yagi Self built 'X-wing' yagi antenna

I thought people here would enjoy seeing the progress so far on building a complex 'X-wing' antenna. I'm still testing and figuring it out, but this is looking good so far.  I welcome any thoughts you have.

Yes, it is an interesting antenna, but you can also give the size ... ??? !!!

For this antenna would be interesting to do a simulation ... ???

I only recently got a CAD program working on the computer.  Sadly there isn't anything that I'm able to figure out for linux (so 2nd older laptop w/ windows).  I'll share a 3D model and dimensions soon.

Your own design is incredibly beautiful and elegent.  That's a much higher level of construction skill.

This looks so interesting. I would be curious to know what software you used for this.  That looks like the 'Autocad' XYZ symbol, but I've never heard of Autocad doing waveguide modeling.  Being able to model before building would be great in helping to build a 15dbi antenna.
I might go with a yagi inside a cantenna, which McNeal has demonstrated.

It"s CST STUDIO SUITE  - modeling three-dimensional electromagnetic structures.

I'm really flattered that you modeled my antenna.  I'm going to look into seeing if CST offers a trial version of their software.  Thank you for all the input and advice.

In the meantime I have another question before building a yagi-cantenna.
This video that McNeil made, shows his yagi attached to a BNC connector which is then soldered to a pigtail.


It seems to me that it would be more practical to solder the two ends from a disassembled dipole antenna in order to make the connection to a router.  The reason that I'm asking so much, is that I don't know how easy it will be to troubleshoot a problem. I tried connecting the yagi above to a cellphone using a long a long cable with a zigzag at the end as a couple of Indian people show.  But it gave no advantage that I could tell.  I wont necessarily know if a problem is due to the router, the cable, or the antenna design

Yagi-Cantena of McNeil is not exactly a good antenna --- a few years ago I did such a simulation and was not conforming

That's very interesting to hear.  I don't see any measurements in that video as there have been in other ones that he's made.

I instead used the measurements from this site - https://www.ab9il.net/wlan-projects/wifi6.html

everything is connected with screws, so if I (cough) screw up, then it's easy to switch out the yagi.

I took your suggstion with the dipole antenna and soldered each of the two wires one to the copper plate on top and one to the copper plate beneath. Then soldered wire btwn them forming a loop. I wasn't able to find actual metal tubing that was large enough, but found a 4in cardboard tube and rolled a cpl layers of aluminum flashing to reflect radio waves.  I'll try to get measurements off the cad program if you want.

Thank you.  I'll look into it.

FYI - I'm reading this site with my X-wing antenna about 75meters away from the building.  Hopefully I can work on an antenna that will extend to 90 meters
