7 "No Tuner" Ham Radio Bands with One 63' Endfed Wire -- That's Not Possible! The LEFS8040 Does it!

[@Summicron1951]

Another great video and the more raw presentation did not detract. A well planned and informative video.

[@HOAHamRadio]

Thanks for the feedback. I second guess myself when I do things like this, but sometimes its nice to just go simple.

[@MrStanwyck]

I like Blooper Bob!!! LOL 😂. I’m glad to see this antenna is getting you access to bands you normally don’t get.. 73, Bill KC2KNA

[@HOAHamRadio]

That guy may show up again from time to time. Thanks for the view and comment.

[@yeahitsk]

I have the older 40-10 CHA LEFS and it has been my POTA workhorse. If I can get the transformer into a tree, that's what I prefer to use. It's taken a beating and keeps on ticking. Great for winter activations as the excellent band agility means you can just sit in the car with no need to get out for antenna adjustments.

[@bryantwalley]

I think most of us think about it the same way you do. 2 or less I take it as resonant and dont care if it technically fits the definition.

[@HOAHamRadio]

Sometimes I say stuff out loud that isn't technically correct, but its how we roll. Didn't think we were the only one.

[@Krispin291]

Always great videos! Love it! 73

[@HOAHamRadio]

Thanks for the positive feedback @Krispin291, always appreciated.

@@HOAHamRadio … and placed my first order from your site!! 👍

[@mrkopecky]

Blooper Bob is like me. That portamast keeps me thinking. I tried out the KJ6ER new champion yesterday, looks good too. But then blooper Bob does this. Thanks again. KZ4OY. 73/44

[@HOAHamRadio]

Ah, so I created a dilemma for you : ) Nice to have so many options.

[@kenmartin1211]

This Antenna gets good reports. I do not use one but am a fan of resonant antennas . The cost for this EFHW Antenna is a bit high but then again everything is these days. Best of luck getting it up permanent.... Thank You

[@HOAHamRadio]

If I'm successful with the perm set up, I'll be sure to share it with everyone.

[@kenmartin1211]

@@HOAHamRadio Thank You !

[@bendeleted9155]

My compliments to your drone pilot. Rock steady. 😉👍

[@HOAHamRadio]

A little secret, its me with my 360 cam : )

[@bendeleted9155]

Good to know. I just fired my drone pilot. 😂

[@stevesutton1930]

Great video.

[@kennethperew]

Can you run your antenna wire diagonally across your property? That would give you the longest length. I bought this antenna, it came in last week. I also bought the 49:1 UNUN from Chameleon in the weatherproof enclosure to be able to leave it outside. Haven't tried it yet, maybe this weekend.

[@robcarnaroli269]

I would love to see someone cut the wrap off and show what the magic is on this UNUN. Looking at another one they make they use 15 turns instead of 14.

[@goobercrow198]

Nice content sir. Curious, you mentioned 3 wspr transmitters, do you disconnect these from their antennas or have some disconnect switch while you’re transmitting on your hf rig?

[@GoAmateurRadio]

[@WD0OMHamRadio]

I was trying to figure out what you were holding and how the camera was following you! It was the tripod all along! The angle made everything but what was in your hand basically invisible. I thought for a moment it was a drone!

[@HOAHamRadio]

Its called a Insta360 camera, and it does crazy stuff. The selfie stick must disappears through the software I use to edit the video later.

[@WD0OMHamRadio]

@@HOAHamRadio Yeah, I guessed that might be the case -- there's actually just a little bit of distortion near you that seems to corroborate that idea.

[@willian.direction6740]

Try an elevated 80m 1/4 wave earth radial on your normal 40/10m EFHW I tune my parks 40/10 antenna on 80m with that set up. ft891 50w into a Z100 tuner. Seems to radiate pretty good to work any keen park chasers/hunters.

[@hermhalbach]

Hi Bob, I need 80 - 20 M bands for WA state EmComm from a small inter city lot (RFI high) or running portable. The best antenna for home and portable has been the CHA EmComm III Portable. I run mostly NVIS within a 40 to 300 mile, day and night, envelope and often work Asia to Europe depending on conditions on all open bands 160 - 6 M, with and without a tuner, all below 2:1 without except for 160 M which is still below 3:1. For $35 less, but 10 foot longer, you could be on 80 without that extra 130'. I would be interested, after seeing your numbers with a LEFS8010, how a well an EmComm III would be performing from your location as an inverted L(?). I don't know how to send you an image of today's swr sweep or I would. Thanks for all you do! 73 Herm, W7HRM

[@HOAHamRadio]

Hmmm. I'm gonna have to consider the EmComm III now....

[@johnsalisbury7664]

Great video. I am curious if you have looked at the matching unit to determine if it is in fact a 49:1. Could it be a 64:1, that would be interesting for conversation. Thanks so much.

[@dorvinion]

In the last video I was curious about it and whoever runs Chameleon's YT said it was a 49:1

[@BallJarSo]

I was definitely questioning that original claim, and I am intrigued. I had an LEFS for a while but I never saw SWRs like that. I wonder if the elevated feed point makes the difference.

[@HOAHamRadio]

Not sure about the elevated feed point, but I may find out in the next few weeks. I plan on trying to install this at my QTH permanently, and if I can pull it off, it will require the feed point to be low to ground. If I can pull it off, you'll see it here on the channel.

[@BallJarSo]

@ look forward to it. I bet the soil composition is in your favor too. Nothing but clay and shale up here.

[@HOAHamRadio]

@@BallJarSo Yep, I have an unfair advantage there for sure. Rarely do I have trouble getting good SWR with a vertical and a mediocre attempt at ground radials.

[@leestanphill1]

Are you using an antenna relay? What is the clicking/contact closure when you transmit?

[@HOAHamRadio]

Very astute of you. I use an MFJ SDR relay switch to protect my SDRPlay receiver during transmission. The large waterfall display you see behind me when I am making voice contracts comes from SDR Uno software. It is the MFJ relay that you are hearing clicking in the background.

[@leestanphill1]

@ that’s awesome. I’m using a DX commander, but as you know, verticals receive everything incredibly well, especially noise. I’m going to use a long wire on the ground for receive and the DX commander as my transmit, but I need to get an antenna relay set up. 73

[@npsarac]

Ok, rookie question, how does your camera do all that panning and zooming. It appears you aren’t running the camera remotely. Nick KJ5HSL

[@robcarnaroli269]

Looks like a 360 cam. You can pan tilt and zoom in post or even post in full 360 and then you can pan at home.

[@HOAHamRadio]

Yep, 360 camera; edit the video in post shoot and you can do all kinds of crazy stuff. It lets you be a 1 man production crew.

[@angelodepalma538]

Thanks for the video. But $225 + shipping for an EFHW ... yikes.

[@Ammed_KN6STX]

Great video Bob!!! The LEFS 8010 is my second-best antenna in the mass amounts of antennas I own. I sent you a Telegram question can you give it a look and give me your feedback, I value your opinion!!! Thank you, Bob. 73!!!

[@HOAHamRadio]

Now I'm thinking I want to find a way to install this permanently at my QTH. Would prefer the TDL but that gets some attention here in the HOA.

[@laszlokovacs8827]

Get out your box knife and lets see whats under that wrap.

[@billjobes1851]

Where is the right channel audio ? Left ear sound only. Next time maybe check before you post.

[@HOAHamRadio]

I'm not an AV guy so this stuff gets past me sometimes.

[@WD0OMHamRadio]

I know this experiment is specifically tunerless, but given that 80 was a mere 4:1, a radio with a built-in 3:1 like the FT-710 could probably make that work. It wouldn't be a GOOD 80m antenna at that point, but it would work.

[@HOAHamRadio]

Absolutely, a tuner could bring that 80 meter into a usable range.

[@thomashardy9994]

Yes. I was surprised the SWR was 4:1 on 80 meters.

[@WD0OMHamRadio]

Sorry to be Spammy McSpammypants. Some day I'll learn not to comment 'til the end of the video and just get it all in one. I'm not positive, but I think the "trick" is that the wire is actually a little short. An EFHW for 40-and-shorter should be closer to 66ft, I thought. Exactly why that makes the difference, I'm not quite smart enough to know, yet.
