    I am just amazed a average human being able to make a custom antenna with information you can find online and library sources. What amazes me is a two of the main makers of antennas for the whole world cannot make specialty antennas. Yet they were able to make them years ago. What makes my day you just take on a challenge "Head On " Sir.
    Peace to you and have a Happy New Year too !!

    I look forward to see more great antenna videos from you Sir "On my workbench". Nice job fella too.

    Beautiful antenna. I'm getting ready to try to duplicate it. The online calculator does not say much about the dipole. It gives directions for a folded dipole. I might have to use that. It looks like you used a straight dipole, but it's not a full wave. It looks like you have it divided with the insulator. Could you give some details on the lengths you used? We sure appreciate you!

      Hey4883,
      If you are trying to receive a station on RF CH 36, 605 MHz please hold off on building the Yagi, after WTVF CH 5 changed from RF CH 25, 539 MHz to RF CH 36, 605 MHz, I have not been able to receive their signal my Yagi antennas are DEAD on RF CH 36, 605 MHz, I designed my antennas for RF CH 36, 605 MHz and they worked outstandingly when WTVF was on
      RF CH 25, 539 MHz. I have been working on finding the problem for a month, while I still don't know what the problem is I do know what the problem
      is not, as everything that I have tried and I have tried a lot of things, have made no improvement. I have order a Nano Vector Network Analyzer to test my Yagi and try and find out why they are DEAD.

      I have found a deferent Yagi Calculator that provides more parameters and does provide the dimensions for both straight and folded dipoles.

      I will get to the bottom of why the antennas work on RF CH 25, 539 MHz but not working on RF CH 36, 605.

      @@onmyworkbench7000 I have completed the entire stacked antenna except the dipoles. I'm still studying that. If you figure out anything I'd appreciate the info....Thanks

      I am still waiting for the Vector Network Analyzer to get here, it's coming from China and taking it time getting here. I will let you know as soon as I have a solution. It works for other frequencies but is dead on CH 36, 605 MHz.
      Did you use the Yagi Calculator www.changpuak.ch/electronics/yagi_uda_antenna_DL6WU.php
      Please post photos of your antennas.

    Sir :
    I may be preaching to the choir, so forgive me if that is the case !
    In regards to element diameters, you can make your yagi's more forgiving by increasing the driven elements diameters, essentially making them fatter, for lack of a better term.
    Allowing greater band width, which may be beneficial to the " Hop Scotch "
    methods the FCC seem to be using to allocate frequency use to the highest bidder !
    As I said in an earlier text, if you don't, I think a good preamp would be very helpful.
    As you likely know, feed point impedances play a critical role in the success of antenna playing, or not !
    Especially with the new digital modes employed in television today.
    It is either " On ", or,
    " Off ", with little to no forgiveness with regards to inaccuracies !
    Thanks for your consideration.

      I would love to know the answer to the larger diameter element size Sir. Thanks
