Are you ready to find out why center-loading takes
more coil in a mobile antenna than does base loading?

Take the 10 degrees of 100 ohm line and move 5
degrees of it to the other end of the stub.

From this:

---43.4 deg 600 ohm line---+---10 deg 100 ohm line---open

To this:

--5 deg 100 ohm line--+--600 ohm line--+--5 deg 100 ohm line--open

Now how many physical degrees of 600 ohm line is needed
to make the stub electrically 1/4 wavelength?
