Going initially with 24 ft. circumference. The Vac Variable can easily fit inside the duct so makes a very nice package. Where are the inefficiencies in the Feed? What about a few turns around the duct and use Open Wire to a balanced tuner? How high of power can I do with 15KV?

    I used 4 inch diameter aluminum dryer vent tubing. Mine is 4 foot square with a square made of 3/4 inch copper water pipe for the sense or inner loop. I eventually found by trial and error I could get a good impedance when the inner or sense loop had a 7 foot circumference. (Note, it was very easy to build my design using dryer vent tubing and the elbows did not require being split. I suggest using it the next time if you don't mind $8 for each fitting and each two foot length of tubing. 3 inch dryer vent is also available and slightly cheaper) I am very, very happy with the antenna.

      So it’s a radio without knobs, what would they do to make it look better? The Maestro is a beautiful interface for the radio that has knobs and a screen and is a work of art.

      @@baldguyadventure I'm not talking about the box. The radio has a front panel, that's what I'm talking about. It is not pretty. It's clunky. It doesn't look designed, it looks like a bunch of parts from the junk box got thrown together. It has a lot of wasted space. Controls crammed together in one spot, spread all out in another. Compare it to an icom or especially yaesu front panel. Yaesu makes beautiful radios. It's the difference between a Lamborghini and a cybertruck. One is beautiful, the other looks like something a first grader would draw.

  • @michaelclueless
    @michaelclueless Рік тому

    Well, it’s a nice start for you. I noticed that you have a long stretch of wire acting as a partial feed line around the fence; those parallel strands with the resistor as a terminator will mostly cancel each other out, especially at longer wavelengths. I’d run the legs in different directions to avoid that. (One leg could run along the eaves.) I believe that explains the lack of superior performance over the attic loop, along with the proximity to the ground. Yeah, it’s hard to spot, but I don’t think it’s the right antenna configuration for you. I once ran an antenna in my attic, and my main problem was that the house’s electrical wiring was picking up too much of my signal, even at QRP levels. Lighting and appliances were affected, as well as broadcast television, and I felt it would have been cost- and labor-prohibitive to fix. I moved within a year. Welcome to amateur radio. I hope you have many happy adventures! 73 de KA4BGT

    • @cfjruth
      @cfjruth Рік тому

      Hi Michael! The wire along the fence is actually part of the antenna rather than being a feed line. Running the legs of the antenna in different directions as you suggest would make this antenna into a simple dipole. Those are fine antennas too, but not what I'm going for here. A dipole is good but only works on a single band. The BBTD or BBDL on the other hand gives up some efficiency in exchange for excellent broadbandedness (being able to work on every HF band). In order to do that, the antenna is designed around the two legs terminating at the resistor. I believe having most of the wire low to the ground is the main reason why the BBDL in my backyard didn't perform leaps and bounds ahead of the BBTD in my attic. If having parallel lengths of wire canceled each other out, then designs like the T2FD, folded dipoles or loops wouldn't work at all, yet they do. For more details, please check out the site where I got my design from: hflink.com/antenna RFI can certainly be more pronounced with attic antennas. Sorry to hear that you had issues with yours. In the three years I've had mine in my attic, I've had almost zero issues even at 100 watts. It causes no interference to our lights, computers, TV, etc. And none of our neighbors have complained either, including the one we share a wall with (being a townhouse). I'd love to be able to mount an antenna outdoors, high and in the clear, but moving isn't in the cards anytime soon. I'm glad for my attic antenna in the meantime. It has given me some 1,500 contacts, Worked All States, 67 DXCC entities and counting and many hours of enjoyment.

  • @arconeagain

    This is a video on optimising a small loop antenna, and you can't get any more optimised than for single frequency use. Can you please specify for me what fraction of a wavelength is most ideal for performance and efficiency?

    • @MrApolloTom
      @MrApolloTom 10 місяців тому

      Probably 1/5 to 1/4 wavelength. Any larger and it gets difficult to get the capacitance low enough.

  • @arconeagain
    @arconeagain Рік тому

    So for 27mhz single band use, what would the optimum circumference be? The antenna will be a circle.(When you say 4ft or 6ft, I'm not sure what you're referring to. Diameter maybe, area??) So would the optimum length/circumference be just below a quarter wavelength? Or do you want to keep it a fair bit less than that. I was thinking 2.5 metres for, say, 27.355mhz. Half inch Heliax will be used.
