Coax + Ladder Line

Is it OK to place a 4:1 balun just outside
of the window for the transition?

Given the impedance seen by the balun, is a 4:1
transformation what you want?

If the impedance seen by the balun is 10 ohms,
for instance, do you think taking the impedance
down to 2.5 ohms is an improvement?
