In 20 minutes, this antenna became a "go to" for ME | K7SW ham radio 

What multi band HF antenna do you use ?

I subscribed for 1 reason your voice and presentation is so much easier to listen to than most hams on RU-vid.. pleasant voice and good teacher ..

Fantastic. Thanks for the review!

Great review, thanks for the practical application, 73

Thanks Kevin I enjoy your videos, nice job.

I just got a K9SAB end fed random wire. Working very well.

Wow, what an excellent video. Very helpful. Thank you for all the hard work.

What a great video! I have been enjoying your videos more and more. I think it's the way you present and the calming voice, but I understand and retain more from your videos. Thank you for all you do for our hobby and the community.

Excellent video. Appreciate the details especially for someone like me learning about different antenna configurations. Many thanks.

Kevin, fantastic video. Thanks for all the work you put in to review this antenna. It won’t be long and you’ll have 100K subs!

Great video! You explain everything with detail but in an easy to understand way. This is the first video I have watched that you have put out and I am looking forward to watching and learning from your other videos.

Excellent production, kept it moving while being very thorough, made for an enjoyable, worthwhile, and data rich presentation. Learned a lot about that antenna, performance, and deployment. Great job! Also a nice demonstration of that AA-230. Thank You

Very nice review. Thank you. Good work as always.

Thank you for the detailed assessment of this antenna .. well done.

Thanks for the review, very informative. Shared with two others.

Excellent Video! Very well done. I can't believe you only have 2K subs. Thanks for sharing.

thanks very much for a really good post.

New to ham and so much to learn Thanks!

Thank you sir. This is great information.

Great video and information too !

Thank you for this. You really helped me decide to purchase this. I’ve been looking at this trying to make up my mind as to whether or not this was a fit for me. 73, KY4BCD

Thanks for the review! I really like the build quality of Chameleon.....and I have this antenna. I started out using it for field day this summer thinking I would swap it our later.....it worked so good I just used it the whole weekend while camping.

Im just excited about your idea to mark my coax... 😂 Thank you for taking the time to share this product and its different configurations... I really enjoy your content. 73

Quick suggestion for others using this antenna. I have one.....and when I raid it up I have the coax looped through the hanger so the weight of the 25' of coax is not straining on the antenna's feed point.

With the previous version, 10/40, from my QTH in Georgia, I've reached Idaho using 20 watts and the antenna at only 20' about the ground. I can't wait to get this version. Thanks for this video

Thanks for the video. Your efforts are appreciated! Liked and subscribed

Nice demonstration. I recommend this video to my new ham friends and then show them how to make one. Chameleon makes it all if you don’t want to build your own and for some of us that is good. Anything that gets you on the bands is good. The 49:1 transformer is the key and how one makes it is important. Understanding how and why it works is even more important. Thanks for the video. Dave K8WPE since 1960.

I use the Chameleon Hybrid mini with 73' or 130' wire. works great, doesn't need a tuner either!

I have a 80-6 meter line I want to get up, I live in an apartment complex so my installation is going to be more creative here but these were some good ideas for sure. I liked your antenna analyzer as well just wish they didn't cost so much.

Loved this style of video. New ham as of January 2020. Good video as always. I enjoyed your solar discussion with Ape and the Coffee and Ham Radio guys from Oct 1. All the best, 73 de KI5HXM

Smiling! Looks and sounds good, thanks for the good review. DAt home I use an 80/40 center feed dipole at about 55 feet center and 30 or so at the ends. For the most part 80 meter loop 30 ft feed point and 15 to 20 at the 3 corners, is my go-to. Don't do a lot of portable operation but have been thinking about it. Load up the Jeep Wrangler and go play.

Love hearing the OMISS nets.

Great video and review. Thanks. Subscribed. WG7D

I really appreciate you for taking time to hook up this video about hooking up this type of antenna it was very very useful im Tyrone from Baltimore city, I'm mostly on the cb radio bands but I'm getting ready to get my novice license, hope to q,so with you really soon, until then stay safe you and the family,.Grave Digger, 660 state of Maryland,.10.6#10.7,.so long..........

Thanks for the video.

Very helpful

You have a very good "radio voice." Perfect for this.

Hey Kevin, terrific video! I have two end fed antennas, one 80-6 meters which didn't state it was a no tuner needed, but at home it had good SWR readings on all bands. I also have another 80-6 meters which states no tuner needed, which is still in the package for camping, I think is longer than the other one. I'll see how it performs once I get to go camping again. I currently have two QRP transceivers and am looking either for an amplifier or a higher output radio. Thanks for the videos de N7MRF.

I love these antenna videos, I may have to get a real rig to supplement my 40M Tinned Tuna transmitter, LOL. 73, Dave, KU9L

Great video and very thorough. I have the 10-40 version and use it all the time. I am sad to see that Chameleon still hasn't changed the end ring and rounded them off after they've gotten a lot of feedback on them. The squared off edges can tend to kink the loop over time, especially adding that extra length. Anyway, keep up the great vids. 73

Great video and good work Kevin, just bought this antenna few weeks ago and starting to enjoy their benefits! You inspired me to try different feed point altitude and see swr results, thanks!! Just dont understand how many guys worries about Chamaleon prices! we are in a free world and it seems to be many good alternatives al lower prices so why bother??

For the reason I have not in off time a G5RV at 15 ft from ground and 2x20m long with twin lead of around 10m long + air Balun 4/1 ... I'm quite happy with it.. of course all homemade 😊

Great interesting review, I’m EFHW fan and they are amazingly cheap to make and easy to deploy. I like many have experimented with optimum height off the ground for the matching unit. You are very thorough in your assessment and show them how most would deploy them in the real world. Band conditions currently are so bad it takes a lot of patience. Thanks for your effort and the time these things take to produce 👍🏻😃 73 Mike

Great video, Very well done and very informative.. I'm looking to put up a good multiband antenna so this maybe something I'm interested in. Thanks for sharing.. Have subscribed as the way you do your videos is great. 73 ZL1MY

There was Russian women who laid the long wire on the ground with great contacts. Yours got better the closer you got to the ground. You should test it on the ground just to see the results you get with this antenna. It was amazing the contacts she made.

That is nice. I like building transistor radios and crystal sets and I believe this would work great. At the moment I'm using an telephone line and I get a lot of echo.

thanks seeing the antenna tests and set up has finally persuaded me to pull the trigger and get it love the vids layout and you explain it very well and so i have ordered mine will look forward to any more videos like this in the future thanks Phil 2E0FJQ in the UK

Since up a 40 meter E F H W at 30 ft I am really impressed and worked japan QRP from Colorado Sppprings using a 817. I have built 4 more and set up for qrp thru full legal limit. 73

Thanks for the vid! I've been using a Buddipole for HF but find it tedious to tune the coils, and I have little need (so far) for a free-standing antenna system. You're really selling me on the idea of using a throw line and wire antenna.

thanks bro

Like your videos,… watching from Kentucky “ The Bluegrass State “ … 73’s

Nice review, very comprehensive. I have the Chameleon LEFS 40-10 model and it is one of my go-to antennas. I've been using it for over a year and it holds up well to the abuse out in the field.

Nice work. The FT-857 tends to sound far noisier than band conditions actually are, as you've noticed. It helps to use their DNR or even just a speaker or headset that attenuates high end a bit. The internal speaker just isn't large enough to provide good low end audio. But it works. It just ends up being fatiguing to listen to for many hours. The choke generally works out better at the rig end.

The KX2has a great sounding RX Audio. And in Combination with this Antenna I would say it's performing excellent.

I have this antenna and with the feed point at about 25’ I found on 75/80 it was resonant way down in the CW portion of the band 3.5 and over 3:1 near 4.0 MHz. The 4010 from them works great and is my go to antenna. As far as the choke, I found it works better at the radio end for keeping RFI out of my Hiel headset, especially on 20m.

I love this video! :)

I use EFHW antennas quite a bit. One suggestion for you. an EFHW uses the coax shield as counterpoise. By placing the choke as close to the unun as you did you eliminate that possibility. I wonder what using something like 25 feet of RG8X then installing the choke then the feedline to your radio would yield.

Well, I would call that a comprehensive antenna review. You put a lot of work into that review, didn't you? I like that you don't do a lot of random gabbing, just the facts, and there were a lot of facts. Well done, sir. 73. Steve N7SR

When I was living up in Silver City, I used a Wrist Rocket launching a lead sinker attached to a 6 lb line to get my long wire up.

real world testing is far more valuable than calculated data - nice video

Nice video. One test is worth a thousand expert opinions. I appreciate you sharing what you learned from this experiment. N4DPH

The ground under the long wire antenna is important too....even if you have no grounding rod. Wet ground if you can. My swamp area under a 400 foot LW helps on all bands- KC1CCG

I am glad you finally used higher power. It makes a big difference. QRP levels are fun but having 50 or more watts really makes a difference unless you are using FT8. With the bigger lighter batteries 50 watts is easy now. K8WPE

great video. Subscribed.

Awesome video! Thank you. I just found your channel yesterday, so please forgive me. What mast and mount do you have on your camper? That is something that I am really looking forward to setting up for myself

Kevin! You always do an excellent presentation, and your videos are well done. Chameleon needs to give you a discount code to offer to your subscribers ( ;-) lol ). Look forward to seein' you out there. 73 de Bill

Thanks Kevin. First time I saw your channel - Subbed. I'm looking to buy or make one of these 63 ft long antennas (all the space I have) as my first HF antenna. Having a hard time finding steel antenna wire, though. International shipping from American vendors to Japan is ridiculously high these days. Can you tell me who sells the stuff in bulk? Also, I saw the current choke - do you also use a balun? Thanks!

Subbed. Your voice is awesome, Morgan Freeman: watch out!

Vy good presentation. English is not my native language, but you have a perfect voice and are easy to understand - even for me. The video quality is amazing, too. Keep on the good job. Vy 73, Jürgen Dh0pag

Thanks for getting on the job rather than having a life history you hear so much!

I have a 9 to 1 unun I bought off e-bay, 117 feet of wire, something, and at 19 feet in a sloper, I get less then 2 swr on all bands over 80 meters, I love it cost less then $20 , I also have a chameleon cha mpas 2.0 also run a tuner, I think you have a hell of a reflector with all that wet grass under your wire.

11:02 curious where is "this location", Utah? Any nearby lakes/water? If so, you don't necessarily need to "run to the hills" for better signal. Water makes a GREAT reflector for signal bounce and also means the soil is likely more damp for better ground effect too. If only the SW had more of this "water" stuff?! 🤔 Something kinda interesting about EFHW's and dipoles is they can be somewhat directional for TX RX, having a hair more sensitivity and TX power lobes out at 90‍° to either side of the wire element. Another config that effects your signal take off angle is using a sloped ^ inverted V shape. Tie your suspension throw line about 15-'20' in from the end of your 40m (66') element wire and hoist from there, so that 15'-20' hangs straight down. Then with the radio out on the "free end" it lets you pivot around that vertical hanging end at least a good 90‍°-180‍° to "aim" your signal. Helps to have a small backpack ETC to hold the battery and free your hands up to operate the radio too. Looking at an azimuth map also helps get your bearings where to aim. To hit Europe from say CA, UT area you'd set up pointed 90° perpendicular towards say NY or the middle of Canada, as the crow flies not directly East.

Good video, well done. Just a thought though...the CMC choke needs to be at the radio end of the coax and not at the feed point. EFHW antennas use the COAX shield as part of the antenna. Having the choke at the feed point doesn't do anything...and CMC currents can get down into the radio.

I have no clue, but it was fun to watch you be passionate 🍸

Pretty impressive. With the 80 meter wire added, you should have checked 17 and 30 meters. Nice setup. Barry, KU3X

FYI, Batteries drain out on the ground! A board or piece of plywood is what my dad always used to keep them isolated. And thank you for your excellent video content.

I have seen a demonstration where a longwire laid across the ground can power a sequence of LEDs from RF coming from a local AM broadcast antenna and a gap attached to a metal fence post produced a spark.

I have a BIRD Termiline I don't need a antenna tuner for either... We need to have some real life shootouts! Thank you very much for the video and the time that you put into it!

The other benefit of having a slightly low wire antenna is that it becomes more omni-directional .... especially if you do an inverted vee.

This is very informative and well done. RU-vid could take some notes from how you present.

Great video. I like how you presented the setup and showcased the antenna. Too bad you didn't try CW, the RBN can orovide some data on signal strength to various locations. Also, did you test 30m by chance? I would think it could work when configured for 80m.

If you're a CW operator you might want that 80 meter extension to be somewhat longer. The SWR down in your part of the 80 meter band is rather high to use without a tuner. But Mark Herman's results were different, with the 80 meter resonance down lower, so YMMV.

I got the 40-10m version. Tried it out on my IC-7300 at 100w with the tuner turned off, no tuner needed for 40, 20, 15 and 10m. 17 and 12m needs to be tuned. Chameleon makes great antennas. They are a bit pricey, but the work great for portable operations and at the home QTH. If you see them on sale at their website, that would be a great time to buy one. On a side note, I do not use the inline RF Choke made by Chameleon. I've heard of some people having an impedance mismatch with them. On my portable operations coax (RG58), I use a mix 43 torid about four to five feet from the feed point. I haven't noticed any RFI using the mix 43 torid or SWR issues. 73, W4ISB Mike in Tennessee.

Very good video! I noticed your rig was back lit. I am starting to go blind and have to use a flashlight with my FT 710. I think your radio would benefit me and my sight. Thanks WB9VVH

A bowline would be a better knot to make the loop in the tethering rope. Easier to untie after being under strain fr a long time.

Thanks for this detailed video! A question re the choke: Isn't chameleon selling a 50' cable with choke where the choke is supposed to be close to the radio and not the feedpoint? Doesn't the antenna need the coax shield as a counterpoise which of course isn't possible anymore if a choke at feedpoint is used. Would be a good experiment to set up like this and measure again?! 73s de Leo DL2COM

I have ZERO TREES. I do verticals. Wish I had supports. Cool Antenna.

Using a 33 ft coax at the feedpoint, then the choke (and additional, needed coax) might improve the setup.

Very nice presentation, excellent descriptions! I have an OCF 160-6 Meter dipole that I am trying correct SWR. My 4:1 Balun is at 33%/77% point, 40 feet above ground, short end is about 20 feet AG, the long end is about 27 feet AG. Readings taken at coax at base of OCF point with AA-54 are rather strange, 160 meter at 2.0 Mhz is 1.8, but 20 meters is in 6.5 to 7.5 SWR, WHAT? I am going to try raising the ends higher, and also adding some length to antenna, and also may try to adjust the OCF point from 33% to 20/80 point as some operators have tried successfully. Thoughts?

What is the 857D covered in? With all this work have you thought about getting on Patreon? Thanks for your honest review, appreciate all your videos. Thanks

It would have been interesting to see some WSPR stats for that setup.

thanks for the video and channel! i ordered an 8010 from cha, along with the inline choke. quick question. knowing what you know now, where is the best place to put the inline choke? as the feed line goes into the radio or up high at the antenna like shown? thanks again.

Anything Chameleon is great. My 60’ Emcomm II from 5’ on fence to 30’ up in a tree works wonders for me across all bands (6-160m). Simplest and least expensive quality option in my opinion.

That's exactly what I'm aiming for: Reaching Oceania from the Great Basin. There is room in the yard for a 130' long antenna. But the tallest tree is only 40' high. Stable branches are barely 30' high. Wish there were a way to get a horizontal antenna higher. Perhaps the antenna line needs to be lighter - light enough to float on top of the canopy. Is this a thing?

It would be very interesting to know what is in the feeder point board. I suspect there may be a resistor across the feeder to flatten the swr?

I'am looking for a kind of antenna like this for my PL660 tecsun. but I don't know. what can be good. the antenna they sell with the radio is not powerfull.

Is there one for UHF? Have friends looking for some. Great video!

What do you have at the top of the mast on the travel trailer…. I need this!

Does it matter if the feedooint is elevated or if the end is elevated? I use my endfeds with the feedpoint closer to the ground (1-2 feet) and I'm wondering if I'm missing out

if the people around you do not understand what your doing , taking the low road, other hams will reap the benefits, take that t shirt cannon out and TELL the folks what is happening, change their programing
