40 Meter Half-Wave Rotatable Dipole Antenna

[@che59v]

The more I look at this video the more I appreciate my multi band wire loop antenna. Thank for the video we all hope this dipole will live to your expectations.

[@n5yiz]

Thanks, we'll see what happens. Unfortunately, I can only get it about 40ft in the air. 73

Most of us don't have enough real estate to make this a practical proposition.

[@michaelosterloh8033]

Great video! Thank you so much. Can you give me a link to the trader for that stuff?

[@tomking8597]

Just wanting to see it in action.

[@n5yiz]

coming soon

[@Andrew-yx7sf]

Can you post a materials list please?

I am wanting to build one for 60 meters. Be about 100' long so I was planning on starting out with 3" tubing and tapering down from there. Plan would be to get it up to optimum height above ground which would be around 110 feet. Nice work and thanks for the video.

[@n5yiz]

That's going to be incredible. If you have the tower to support the weight, you'll have no problem getting to the required length startng with 3" tube. I used 1.25" primary and worked down to a 3/8 tube and that got me to 32.5' easy. It droops without the support truss, but it's not even close to collapsing under it's own weight. Using a 3" primary you have a lot of headroom to get to 100 feet. I honestly just finished drilling and bolting the tubes for the 40m last week. I plan on using it during field day. I did change a couple of things since I made that video. I'll make another showing the revisions.

@@n5yiz looking forward to the update video! My project will be a slow moving one because first I will have to get a tower up that high. I already have plenty of tower. I just need an approved place to put it and the time!

[@BobGarrett66]

This is awesome! Can you put 200W through this antenna? What would be the maximum wattage? Thanks for the video!!

[@n5yiz]

It'll do legal limit no problem. You would have to use a the appropriate coax and a higher wattage balun.

[@BobGarrett66]

@@n5yiz Perfect! Thanks for the reply. 73.

[@nathanjackson6874]

Kind of new and loosely following. Idea that popped in my mind with the 20 meter, and adding this…so here goes. How would it look, feel, and perform, from the same vertical mast? Obviously feedlines will be an issue. Single Feedline per band or some type of HF diplexer or triplexer.

[@n5yiz]

Actually, what you suggested is what I am planning on doing eventually. I think if they are stacked 90 degrees to each other, it would work perfect.

[@nathanjackson6874]

@@n5yiz thanks for the reply and can’t wait to see the overall finished product! Another idea that popped in my mind, just after this was…. How about each dipole on the same boom? If would take some technical work with spacing, and I realize some directivity would happen. Now I I’m curious enough to go grab some modeling software and see how they look in the same horizontal plane! Ahh the wonders of the hobby, always something to keep the brain engaged!

[@michaelwenmanK7USN]

overkill imho with the upper "truss". could have just done a cap on the mast with an eyebolt in it, then run some Dacron with S hooks from there to your support point on the antenna and used a hose clamp there.

[@luckydubeinrc5165]

subbed wanna see it it in the air :) 73's zs2cx

[@W4TRI_Ronny]

How are you getting around HOA? Great stuff!!!

[@n5yiz]

No HOA where It'll be installed.

[@richarde735]

when are you going to build the 80m version?

[@n5yiz]

I actually thought about it. Will need muffler pipe.

[@tomperone9338]

I'm holding out for the 160m version. 😁

[@jasonvincent1818]

I notice every time I get tubing, it's about .020 off in either direction......

[@n5yiz]

I feel your pain. Same experience.
