Just pure gold! So many tips and pointers. My favorite is the counter-tensioning your RV mounted mast. I’ve thought that this method would be helpful for my home setup. It takes a lot of time to think through these variables. Thanks for this excellent video Kevin. 73
Had an 80M full wave loop for years. Hands down, my favorite wire antenna ever. Quiet, efficient and multiband. You might try feeding with twinlead with the 4:1 balun near the rig. Lighter, less cumbersome. 73, Marc, W4MPS
Thanks Marc, it sounds like a good setup to me. I have been thinking about a loop take take with me on camping trips. This antenna ended up at home and I really enjoy it at home now. Kevin
Balun Designs makes awesome stuff. Bob is just north of me, and is very nice. I use one of his baluns on a 40 meter delta loop that is ON my roof. Works unbelievably good with a tuner. Cool project...thanks for sharing! 73, Brett
It has excellent reception. Noise floor is a 1. I have been getting solid 59 reports. Compared to my efhw, the noise floor is 5-7 and signal reports of 55-57. I’m really happy with the results.
I have used an 80m loop horizontal for the last 15 years on 80 through 10 metres. Brilliant. Better than my EFHW, G5RV, vertical and half wave dipole. On 80m the feed impedance is 100 ohms but on the other bands it varies considerably. I use a 1:1 current choke from DX engineering and an auto ATU. My yagi takes care of 30m through 10m but sometimes I use the loop with almost similar results. I recommend using insulated multi strand wire and I just run it over branches and foliage in a rectangular format. Square format would be better but I can't manage that. I measured 80m of wire and put the current choke at the feed point with RG214 coax to the ATU. Cheers from OZ VK5LB
@K7SW ham radio I used thr 12awg green stranded wire from Home Depot and had it in my trees. Rental house in downtown Bellevue WA. S1/2 noise floor and talked to New Zealand with 50w during a lull in sun cycle. I hope to get it up and running here in Oklahoma soon.
Always funny how you Americans (and British) measure antenna length in lots of feet while you use metric meters to describe the wavelength it is intended for.
I too can confirm excellent results with my loop antenna also cut for 80 meters. My arrangement is an apex up delta loop with the feed point at a lower corner. I installed an arm on my 70ft tower with a marine grade pulley to hoist the apex. The corner feed has a 4:1 current balun which is fed from the shack by RG-213 coax. I'm also using 17 ga. electric fence wire for the antenna itself. It's very strong, does not kink and has lasted for years. Overall, if you have the room, the loop or delta loop is simple to assemble, lasts for years and gives outstanding results. Bill, W2ZKX
YES, a very good HF antenna. I have been using an 80m horizontal loop for a number of years. Mine started as NVIS at 10' it now is 10' to 30' and never was square. It was a triangle now more trapezoid. For me, the feed is 450 ohm ladderline to a 4:1 voltage balun and a 1:1 common mode choke (effectively your 4:1 current balun). I have worked ZL and VK from the east coast USA on digital modes - 80m, last month (july 2022). 73, steve WB3LGC
Steve, I must say, this is a fun antenna and I can already see how well it works. Other than the amount of space it takes up, I can understand why you have had your antenna up for so long and why you enjoy it. 73 Kevin
FW horizontal loops are great antennas. They are simple, cheap and work extremely well. A very quiet antenna. The only downside is that you need lots of room. Circle is perfect, square almost as good but whatever shape you can get the antenna up in, it will work. I have tried coax and ladder line with different baluns. Best was q-section and coax. I've built these for 80 60 and 40m. 73 Ed.
Thanks for posting this great video. I've used a 160M Loop antenna up 80 ft. Had some tall pine trees to work with. With only 100W during contests I was able to cut thru the pile-ups. Love using a Loop antenna.
Sometimes it can take you 1 or more Hours to have your Antenna System up and ready to plug 'n' play. Your Setup looks really nice and I know this is going to wrok out fine. Happy Sunday Evening & 73 de YFUG 💯👍
Great video, I put up a 80m loop with 266'ish of wire and it has become my primary antenna at home. Would be interesting to use at a park, but I don't think we got any as wide open as that in Mississippi :)
Thanks Joe, yes it is an interesting antenna for sure. I could see how this would be fun for a field day antenna as well. I may have try this again out camping with larger trees. Just for fun😉
@@hamradiowithkevin you mentioned larger trees, I forgot to say my loop is at 25ft at feed point and about 20ft the rest of the way around. My soil is mostly clay which is why I think it works so well at a relatively low height for the bands.
I thought I could’ve used bobs 4116 4:1. He says not so. I’m dying to get 80m loop up with no trees in the back yard. Hehe. My 40m delta works very well.
I would really appreciate being able to see a drawing on a piece of paper of the antenna directions and shape ?? But I understood 90 % of everything. One question I have is what if all you had on hand was a 1:1 balun , would that work well also ? Great video . Hope to hear back from you soon 73 KK4ISW
I'm a huge fan of the full wave loop. I have a 160 meter 6-sided loop at my home QTH and your observations are correct. It hears everything!! 😃 I applaud your effort, but for a POTA activation the setup logistics would seem daunting if not impossible. KZ9V
Was the area within the loop clear ground or were there trees? I have been thinking about how to put up a loop at my house and I don’t think I could do it and have the area within the loop clear. Curious to know what the vegetation was like for your experiment.
For this setup, the area WAS clear inside the antenna area. Since then, I have put the antenna up at my QTH which is directly over my rook and some parts of the antenna get into the trees one one side. I still hear signals really well and make some good contacts. It is worth giving it a try I think. 73 Kevin
Most of my 160 meter (and harmonics) loop impedences are measuring between 100 and 150 ohms, so I went with a coax fed 2:1 current balun on my loop antenna. KZ9V

Bob is 100 percent solid on product and customer service.
I just bought a throw line… a real one. I’ve used my crude compromised wanna-be throw line for 20 years… oh, how I wish I’d have bought this sooner!
I totally agree, next i will be ordering the folding storage box. It has to be better than a bucket😉

Great presentation. Didn’t have to speed up, and the “um/uhh” meter didn’t get a single hit
I’m in the middle of doing a 160m loop. For right now I am going to test in a wide open field, so it should go up easy.
Very cool
@@hamradiowithkevin I’ll let you know in a couple days how it worked out

with a nice setup like that, it is hard to go with anything less, nice work
@@hamradiowithkevin thank you! I tried to post a pic on QRZ but how do you get the whole thing in frame. Hehehehe. KD9ZSP

That sounds super fun. 👌

Dang, thanks a monster antenna! Nice tip about checking the length 👍
Thanks Ape, i appreciate it, good to see you.
How much work would you put into getting an HF antenna up at a camp site ?
I have not found that limit yet and i think it drives my wife crazy

Thank you very much!
Great video and thank you for the contact when I was out doing POTA! Conditions were good but that antenna was still adding something extra.

Resonate at 3.3mhz 280 feet a tad long. 267 would be 3.5 the very boat. Oh as I listened you trimmed 😊

Yes Jack, I am convinced that it is a great antenna to use! Can not wait for spring to get this portable antenna up in the hills.
I use a fishing pole to cast over trees, then attach paranoid and reel it up over the tree top.
Tom, yes that is a great idea and makes it easy to deploy an antenna. 73

Google an 80 Meter horizontal loop for the dimensions. You will need a 9:1 balun. Check the description for the parts. 73

That is a slick setup! What park is this?
POTA Video from multiple locations at this park should be ready by next weekend. K-4397 is the entity.

Maybe I missed it but did you have a counterpoise or ground attached to the balun?
this was one BIG loop, and the ends of the wire connected to the Balun. One on each side.
Have you tried 2.5:1 balun ?
Robbie, I have not. I suspect the impedance match would be off because of the good match that i currently have with the 4:1 balun.
Most of my 160 meter (and harmonics) loop impedences are measuring between 100 and 150 ohms, so I went with a coax fed 2:1 current balun on my loop antenna.

How about open that loop to just the dipole and get three DB extra
Actually, I have been working on something just like that... Thanks for making the suggestion 👍
