Easiest way to verify the actual length required is to
remove the loop from the can (or adjust it for minimal

What band are you dealing with and its frequency spread?
The length of cable including the loop's effective length and the
star's contribution should equal an electrical odd multiple of a
quarter wavelength. Easiest way to verify the actual length required
is to remove the loop from the can (or

OK, we'll try to help.
I am interested in the maths and formula involved in cable
