As shown, a quarter-wavelength sleeve is placed around
the outer conductor of coaxial line and connected to it at
x
The outer conductor of coaxial line no longer has zero
impedance to ground at y
One of the wires of the balanced line may be connected
to it without fear of being short- circuited to ground
The other balanced wire is connected to the inner
conductor of the coaxial line
Any balanced load, such as the simple dipole antenna,
may now be placed upon it as shown in figure
