    Theorists v Empiricists

    On another forum I read with interest a debate that started from another homebrewer asking whether someone could tell him the diameter of the 10k antenna shaft. However, soon enough the thread split into two camps that reminded me of the battle between the geeks and the jocks in High School. No one was really answering any questions by that time; simply ridiculing each other: name calling, etc.
    The scientists of antennas vs the machinists without a clue (not my idea/words) were at it and I wasn't learning anything. . . so I asked for some answers twice, 24 hrs apart, and seemed to be ignored.

    This forum, WWRF is an incredibly informed, very helpful forum who seem to have a lot of interest in understanding antennas, and in sharing that knowledge. I hope I'm not rubbing a empty genii lamp at this point, but I want to repost here my request and see if there are any intelligent responses forthcoming.

    Thnx, Homer

    I like debate, it's healthy, but it should ultimately result in answers. I hate to be wrong, but I like much less than that to be stupid, and stupidity is easily defined as the cultural phenomenon of being unable to learn rather than the physiological incapacity to learn. In other words, I don't want to be stupid, so if there's any way you can intelligently save me from either mine or anyone else's stupidity, please do. :blink:

    Hello homer BB,

    I fully am with your point of view in behavior of people.

    And although im at least 8hrs a day busy with antennas if there is one thing i know is that i certainly do not know all...

    So, guess you have many followers along with your point of view.

    Reading through your post...trying to help lol... i only managed to find 1 question....
    Perhaps there were more, but my lack of the langue migth be the problem.

    quote; Ok, the point is that no matter where one is in their knowledge of what makes an antenna work, what we know is what we hear on our stations; more or less from our antenna. Or am I wrong?
    end of qoute.

    Yes you are rigth....
    If for your purpose the antenna does what it needs to do it is the best for sure.
    The problem comes with two things:
    At first the antenna will not do that all the time, you need to have a "known" starting point to wich we all can refer and often people are not willing to lisen to things like that...
    The mind is set: "the antenna is louder at my neighbour...end of story."
    For example there are a view videos of the sirio gainmaster in Europa with European sproadic E propagation. Everyone is impressed with the big signals etc...
    But if you knew that sproadic depends on high angle TOA it would be so fancy anymore..

    Secondly, often people start speaking about this is better etc in comparisment to that etc...Often antenna 1 is changed to antenna 2 but perhaps also the coax is renewed etc..
    A 1/4 ground plane can outperform a 5/8 wave vertical for Dx...but does it have more gain...no...
    So you need to get those things straigth...what are you searching for...
    You need to have some background information some basic knowledge about antennas.

    Secondly, i have actually constructed hundreds of antennas there isn't one who was different for theory. If theory says it cant be done....it can if not it wont work.
    Surly it can happen that people without theory construct something that works...
    But if that was the case it can be backed up by theory.

    I have seen "respected" antenna manufacturers making many mistakes.
    You can actually fill a day job getting into arguments on different forums.
    Getting foolish arguments...

    Not saying that i havnt or wont in the future (make mistakes)...but at least im pointing out as you are the willingness to make one.

    What i am confident that there are better ways to go to just change things and "hope" for the best...that not a efficient way....
    The worse thing is you cant back anything up...the only thing you can mention..."it works great!" now, why believe that while everything can be explained.

    Kind regards,

    Henry

    Thanks, Henry.
    You read the post right. I guess I was only letting a little steam off.
    I see the points you made, and I agree. I know the best place to start is at a known and true point of science, and just trial and error leads to more frustration than success. Because I am so new to seeking understanding I get a little frustrated when those who know would rather argue about their different perspectives than teach from their common understanding.

    What I wanted from them was to find out through scientific theory why the antennas that were built by someone who wasn't supposed to know what they were doing were working so well. No one arose to the challenge. . . and so another learning opportunity seemed lost. I guess i wasn't too clear :confused:

    That's why I really enjoy the threads on forums like this one. Someone always takes the time to look for the real answers, and share them.

    Thanks again.
    It's just good to be here.
    Homer
