worked well!

@skobkin

Can you add your specs from the antenna calculator for us to be able to compare if it'll be suitable in slightly different conditions?

The designer has replied

@bkolicoski

The specs are in the video details linking to my website but here is the link here as well: https://www.tastethecode.com/3d-printed-yagi-antenna-for-long-range-lora-communication

Replying to @bkolicoski :

I see, thanks! Looks like if I want to make 6 element antenna, I can just make your model a bit longer. All points would be the same except the new one. Thank you!

Great video, and a good starting point for me to make a US build version of this. Thanks for sharing.

The designer has replied

@bkolicoski

I'm glad you liked it.

@lallenlowe

care to share the US version?

@Soupbones

Can you add a design for 915Mhz? Thats what the rest of the planet apart from Europe use..

The designer has replied

@bkolicoski

I don't have one at the moment but you can use the calculator that I used and make one for yourself, or even get the attached fusion file and modify it with the dimensions from the calculator. https://3g-aerial.biz/en/online-calculations/antenna-calculations/dl6wu-yagi-uda-antenna-online-calculator

@Rcarroll1985

i used the site, but I was wondering what the distance was for the holes. on the site, it has the overall length of 224mm, with a boom diameter of 15mm....can you tell me what those dimensions for the holes and overall length to appropriate to 915 mhz. i am very new to building antennas and have only managed a GP 915...but a yagi is what I have been looking for. thanks for any feedback!

this does just fit on the A1 mini.

The designer has replied

@bkolicoski

Great, thanks for letting us know. I only have the P1P so I designed to fit on it but I guess with some angle adjustment it fits the A1 as well.

@user_2134754019

can you edit the 3D model to diameter equal to 3mm My rod is that much and i cant edit it or find the propper width for them....

(Edited)

The designer has replied

@bkolicoski

3mm rod will definitely change the calculation so basically an entire new model is needed. You can try and drill out the holes to 3mm but I'm not recommending that. You can get the rods from solid copper wire 12 AWG. Just make sure you straighten them as much as you can.
