Question

I am stumped with this question related to transmission line calculations and the use of the Smith chart -

If you have a 300 ohm transmission line terminated with an antenna that presents a (400 ohm - j 600 ohm) load impedance:

What is the normalized load admittance?
How far from the load should a short circuit stub be placed to match the load?
How long should the stub be?
What is the VSWR before matching at the load?
What is the VSWR after matching at the input of the transmission line?
