1:1 Balun w Choke

This box holds a 1:1 balun and a choke, I used FT240s and a mix 61 for the 1:1 and a mix 31 for the choke as per the Palomar website.

I ran window line from the dipole down to the ground.

I know this looks like a 9:1 they are wound the same but are actually connected totally differently.

You wont have to worry about the infill as the walls are thin enough that with 3 perimeters you do not have to worry about infill.
