A COLLECTION OF MURA SWR/ANTENNA TUNER METERS VINTAGE NEW OLD STOCK. ———— VERY RARE ————-
Video Rating: 0 / 5

The making of my single element Delta Loop antenna. Designed for 11m but can be used on 10 which is what I built it for originally but it works on 20m and even down to 80m although obviously a good antenna tuner is required. Ideal for short spaces. I was going to build this for 20m but the length of the rods would have made it dearer than I wanted to pay. This project was to come in under budget at £25.

    It depends completely on conditions and what the other person is using. Excellent for talking to local’ish stations with beams but not so good if they are using verticals. Depending on how the skip distorts the incoming/outgoing DX signal either can be better at times rather than the other one. In an ideal situation you would have one of each with a switcher box so you can change antennas instantly so you can chose the best antenna to use depending on conditions. Most DX I use the Delta

    Thank you for that, but I must say this one was actually meant to be educational :o)

    Excellent video. I use a horizontal 40m & 34m to cover most bands. I found a bit too much noise on a vertical loop. Similar to the Chris M0DOL portable delta loop, but have you tried the feed, or 4:1 balun about 1/3 the way up one side ? Supposed to give you more directivity away from the feedpoint/balun ? I tried a horizontal rotatable 10m loop, but with no real directivity. Thanks for the video, all the best M6APJ.

    Be a good idea to ‘whip; the ends of your poles with some twine, then coat with epoxy buddy. Their not made to stand much strain like that at the joint, so a 1/2″ of cord and a wipe of Araldite to seal it would pay off in longer life.

    C’mon the TunderBurds!

    Great video thanks. I see the stub mast is quite long from the rotator. Does this cause any problems with wind loding etc? Has the antenna faired well in the recent storms?

    if you look at the video again you will see a collar a foot or so above the rotator itself. That keeps the pole to the antenna straight and takes a lot of strain off the rotator itself. The recent winds here in Skegness have had no adverse effect at all so it is surviving quite well. Thanks for your question. Regards,
    Graham
