    What I find funny here on the Zed is that he named the thread, "Build your own DX Commander Multifan Vertical Dipole" and people are losing their stuffing over it for referencing DX Commander's commercial product.

    If the post had been titled, "Build your own Multifan Vertical Dipole" people would be blowing this guy off and scoffing that he's a rip-off artist and that a multifan vertical is nothing more than a DX Commander vertical. The Twighlight Zed.

    Not at all.

    See the posts just prior to yours.

    We are hardly bent out of shape, or dare I say....'fractal' from the thread?

    If the tile had read....My version of a Multiband Vertical...... There might not be any comments on the video. I own one of Cals Classics. It's been up for over a year with no issues at all. He supplies s the parts & you build it. In todays socially sensitive world, if everything is not lollipops & rainbows , someone gets offended. How does someone know that what they said or did is not socially acceptable if not for someone else telling them it's not? If that's not acceptable these days, then I am of the opinion that posters are letting "dude" know their opinions. Don't attack them for their opinions and don't attack them for theirs.

    It has nothing to do with that.

    Although Cal has not trademarked 'DX Commander' in the states, it is well known--until now--that the phrase 'DX Commander' refers exclusively and specifically to an antenna kit designed and sold by Cal. If there are then many different 'DX Commander' makers, who call it that, Cal's efforts and products are lost in the noise.

    This is ==EXACTLY== what happened to Mike Traffie, N1HXA, with the hexbeam. Many of you don't even know who N1HXA is, and that he closed his business. All you know is the phrase 'hexbeam'. And the pioneer,IMO, gets shafted.

    W9FFF did a fine job and we just disagree about how and when the term should be used.

    It has nothing to do with language modification. It has to do with identification and recognition.
    When the phrase 'DX Commander' is used in a purely generic sense, it obscures the origin and source. That wasn't W9FFF's intent, and he clearly identifies Cal in the video. But others seem to think they can do what they want.

    We looked at this video BECAUSE it refers to the DX Commander in the title. But it is not the 'DX Commander'.

    For those concerned about recognition, you may want to consider referring to a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array by its full name, Yagi-Uda, and give Mr. Shintaro Uda his due credit. Mr. Uda invented the antenna and his colleague Mr. Yagi applied for a patent for the design without ever mentioning Mr. Uda at all.

    I always do.

    Uda was Yagi's student.

    Good suggestion for everyone.

    Exactly. The fact is that while Cal didn't invent the multi-band fan vertical, just about every ham knows about it. As you said, it has become a generic term now. Reminds me of when people say "Go Xerox this page" as oppose to "Go photocopy this page". Xerox even had an ad campaign that went "Remember, Xerox begins with an X and ends in a TM". They fell victim to their own fame.

    In the video, he gives a TON of credit to Cal and even breaks down the cost to make (which doesn't even count the $300-700 for the 3D Printer) and the cost was about the same and pretty much even said that it would pretty much be cheaper and less of a headache to just go out and buy a DX Commander.

    What I find amazing is that even after several pages people still think that he hasn't given credit where credit was due. I look at these people and LAUGH because I KNOW they didn't watch the video ... because it just wasn't true.

    It was a good video that shows how people can make a home brew antenna ... which last time I checked, was a major part of this hobby.
