completes the statement or answers the question. Indicate your solution by

circling the letter opposite the correct answer in the subcourse booklet.

1.

At radar and microwave frequencies, coaxial line sections are used in

preference to two-wire sections because their

a.

velocity factor is higher.

b.

radiation losses are lower.

c.

dielectric is more efficient.

d.

circuits can be balanced in respect to ground.

2.

Although the electrical properties of

a transmission line are

distributed evenly along the line, they

can be represented as an

infinite number of small values of series.

a.

inductance and capacitance plus shunt resistance and conductance.

b.

resistance and conductance plus shunt inductance and capacitance.

c.

inductance and resistance plus shunt conductance and capacitance.

d.

conductance and capacitance plus shunt inductance and resistance.
