If a pure resistance of 50 ohms is placed at the end of a length of 50 ohm transmission line:
  1. all power is reflected back along the line 2. the resistance will absorb all power reaching it 3. standing waves will appear on the line 4. the impedance of the line will change to 25 ohms

The characteristic impedance of a 20 ft piece of transmission
line is 52 ohms. If 10 ft were cut off, the impedance would be:
1. 13 ohms 2. 26 ohms 3. 39 ohms 4. 52 ohms

Any length of transmission line may be made to appear as an infinitely long line by:
1. shorting the line at the end 2. leaving the line open at the end 3. terminating the line in its characteristic impedance 4. increasing the standing wave ratio above unity

Losses occuring on a transmission line between the transmitter and the antenna results in:
1. less RF power being radiated 2. a SWR of 1:1 3. reflections occuring in the line 4. the wire radiating rf energy

If the characteristic impedance of the feedline
does NOT match the antenna input impedance then:
1. standing waves are produced in the feedline 2. heat is produced at the junction 3. the SWR drops to 1:1 4. the antenna will not radiate any signal

Coaxial feedline contains:
1. only one conductor 2. two parallel conductors separated by spacers 3. braid and insulation around a central conductor 4. four or more conductors running parallel

A balanced transmission line:
1. has one conductor inside the other 2. is made of two parallel wires 3. carries RF current on one wire only 4. is made of one conductor only

A 75 ohm transmission line could be matched to a 300 ohm feedpoint of an antenna:
1. with an extra 250 ohm leg of an antenna 2. by inserting a diode in one leg of the antenna 3. using a 4:1 balun 4. using a 4:1 trigatron in one leg of the antenna

TV twinlead feedline may be used for a feedline
in an amateur station. The impedance of this line is approx.:
1. 50 ohms 2. 70 ohms 3. 300 ohms 4. 600 ohms

The result of the presence of standing waves on a transmission line is:
1. maximum transfer of energy to the antenna from the transmitter 2. perfect impedance match between transmitter and feedline 3. reduced transfer of RF energy to the antenna 4. lack of radiation from the transmission line
