80 meter Skyloop Antenna | Chameleon Antenna

The Chameleon Skyloop Antenna is a full wave, ham radio horizontal loop. It is big, efficient, and extremely quiet, and nearlyinvisible. If you've the space, this HF antenna is a weak signal dream!
Hello Operators.
Our choice of ham radio antenna, will make or break our stations performance. Today we take a look at the installation, benefits and performance of one of my new 80 meter horizontal loop antenna, the Chameleon Skyloop. The Skyloop (similar in design to a skywire antenna) is a full wavelength, horizontal loop antenna, resonant on 80 meters. It will be installed in a delta loop configuration, horizontally. Although designed for 80 meters, it is usable on frequencies up through 50mhz.
When compared for a vertical antenna, the first thing most operators notice, is the extremely low noise floor. If choosing between something like the DX Commander or other quarter wave HF antennas, the difference is amazing. If you have lots of noise at your QTH, choose a horizontal loop like the Chameleon Skyloop antenna for HF.
It doesn't matter if yours is a ham radio contest station, for ham radio emergency communications, or a portable ham radio station operating during ham radio field day. The Skyloop HF antenna will boost your stations capabilities in unimaginable ways. It is not a magic antenna, but it is extremely well designed and proven ham radio antenna system.

[@phildurall7466]

Julian ... you are spot on about the Skyloop. I have always lived in extremely compromised size lots. When I use to live in a condo in Aliso Viejo, in the late 80s, I lived on the second floor with a third floor loft and found a way to route a twinlead feeder that connected to a 20 meter rectangular loop I laid on the top of the roof which was at about 30 feet above ground. The HOA was clueless, since there was nothing to see. I experienced amazing results with it. I could load it up on 80 by tying both conductors of the twinlead together and using the loop as a capacitive hat. 40 - 10 were also possible feeding the twinlead thru the tuner. I was able to work all continents, and enjoyed the same low noise floor you noted. Keep the great content coming Sir! 73, KF6IF

[@kd5txo]

I used to enjoy an 80M full wave horizontal loop fed with 450 Ohm twinlead to a 4:1 balun into a Icom 703 QRP rig and was able to transmit/receive Japan from Midwest USA via greyline propagation almost every day with 10 watts (or less) SSB 17M band....the Japanese stations were using monoband Yagi antennas and we could ragchew both of us dialed down to sub-10W levels. They were impressed to hear this from a simple omnidirectional wire antenna setup.

[@davidc5027]

My Elmer uses a 'sky' loop, and has great performance as well. One of the reasons for the performance, he tells me, is because most interference is vertically polarized, so naturally a horizontal antenna won't pick most of that up. His noise floors are insanely low too, which is great for at least being able to copy some really weak signals. The advantages are you can work all the HF frequencies with 1 antenna, and the wire length itself does not have to be resonate. In fact the longer the wire is past 160 meters the better. Another advantage to using a horizontal loop is the stealth aspect because if you didn't know what you were looking at one would probably never guess it was an antenna, so great for neighborhoods locked down with a HOA. Don't think for a moment you might be limited to trees because loops can work in attics too. Really, I don't understand why these aren't more popular.

[@forextraderradioman]

Thank you for this video. Yes, I can confirm, such antenna (I know them as a Lazy-Delta-Loop antenna) are excellent HF allround antennas. 80m or, if possible, 160m circumference will make an excellent antenna which is resonant at every 3.5 (or 1.8) mHz. And the beauty, if mounted "lazy" (lying), that antenna performs superb at the lower bands for short-distances (NVIS and close to, because the high above the ground is 1/4 lambda or less) an if you go higher in the bands, the radiation pattern goes down, if you continue to 1/2 lambda or more above ground. So that ist THAT what we need, lower frequency, higher radiation pattern, and higher frequencies, lower patterns ;) I have had such antenna with 84m circumference in abt. 12m up in the air, feeded with ladder line and at a different location with koaxial cable and a 1 : 2 and also with a 1 : 4 balun. Worked both wonderful. vy73 from Hamburg/Germany, Dietmar, DL4HAO

[@BrianEsche]

As you noted, a wire loop cut for 80m (or even better - 160m) is a tremendously well-performing antenna on all the HF bands on its fundamental frequency and above. I first used a loop at Field Day about 10 years ago and was amazed at the gain and low noise. I've since tried to use wire antennas of various types but I always find the loop to be a significantly better performer.

[@OH8STN]

Thanks for this feedback. It's amazing how well these perform. Honestly it was difficult not to be skeptical when first learning about them. I imagine this is where the saying "get more wire in the air" came from. 73 Julian oh8stn

Great vid Julian. I have the room for the loop. Love the low visibility. I prefer to fly under the radar for many reasons. The neighbors are the least of my concerns.

I have had a diy version of this antenna for several years. It is the best antenna I have tried. Mine is only 24 ft hi and is in a square configuration. The antenna develops lobes of gain the higher in freq. you go. I even hooked up my 2 mtr handy and checked into local nets. I have had QSO's all over the world. My biggest problem is the supports I have and the high winds we have here in West Texas. 73 KG5YUO

Just watched your video and I can say I have had similar results with a home-brewed horizontal delta loop antenna I have set up in our birch trees here in interior Alaska. The noise floor is so low on 80 meters that when I turn the radio on, I often wonder if it cam down until I hear another station. I can connect with very distant winlink stations on 80, 40 and twenty meters quite easily and would highly recommend this type of antenna if room allows. I took down my dipole and gave it away...

I love full wave loops. If I had the space and vertical supports that's my ideal. At my QTH I'm running an 80m doublet fed with balanced line. It's only 10 meters high at the peak, and I have an odd looking triangle shape. In the shack, close by the radio, I have a transformer (4:1 current balun) in front of an auto tuner. Gives me 80-6m match, and was quieter than conventional dipoles, with far less loss due to my feedline choice.

[@OH8STN]

Outstanding. Haven't researched the doublet before. What are its main benefits? It's always good to see you here by the way.

[@dkane0026]

Great video as always. I have a sky loop set up in much the same shape as you put your loop in. My loop is not from Chameleon it is a homebrew that I built myself and is cut to 40m as I didn't have enough space to get enough wire up for 80m. That said it preforms great! I live in a neighborhood so there is plenty noise and I find that the I am able to get the noise floor down to s3 or less in most cases. Sadly I don't have any experience with any different type of hf antenna at my QTH as this is the first and only one I have installed but it seems to preform very well. I am able to work pretty much any band I want from 40m-50m using a tuner and have also used it on 80m with the tuner. The 40m loop on 80m seems to act more like an NVIS antenna, I am not sure why but that is my experience with it. Thanks for the videos and keep them coming love your content!

[@OH8STN]

Outstanding feedback. It is still amazing that we don't hear much about these horizontal loops. Best kept secret for sure. Perhaps the next one will be a 40 meter version for JS8Call.

Only thing you could do better would be feed it with balance feed line 4” open spaced to back of tuner or ant match. I would be curious if you could squeeze out a few more db but at a little harder installation. Nice tower 😉 I’m working with pines & maples at 80’ sadly only a 50’ cottonwood for the feed point so I’m in a hw dipole contemplating a loop or turnstile but going into HOA territory to put my elements may result in no wires going their way so may be better off trying a vertical from a boom out of the top of another maple I’m not using. Thank you for showing us mistakes and how to fix 😉

[@rogerp5816]

When you go back up to replace out the non resistant UV wire ties, and put the transformer box on a standoff can you open the box so we can see the quality of the build inside? That's my idea of an unboxing :) I've been considering putting up a sky loop so this was very timely and helpful.

[@KREllis-vr1ix]

Loops are great antennas. I'm running one now. Have setup many in the past including one for 160m. You don't need an expensive chameleon product to build one, however. A simple 1:1 current balun or 4:1 balun, paired with 14ga wire from the hardware store, are FAR cheaper than a prebuilt system. You don't even need to know how to solder. They're even cheaper if fed with ladder line.

[@carllavoie3804]

Well 4:1 and 1:1 UNUN aren't optimal for SKYLOOP when you want to reduce the looses at the minimum but still want to be able to push 600W CW or 1000W SSB. You're still going to need a waterproof enclosure because the antenna will spend YEARS at that location. The 14 gauge THHN (about $70 for 500' with heat capacity of up to 90°C will crack at sub zero temperature if you start to move it. This wire is made to be installed and not touched to move electrical power from one side to another) from the hardware store isn't suitable at all. First its WAY too heavy - you'll need EXCELLENT support to hold the whole thing up and thus without wind / snow / rain and ice factors! Then, the sleeve protecting the wire will start peeling a year or so later. Chameleon Antenna uses proprietary 16' Copper Clad KEVLAR PTFE (Teflon) (-70°C to 150°C) wire which is way lighted and way stronger. Yes - more expansive but designed EXACTLY to be a great wire for antenna making! So when you add it up: Wire ($70+) Water, shock and UV proof enclosure ($15) Stainless Steel and connectors hardware ($15) High power transformer made with PTFE solid wire ($20+) Labor and other ($20 to $30 at least if you value your time) You'll find out that you're already around at least $120 to $130+ and not even remotely close to a professionally made unit. Don't get me wrong, it's going to work but you'll be at about 2/3 of the cost of a professional unit without having professional building materials and professional manufacturing assembly with ZERO support! You really need to weight everything as its not as obvious as it might appear!

Thanks for the feedback. At this latitude, finding all the components, ordering, having them shipped here, putting it together, and longevity all add to the price of DIY.

Be sure to get a non conductive stand off on that soon. Those zippies will last a month. Use Dacron rope. I also run a delta config with my loop. You will find that apex up or fed here on the tower, you should have a lower take off angle. Even more so if you bring the other 2 ends low on the tree. 10’. They are truly great antennas. With longer coax runs, I prefer tru open wire ladder line. It really makes the higher bands shine. I’m not sure what “transformer” they use. Maybe a 4:1 or 6:1 balun. I’m fully able to hear people others in my area will not. Hence the sig to noise ratio. I’m somewhat confused why you run the rf gain down on the rig with this setup? Anyway, I know those arial lifts are not cheap here. About 350$ per day. But I guess it’s worth it. When you get bored, lower the tree legs of loop and see what happens. Will look for a follow on swr charts “pre tuner”. Tnx as always

I hope you're not using zip ties as a permanent install method. They just don't hold up when exposed to UV and heat/cold cycles for years at a time.

[@OH8STN]

I've already switched them out.👍

Hello Untill 2017 I had.a fullwave 80M loopantenna (83,0m long and grounded in the middle under the rooftiles and it was fed with 22,75m (78feet) of 450 Ohm Windowline which was connected to BALANCED LINE ON MFJ969/962D [4:1]and it perfomed well. Longest PSK31 with Michigan 8834 km and to the east Sverdlovsk by Caspian sea about 2250 km. About 4 years ago they made a overhaul to our roofs and just got to keep the feed Line. Entrys to roof is now looked with a padlock an freqvent inspections of "my roof" so I CAN NOT lay a new 80M (83,0m) loopantenna.[HOA] 73s de Gunnar sm6oer>>\

Is the transformer in the box a 1:1, 2:1, 4:1, 9:1, 49:1 or what?

Not 12M too... ?? lol. My favorite band !!

[@OH8STN]

I'm sure it works there, there was just no one on the band :-) 73 Julian oh8stn

[@user-ss6zt2mo1l]

@@OH8STN 12M is like 6. Sometimes it’s crazy busy and then other times nothing. Propagation is cool. I was so happy seeing that being installed. Waaay better idea doing it from the safety of the bucket. Looks as high as a Ferris wheel

How dou get you gui's in dark mode?

[@OH8STN]

On Windows, search screen settings "Turn high contrast mode on". The profile I use is called "high contrast 1". In JS8Call, WSJTX, JTDX, you'll need to set the color settings as you like. FLDigi is practically impossible to setup good colors in, so I stopped trying. Winlink has a custom color setting under a menu from msinbscreen. You czn chznge font, gordground colir, background color, and size. Other apps adapt to Windows color profile settings. Hope this helps 73 Julian oh8stn

@@OH8STN I use Linux and pi4b I have changed what I could. But I like yours. I run at least 2 rigs in the shack and it can get bright.

[@OH8STN]

Well linux and the raspberry pie are more difficult. Just like windows the apps I mentioned can be customized within the app settings. For PAT Winlink, I installed a plugin for chromium called High Contrsst. This allowed me to invert the colors.

[@BabylonLurker]

I would love to do this, but max height here would be about 7m. Anyone with experience of Skywires that low?

[@OH8STN]

I was reading about Sky wires and Sky Loops. that even 6-8 m height can be more effective than a dipole at the same height. If nothing else at least give it a try.

@@OH8STN Hahaha, yeah we've all been there. If somebody makes UV and weather resistant zip ties, I will buy them all. They're just so darn useful, and surprisingly strong!

[@gilbreathca]

Haha! @5:30 Does EVERYONE in your country have ladders permanently installed on their roofs? I can only imagine that's for snow mitigation?

[@OH8STN]

Every standalone, detached and row house needs them. They are for fire safety, and chimney cleaning.

The skyloop is the best antenna I have. It needs lots of space, but it can hear a pin drop on the other side of the planet on a bad day. 73 Julian oh8stn

[@Rickm505]

zip ties are eventually destroyed by UV light.

[@Philip-KA4KOE]

Get queasy just watching...can't deal with heights.

[@OH8STN]

Same problem at times. Just have to suck it up then focus on the job 🤣👍 73 Julian oh8stn

[@DD5LP]

Another comment that might be of interest on every multiple of the fundamental frequency the skyloop has gain in the direction away from the feedpoint. Of course in other directions it then has a small loss (the gain has to come from somewhere!).

[@AngelVillaG]

My 12m fiberglass mast and my dipole inverted V is better installed at temporary location. Sorry, it's my honest opinion! Better installation next time :-) HJ4AVG, 73

[@OH8STN]

This is not designed as a temporary antenna. Moreover the dipole has less gain and more noise than a horizontal loop. That's a fact, not an opinion :-)

[@vironpayne3405]

Black zip ties.

[@OH8STN]

Thanks I'll switch them out soon 🙏👍
