1:1 balun qrp

I have a toroid from sotabeams , link below

Stated 7 and 6 turns , but I cant seem to see 7 and 6 turns on the picture . I’m guessing the picture is just method of winding rather than a exact diagram?

I always took it as an example of wrapping method.

Matt,

Take a look at this picture: https://cdn7.bigcommerce.com/s-qc1afpvf/product_images/uploaded_images/img-3509-1-.jpg

Or scroll to the bottom of the band hopper page and you can see an image of the suggested balun wrap from sotabeams: https://www.sotabeams.co.uk/band-hopper-iii-three-band-linked-dipole/

Hope this helps!
