Paul, the usual place to connect B+ is at a point of minimum rf voltage.
Depending on the design, a stripline could be 1/4 wavelength, 1/2
wavelength or 3/4 wavelength. This is the electrical length and a good part of
the
electrical length is inside the tube and tune C.
Typically the B+ is fed through an rf choke. It helps minimize interaction
between the choke and stripline if the choke is positioned 90 degrees from
the stripline.

Hello builders,
A quick question about strip line design.
Does it matter or make much difference where the B+ is attached to the
stripline? I've seen a couple designs where it is connected close to the
tube, others where it is half way down the strip line.
Is there any rhyme or reason behind where B+ attaches?
Thanks,
Paul
