Replying to @user_658605676 :

Thank you, I will print it now and let you know results.

It works really well. You need a measuring instrument to be able to cut the dipole to the right length. You can e.g. use a Nano VNA to achieve optimal SWR.

Is this with 5 or 7 wires? I just printed it. Looks good, but I see 5 wires on photo, 7 in description.
