How to cut and tune EFHW antenna for 10 - 40
HTML-код
- Опубликовано: 27 сен 2024
- I show you how to make an End Feed Half Wave (EFHW) on bands 10 - 40. I will go over cutting and tuning the antenna for each wave. Then we will put the antenna to the test.

Excellent idea using the tent stake to secure the wire and tape measure, I will use that the next time I cut wire!!
Excellent! that long tape measure was amazing. i will be using it later for the DX commander build
You can fold over the extra wire and as long as they are parallel your tune is good. Great video to include the links instead of robbing power with a "tuner" that tunes nothing but instead matches the impedance to send reflect into components in the the device as lack of efficiency. Great work indeed!
Thank you so much. Its also at of pure laziness, not running a 40 meter antenna to just play on 20
Hi Tank. I think this might be the first one of your videos I've come across. I'm planning on putting together a linked EFHW for a portable kit to use during the upcoming Summer here in VK3, and you've helped with some great ideas on building it. Thank you, Sir.
I am glad it helped and thank you for swing by the channel
Great, simple antenna, nice job! Someday all of us Texas stations need to setup and do an NVIS net with every Ytuber running live simultaneously!
now thats an idea. but some of us are still too close for NVIS
@@TankRadio That's what ground wave is for. 🤣
About dang time...... great vid Frank
Come on, you know Frank's gonna build an antenna before Jason.
Thank You, this video was pushed back in the queue due to Dayton and then Field day events. COME ON, i was waering a hoodie
Thank you! Just the video I needed.
Glad it was helpful!
I really love this video! I'm going to try a build of this antenna! Great work Tank! Quack Quack
Thank you, if you need help let me know. Go forth and Quacker my Duck Commander
Fantastic video! It is just what I needed. I watched it in style with a cup of coffee. Now on to cutting up some wire. 73 AC7WY
Perfect! Wacth the follow up video, i comment on a couple of changes i made and a couple i will use in my next antenna
Will do thank you.
Nice scene there.
Thank you, its my k-2996 Activation Spot. i love it
Cool idea.
Glad you think so!
can you tell me about your telescoping mast? maybe it's in another video, but I just found your channel on this one so far :)
Thats a good video idea, i will put it on the list
Hi Frank -
Maybe you can help me...
- Which connectors did you use between each of the element?
- Did you do anything to prevent the segments from separating once they were under the load/strain of being up on the pole and sloping to the transformer?
Thank you & 73
Great video Tank, I especially love that you included the bloopers. \o/ DE KW4LU
It's what makes my channel great
Awesome pile up. KO4HPC 73
Thank you so much. ;P it was totally the antenna
Ape said you need a counterpoise!!
I read that ALOT of the chat. this antenna build didn't have one and i know. the coax will act or be the counter poise :(
Balderdash!
Bwhahaha, that's called common mode currentv when RF finds a path to ground. Some Dude named Lenz or maybe Kirchoff worked out some of that math. Lol but as long as the radio is fine and you make contacts good on you brother. Good on you for making this video instead of shilling for a sponsors ready made antenna. 😊
@@super66craig i will look into the math in running no counterpose. Sounds like a fun babbit whole
@@TankRadio Query Ape about that one. Or do a video with Ape on Counterpoises. Without a Counterpoise, then you should have an RF Choke before the radio.
What pole are you using?
The dx commander expedition mast
Was interested in the mast. Looking for a link.
dxcommander.com/product/10m-expedition-pole-dx-commander/
I love using mast in parks, Its hard to go back to tossing weights into tress.
@@TankRadio Understood was looking for one and wondered what you used.
Why linked?
This way i only have to run the correct sections to target a specific band. This way the antenna is a 1:1 with no tuner needed.
NICE !!! GD DX !!!! 73!!!de US4ET Victor...
Thank you
Hi all
Your always first in my book
End your crimp misery now Tank. Get yourself a ratcheted crimping tool: does a much better job. I had one of the crimping tools you used: a miserable experience.
I will look into this for the next build.

Nice job Frank!
Thank you for swinging by
