Hi Rick I do love 80 metres, I'm just buying the field next to my home, it's some 6 acres but only a cupule of big trees around the edges. I hope to have some fun building some big loops and long wires. Making and testing antennas is always good fun.All the best . . . . Andy
Hey Andy, Dave is having a blast with the new 80 meters delta loop antenna. He also has a dipole 80 meter antenna so I am sure he has been doing a lot of A-B testing. Glad to hear you bought some land next your home, sounds like a great place for an antenna farm. Should make some interesting videos. Best regards Rick.
My 80 meter loop is by far my all time favorite wire antenna. I feed mine with 450 ohm twin lead with a 4:1 balun close to my transceiver with just a short run of coax. Loads on every band 80 through 6 and I've had fantastic results with it over the years. Instead of putting the balun at the loop feed point, try my arrangement. I think you'll be a lot happier with the results.
Loops are great antennas! My most effective arrangement has been a full sized vertical square pulled up into the big pines in back of my house. Fed at the middle bottom it acts like two dipoles in broadside. I use a 4:1 balun and it works on 80, 40 and 20; the even bands.
Beautiful all you need is the real estate you can put any antenna if you want I think it's awesome thanks for sharing this video Delta loops are one of my favorite antennas 💕
Great video. I'm thinking about putting one up before winter descends upon us. Now, modeling this with software, I get a LOT more low-angle gain by feeding it 1/4 wavelength from the " corner". And the SWR is about 200 ohm's and a 4:1 current balun gives a good match. Feeding it on a "corner" gives me a cloud warmer. Feeding it 1/4 wavelength from the corner gives me a radiation pattern similar to a vertical.
I have built countless loops for 75 and 80 meters make it a mono bander get rid of the balun and use a section of 75 ohm cable for a matching stub you will easily get a 1 to 1 match just by trimming the antenna or adding a little. If you want it to tune to any band using a tuner use a 4 to 1 current balun feed it with ladder line and trim the antenna to get the best match possible for the length the loop was cut for 3 to 1 or better. Usually 40 meters dont work to well on it but the rest work great.
I did exactly the same - 80m full wave horizontal triangle loop up 22m. Pneumatic launcher - CSV 17, #12 copperweld, no balun, 450 Ohm window line straight to the side of the KX3. With 10w I had 5-9 across 3 provinces on 80m SSB. Super antenna. Oh also used plastic covered clothesline wire for over the tree limbs - strong and slippery. 73!
Greetings from Leduc Alberta. Hope you’re still having lots of fun with your radio. Me I’m just beginning to school up for the exam. At 67 brain 🧠 ain’t what it was. 😂
@@ve6kk Thank you Sir for the reply and the encouragement. It may be a while but I will give you a shout out once I’m rigged out. God bless you and 73.
From my experience on 40 m the feed impedance at the top of the apex is 100 ohms I have not tried 1/4 wave of 75 ohm coax stub in to 50 ohm coax but according to what I read it should do the trick.
I made one for 30m and one for 60m. They worked great until the solid center conductor of the 75ohm 1/4 wave matching section broke, i need to find some other 75ohm coax or use a 4:1 balun.
HI from Dambuster 4 to 1 balun is 200 ohms to 50 ohms unless it is 200 ohms at the feed point you will have a mismatch. I have used open wire feeder on my 40 METER delta loop feed back to the shack to a home brew balanced tuner that way you have a multi band aerial. The impedance of the delta loop depends where its fed.

How much meter use 450ohm ladder line your 80m loop antenna?
I love Sid station beautiful the icom 7300 nice radio really nice shack I love to set up I love the land man you can have a blast kudos 👍👍👍👍💕❤️
Dave has been having a blast with his antenna farm, for many years. Thanks.

Glad the antenna is working well for you. Also thanks for the information.
I like his window sill antenna patch box, thats brilliant. I guess even with a real "Radio Shack" you still need a few more ways in and out.
Thank you.
Love the timber shack
Thanks
This is an excellent video, very informative !
Thank you, and your welcome.

Pretty cool, I hope it's doing well for you.
Thanks
I've been thinking of making one of these for my backyard. Thanks for the video! Hope to catch Dave in the waterfall! Looks like he runs FT8.
Thanks.
The more area inside that loop, the better it performs.
They work great.
What ballon did you use to feed that loop with 50 ohm coax
2 to 1
From my experience on 40 m the feed impedance at the top of the apex is 100 ohms I have not tried 1/4 wave of 75 ohm coax stub in to 50 ohm coax but according to what I read it should do the trick.
Can you show us exactly how you ran this in the trees to the feed point ? How far off the ground each “ element” is ? 73

Can you tell me If he Size of the loop to 80 MTS ?
Thank you
