LICENSE QUIZ #253

de Steve, AE8AT

The quiz topic this week is feedlines. I probably should save this topic for
Thanksgiving, but it would probably land as well as a WKRP turkey drop.

radio?

A. 8 ohms
B. 50 ohms
C. 600 ohms
D. 12 ohms

G9A01 Which of the following factors determine the characteristic impedance
of a parallel conductor feed line?

A. The distance between the centers of the conductors and the radius of the
conductors
B. The distance between the centers of the conductors and the length of the
line
C. The radius of the conductors and the frequency of the signal
D. The frequency of the signal and the length of the line

E9E06 Which of these feed line impedances would be suitable for constructing
a quarter-wave Q-section for matching a 100-ohm loop to 50-ohm feed line?
