I just bought this antenna for $10 at a ham meeting in Reno last weekend (9/3/24). It was right in front of the Cameleon store! They had several boxes of 'stuff' for sale - cheap. DX Engineering was also set up at this meeting. I wasn't sure what I had with this antenna but you have helped explain it. Thank you.

I owe Eric a lot as he's the one that turned me in to your channel at Dayton a couple of years ago. Now I can't get enough Pota-wan Kenobi!

[Brighamdoc]

Awesome job!
So glad to see actual contacts not JUST SWR sweeps
But…
$180 for the antenna + $50 for the choke = $230
I hope it works well!

[dandypoint]

Obviously the antenna works! I would like to see the SWR curve as you move out of the bands as a sanity check. I always do that. The SWR should be very high somewhere. I get suspicious when the SWR is too flat. It usually means I have too much loss in my coax.

Looks like a great antenna. I was in a park Sunday 8/6 and got 20 contacts on 17 meters. The band is getting better. Love your videos.

TeamReplay for the win!
Great review. Thanks bud. Keep on rocking.
Party on Wayne!

[josephgomes]

another great show Mike. You always look like you're havin' fun, Joe, KC1MTM

[thed]

Yes to Chameleon antennas & yes to their choke. My first antenna was an EmcommII (with that choke), still in use. If gonna "buy" an antenna personally think CHA is a good move. Love yer vids buddy. Keep em comin'.

[kennethblackwell]

Excellent review. Great that you can integrate field just box opening.

[HammockRadio]

The LEFS is one of my new favorite antennas. They "recommend" the choke in the manual, but it should be "required" in order to get all of the bands they say it does without a tuner. After I got one, I had the same improved results as you.

[kareneighth]

Do you use a counterpoise when using the choke? If not, where is the “other half” of the antenna? Normally an EFHW uses the coax as the counterpoise.

[mikeh]

This is the addition I need for my POTA kit. Thanks, Mike! -KE0VIM

[josempantaleon]

Not bad Mike, given that it is capable on 40/20 and 30m I'm sure it will catch the attention of the SOTA folks that operate the MTR3B as well as their other multi-mode, multi-band radios. 🤘😎😼

[omnisteverino]

Nice and concise. Looks like a great piece of wire.

[daveNMXX]

Why would adding a common mode choke at the feedpoint allow a 40M efhw to resonate on 30M???

[johndeere]

Does anyone now what antenna analyzer that is I see it's a mfj but can't see model number thank you

[dbmusic]

I'm listening to you on my shortwave radio right now, lol

[CharlesSmith-dhgf]

east texas here looking to find you on the air waves

[DayAtTheBeach]

Hey Mike! Love your channel. Question -- since the antenna is a multiple of a half wave on nearly all important bands, the voltage and current, and therefore propagation characteristics will be the same at each end of the wire. That being the case... why do you run the 49:1 transformer all the way up in the tree as opposed to running the bare wire up there and having the transformer right on the ground, allowing you to fly less weight and use less coax? Should work the same regardless of which end you feed it from, yes?

[willian.direction]

Why don't they fit the "choke" straight into the transform on a piece of coax then just add a line socket type so239 then you wouldn't need all the adapters.
