates, at 40', 65', 36' feet. I did the recap to help the reader better understand what I was trying to do, and what I saw in the models, not trying to mislead them.
Bob told us that Cebik told him there was little difference in the angle of radiation. I highlited that in his quote above.
BM, in my report I was talking about the gain difference that Tech 833, reported. I said nothing about the maximum angle of radiation, in fact my recap shows, with the exception of one report which was probably a mistake on my part in selecting the angle for the model, there were no changes in the maximum angle of radiation, just like Bob posted to us that Cebik reported to him.
See again BM, it's as I've said before, it is usually a problem when folks just look at the pictures, and don't bother to read the captions.
But not to worry, I do it too. I make my remarks about looking at pictures in order to help make a point about what we look at on the Internet sometimes.
Here is my recap:
