    I compared three mono banders 10/15/20 to a Hex Beam, AND NO difference period!

    Here are the details

    10 Meter Force 12, 4 element / 12 ft boom / Mono Bander

    15 Meter Hygain, 3 element / 15 ft boom / Mono Bander

    20 Meter Mosley 3 element / 24 ft boom / Mono Bander

    Versus

    K4KIO Hex Beam

    Hex Beam was up at 45 ft

    10 Meter up at 55ft

    15 Meter 50ft

    20 Meter 45 Ft..

    No difference...

    I tested for 3 months, I still have the Hex beam and mono banders

    Bottom line, Unless the boom is 32 ft, buy a Hex beam (K4KIO or something like it)

    I had Ham operators come to my house to witness

    No matter what the configuration, Steppir, Optibeam, Hygain, or what ever, if the boom is less the 32 ft, you are wasting the money..

    I tested, retested, and tested...I am sorry if the software analysis does not come with the same results.

    I have no investment in K4KIO, nor have I ever met the owner..

    I still have the Hex beam and mono banders, if you go to my QRZ page, you will see the set up

    Cheers

    exc for, reactive near fields. Light bulbs don't have that ... Also, antennas have distinctive patterns (like nulls straight off dipole ends, directly above a vertical), light bulbs can have shading owing to filament 'support wires' (and other structures) internally ...

    Additionally, antennas often end up being a fraction of a wavelength, and E-fields are very intense off the *open* (like with a dipole) ends. Light bulb filaments are many wavelengths (of light) in size ... I'm seeing more differences than similarities, exc for a few areas ...

    Perhaps the "powers that be" at the arrl HQ need to understand this concept, They seem to think that giving increased operating privileges with out any further testing is in order.

    While I agree that physics learn'in is a GREAT thing, ham radio is a HOBBY and not a profession. I got into the HOBBY when I was 14 and that was my entry into my telecom career.
    Maybe there should be a college ham radio profession degree.... I think not.
    Even a lot of pro RF engineers would find it not easy to design and build radiators from scratch. They know how them radiators work but without professional test equipment, helpers and other stuffings...ain't so easy.
    Ya ain't gotta be a chemist to bake a cake! Baking and cooking is a lot of chemistry going on in them there heating apparatus thingies.

    I can see by your reply you got the jist.

    The principle physics is really simple and deep understanding is won with even a very short effort.

    Ham radio is not a hobby; in the US it is a service, and the defining aspects of the service include 'enhancement of the radio art' and 'pool of skilled operators'.

    The reasons there are many 'physics' questions on our exams is that this is fundamental knowledge we need--and by law must have-- to use Part 97 privileges.

    What worries me is NOT that most US hams don't want to know the physics deeply--hey, that's ok!-- but that the culture of ham radio today is AGAINST such understanding.

    Saying 'physics doesn't matter' is a code phrase for 'its ok to be uninformed'.

    If you have a US ham license, you learned some of this physics whether you liked it our not, in order to pass the tests. No reason why you can't like it FURTHER on your OWN terms, not one imposed by a teacher or a school or anything else. Certainly not by me!

    But don't let someone else tell you the physics doesn't matter :)

    If futzing around is a good way for you to manifest your own curiousity, then that's fine!

    If putting a metal shopping cart in a tree as an antenna (for example; its on the internet!) gets you to think and learn how antennas work, and how to make yourself a better one, then more power to you.

    Ham radio is a hobby worldwide. The only reason it is a "service" is because that is how the FCC divides all of the radio allocations, into "services". Such as GMRS, FRS, ARS, Maritime service, etc.

    Yep. Its a service. And it a service which requires working knowledge--including some basic physics--to attain. That's wasn't meant as a convenient cubby hole. Its a gating item to be a member of this service.

    Use of the service for personal enjoyment is certainly a big aspect. But I have yet to see a hobby which 'enables' it's impassioned to be stupid.

    Stupid is not ok.

    If you want to use a FRS radio to have a blissful ignorance of any physics, well, that seems a logical enabler. But not Part 97 ham radio.

    Or, use of the hobby to provide some sort of service is certainly permitted, as long as that service falls within the definitions and bounds of the hobby itself.
