    Awesome build and design.
    Appears to be UHF optimizsd.
    New version with Vhf Hi elements added?
    I assume you could use treated lumber similar to that used for decks, for weather resistance.

      Most of my antennas are designed for UHF reception, as that is what a majority of US TV stations are broadcasting on. Here's a link to one of my VHF add on antennas - ruclips.net/video/eqDwqveTOaE/видео.html
      Sure, you can use treated lumber, but I prefer PVC lumber as it is more stable and will not absorb moisture. Thanks for watching.

    Absolutely stunned by how well this works because of how many trees are on my property and it’s only elevated on a 6ft pipe. I also can’t believe how inexpensive and relatively tiny this antenna is compared to the 7 ft, $200 monstrosity recommended by Televes. Not sure if 1/2” hardware cloth would improve reception, but 1/4” is what I had and seems to be just fine for reaching stations as far as 53 miles away.

    I used this antenna design and used your twisted galvanized steel wire idea as well. This provided outstanding results. I am able to receive channels that range between 60 to 70 miles away. This is with the antenna about 16 feet above the ground.
    Thank you so much!

    Would making the one hoop antenna with an extra inner and outer hoop increase the channel getting ability of the super antenna. This style you have made is super because the size factor makes this shine compared to a commercial brand.
    Televes antenna is so large that it looks like an elephant on the roof. One can put four DHA and the size is still under Televes size wise.
    Job well done again MHTI. Would really love to have your knowledge on the field Sir. Peace v

    Excellent detailed instructional video. I appreciated you taking time to go through matrrials needed. I plan on building the reflector antenna this weekend. Currently I'm using a store bought black bar HD antenna about 2" wide and 24:long.., but only get about 8-10 channels and use it indoors. I will try your reflector antenna indoors first ..then move it outside, problaby mounted on a 10-12' galvanized pole
    Will let you know how it works . Thanks again for the video

    A few points:
    All of the dimensions scale with the wavelength of the station you want to receive.
    An important one is the distance back to and the width of the reflector.
    Normally the distance back is 1/2 of a wavelength and the width of the reflector is about 15% more than the distance back.
    Look up the RF frequency for the far away stations. Pick the smallest number
    WaveLength = 300meters / MHz.

      doing the math assuming it did it right that would suggest the reflector by 9.8 inches back for UHF channel 36 which I find to be twice what is normally suggested. Channel 14 would be 12.7 inches that seem way to far. One made for the center of hi-VHF would need to be 2 1/2 feet away. That seems a bit much. Thought the reflector width math seems fine. Could be this works for hoops and different antennas use 1/4 wavelength?

    I am wondering if 2 antennas connected together overload the TV receiver ??? How about the 2 placement of DHA, would side by side work best or one on top of the other ??? One more thing, since the field of view is roughly 135 degrees , would moving the front of the antenna a number of degrees to increase the field of view lose some of the reception of the antennas ??? Thanks Mr. Hop To It. for your educational videos and shearing of the knowledge. Peace v

    • @mrhoptoit7835
      @mrhoptoit7835  5 месяцев назад +1

      You could connect two of these antennas together. Side by side or one above the other would depend on your exact reception issue. I'd try each way. You can offset one element vs the other, but that would only work for very specific aiming issues. Normally its best to leave them in the same plane. Thanks, VF!

  • @victoryfirst2878

    Would using a reflector that is larger by a few extra inches in each four edges increase the reflective gain by a little bit MHTI ??? How about rolling the edges into a somewhat radius help also ?? Would placing two antennas side by side or one about the other increase the gain by a few numbers ??
    This is just an idea as I am not sure. The reflective part will be 304 stainless steel for corrosion resistance. An not sure what will happen using this material. Flea-bay had a special on a roll of mesh cloth. One more thing, would using a copper wire say a number 6 or 4 gauge help reception ?? I remember one of your videos showing that a 10 gauge wire did the best for reception of antennas Mr. Hop To It. One more thing, how good does this tenna receive low VHF signal. I live in the few places where low VHF still is used Sir.

    • @mrhoptoit7835
      @mrhoptoit7835  11 месяцев назад +1

      Hi VF. Enlarging the reflector will help gain, but it will narrow the reception focus. Using a radius edge could also do the same. Stacking antennas will allow you to collect signals from a wider swath, but how well it works depends on many factors. Using 304 stainless steel for a reflector should work. Increasing the wire to 6 or 4 gauge will increase gain potential, but in many cases, anything over 10 gauge isn't really cost effective for the minor gains you get.
      I cannot test for low VHF signals, as there are none transmitting in my vicinity, but this antenna probably would not work well for them. Try a dipole antenna tuned in length towards the channel you are trying to receive.
      Happy New Year to you, too VF!

      There are not many low VHF stations but some cities still have them. A yagi antenna with large elements are better. In the old days antennas that were folded dipole worked good on low VHF like channel 2 through 4 or five channel six was like an FM antenna I used my radio shack 175 mile antenna for that channel. Some say there is no such antenna 175 miles but mine over picked 175 and father. I picked up NYC from Orlando FL. And also stations in CO. Was the low end of the FM dial. I liked classical music and I did what I had to to pick up stations like near West Palm Beach from Lakeland FL. That's over 200 miles away.73

    Why are the rings spaced apart a certain distance ??? Yet the four hoops antenna so close together ??

    • @mrhoptoit7835
      @mrhoptoit7835  4 месяца назад +2

      The spacing was to intercept signals from a more vertical sample. You can also do it on the four hoop antenna, I just chose to keep the design simpler.

    Wrong copper is far better than steel , most commercial antennas are made of aluminum which is still better than steel. For stiffness use number 10 or number 8 solid copper. You can even make it stiffer by putting one end in the vise and the other end in a drill just a short turn will get rid of small kinks and stiffen the copper. There is a spray that will coat the copper wire to keep it from oxidizing. A little green won't hurt reception though. 73
