The words weren't meant as fighting words, more an observation of what you actually said, but I guess they could be mistaken that way, especially if you are attached to the mis-information you post as absolute fact. Really, I have nothing against you personally, and if I were intending words to be fighting words, believe me, I wouldn't limit myself to something as small as that. Honestly, this exchange with you is more humorous than anything... If I didn't find what you were saying so humorous I would have stopped at the point of telling everyone to do their own research on the matter, which, for the record, I still say people should do their own research on this matter as I know the conclusions that such actual research will bring about...
But call my experience "so called experience"? OK, lets ignore my experience. Have you looked online at others experiences? There are some right here in this thread that clearly disagrees with yours. If your experience disagrees with not just mine, but pretty much EVERYONE else's as well, who should I believe? For the record, that "EVERYONE" is including several people who have demonstrated a level of knowledge that goes far beyond yours. You haven't said anything that shows I should trust your experience, which I have to take on faith, over anyone (no EVERYONE) else's... Or do you consider everyone else's experience that disagrees with yours "so called experience" as well?
In reality the V5/8 antenna length is pretty close to being right in between a 1/2 wavelength antenna and a full 5/8 wavelength antenna. Its actually closer to a shortened 5/8 wavelength antenna as it is noticeably closer to the 5/8 wavelength length than the 1/2 wavelength length, so in reality it should be called a shortened 5/8 wavelength antenna (and honestly, only slightly shortened at that). Unless of course you are trying to manipulate peoples opinion of the antenna to get them to think a certain way. In the end you can call it what you will, that doesn't make what you choose to call it correct in any sense of the real world.
When it comes to angle of radiation, you still haven't answered my question of how much of a difference this angle makes in your mind?
I can tell you that, unless you have the antennas mounted essentially on the ground that the difference is less than a degree, and that is going from an end fed 1/2 wavelength to a 5/8 wavelength antenna. I can also inform you that the antenna's tip height has more to do with this angle than anything else, including the antenna's length (at least until you pass a critical length threshold), assuming you have fully choked off common mode currents. Actually, that is where most of the difference of the 5/8 wavelength design comes from, at the same mounting point you get a higher tip height, and thus a higher current node. It is also the principle that various other antennas, such as the Astroplane, for example, function on. They are intended to have additional mast sections to elevate them to maximum tip height, essentially to match the tip height of other antennas, and there are many fans right here on this forum, including the most prolific antenna builder that posts pictures this forum has ever seen...
When it comes to the need for radials, I have news for ya, a 5/8 wavelength antenna does not have to have radials to work well. It is actually possible to get a 5/8 wavelength antenna to work nearly the same without radials as it does with, to the point that you will never notice the difference. You could just come out with something like "radials are always better", and I don't necessarily disagree with that remark, however, how radials help the antenna is greatly misunderstood, even by many who call themselves experts. Lets see if you know, not that I expect you to answer a simple question when you haven't answered previous simple questions... I wonder why that is...
So tell me this, what is it that radials do specifically for a 5/8 wavelength (and ironically a 1/2 wavelength end fed as well) antenna that makes them a benefit to the antenna? Don't just say performance, you need to explain how the radials benefit the performance of the antenna. Lets see if you can do it, or if you will just ignore another question that you can't answer...
Here is a challenge that I highly doubt you will take up, but I'll throw it out there anyway. Make yourself a center fed half wavelength antenna and mount it at the same tip height of your 5/8 wavelength antenna with no conductive mast next to it. They make fiberglass poles that are long enough and strong enough to support such an antenna. I bet you would be surprised at how well it performs, if you would actually bother to do it...
