    I found leaving the corners of my Delta Loop unsecured a good option !
    As when it gets windy, the telescoping masts I use, along with the wire, dance around like hula Girls, but when everything settles, they all seem to go back into proper position !
    But more importantly, being my first large wire antenna ( 270 ' ), and feeding it perhaps in an unorthodox method, ( Feeding it as an End Fed ), wire fed straight away into the house !
    One morning after a small rainy morning, I got up to see if Ten meters was open.
    I set down in a chair close to where the antenna wire entered the house, and holding a very tiny Belka receiver !
    If not familiar, I encourage you to look them up !
    Excellent Radio !
    They are encased in a metal housing !
    I attached the wire of the antenna to the radio via an adapter, and holding the radio in both hands, I began to tune the radio !
    This is where it gets a little foggy.
    As within literally seconds of being set down and beginning to tune, I don't know if I heard a distant clap of Thunder first, or felt the electrical shock in my hands, and into my wrists first ?
    But I received a significant electrical shock, that happened so quickly I had no time to react !
    Trying to gather my thoughts, my eyes went to the display on the receiver, only to find the display look like hieroglyphics !
    In a panic I quickly tried to shut the radio off !
    After several attempts, I began thinking of how I might open the radio, in an attempt to remove the rechargeable battery !
    As I'm hammering away at the power button, the display went blank !
    To which I breathed a sigh of relief !
    Sitting, still trying to gather my wits, I was wondering if the radio would turn on, and was already telling myself that the radio was likely toast, and I would likely have to purchase another !
    Whispering some quick prayers, I held the power button, and to my surprise, it came back on, and works fine !
    Testimony to the build of the Belka !
    Obviously a very dangerous lesson learned !
    I have begun collecting the necessary items, ground rod, lightning arrestor, and a length of coax, to get the wire outside, where it belongs !
    For those unaware, this was not a direct lighting strike, nor one even close by, as I remember hearing the clap of thunder somewhere off in the distance !
    And from the passing rain, the street in front of my house, had mostly dried up, with the rain having stopped likely a half an hour.
    Else I would have never thought about connecting to the antenna !
    But from that distant lighting strike, my antenna had voltage induced into it, at nearly the speed of light !
    Craziest thing I have ever experienced, to say the least !
    I feel very fortunate that the electricity didn't take a path thru my Heart, else I may not be typing this warning !
    Be way smarter than I, and be sure to properly protect yourself, and your property by using a lightning arrestor, and proper grounding !
    Keep the antenna lead outside , where it belongs !
    Lesson, all though terrifying, learned !
    Hope this keeps others from making the simple, but possibly fatal mistake I did !
    A real eye opener !!

    Oh my, I smell a new product line coming from DXC...called the "DeltaDXC" 😁. I like the 13/15/13 leg ratios, it just feels right for some reason. On 40m, bet this tunes towards 7.1MHz. Great build video, Callum. I can hardly wait for part 2 and of course the real world test of the DeltaDXC. 73 de VE3NAP.

    Hi Cal, looking forward to seeing this go up and the results. Mine works very well, much quieter than my end-fed. Good for G and Europe. Mine is fixed at the corners with just cable ties. So I can cut the ties and move the position of the balun for testing etc. That kevlar wire is really nice. 73

    I built an 80M delta loop in the 80s.
    Fed it originally with 300 ohm balanced line through a tuner..fed at the apex, hung vertically. It worked well.
    Put it up at my current QTH last year, fed with a 4/1 balun. Yes, it can be tuned and works from 80 thru 10 but the performance is not stellar on all bands. Alot depends on the radiation pattern as you move up in frequency.
    Mine is hung vertically, apex up, fed at the apex. Give horizontal polarization. Radiates well on 80 for regional contacts.

    I converted my long wire into a delta loop to try and reduce s9 plus qrm .. That certainly worked pleased to say.. I have 50m of wire in the air to a 9 to 1 balum. 4 to 1 I made was a failure. So the home made 9 to 1 unun works perfect. Should be a Balum Hardly needed the ATU .. Only 160m required atu... Found when i lived in Kent, the huge quad wire loop worked well just a few ft off the ground at the bottom of loop. So far results best i have had. Will stay with this. Also erected a vertical to compare. Mainly for the higher frequencies. . It works, that's the main thing. Being a retired electrician has provided me with all the tools and wire. One day we may work again.

    That a fun build to watch. Nice 4:1 Balun. Works for off set center fed dipoles as well. I had trouble tunning mine. Then I figured out I wound a 4:1 UNUN . My bad. switched that out and works and tuned fine for OSFD . The UNUN is mostly for End fed antenna. I made a mono band 20 meter veritable with 49:1 UNUN and ground radials . works super. My pole was not long enough so I fold back the top end like how the 40 meter is done on DX commander antenna. tuned great. under 1.7:1 the hole 20 meter band. This is cut 1/2 wave 20 meter band. 2 stack of FT 240-61 cores. 100 PF cap. #10 AEG mag wire on UNUN. takes KW just fine. using DX 10 wire. loop QRO loop on end. 73's

    Frigging lovely Job, Lord Cal. I love Delta Loop Antennas. My portable Version is 84m (275ft.) I have a 4:1 and a 2:1 Balun in my ToGo Bag. My Experiences with this Antenna fully satisfied my HAM Needs in low Height Setup somewhere at 22ft. lowest. My highest Point ever was at 48ft. from the Ground. That's quite a Job to get done for an one Man Army having this Thing up for just a few Hours playtime. I love the low RX Noise Level and even on 160m Band this Antenna was a Flamethrower. My British HAMily on 1933khz got knocked off their Shack Stools as I gentle knocked their Doors (RX) with just a 100W portable.

      oh and Cal, please do get this project sorted! I'm building a 4:1 choked balun for LOTG and delta loops.
      I know you plan to hoist the 'flat' part of the antenna up between two trees but for us no trees and one mast mortals 40m is a tough one. If you mount the apex on a mast the bottom leg of the wire should be 4m off the deck.
      So your mast has to be about 16m to achieve a true delta.
      Am thinking a flag pole style might be interesting with the pointy bit pointing away from the mast like this |>
      Would be fun to model!
      But 40m is a tough one for us mortals, hence the interest in you getting this one out of the shack and on air.

    I’m not trying to be clever, coz I’m not 🤪 However, from your previous vids… are you not going to be inducing the linear loading principle to the loop on the fold overs parts at the egg supports… 🧐 Can you use doubled doingy doingy loops at the eggs and the balun to support the delta? That should give you tension supports… maybe ?
