NWSA Telecommunications Tower Technician 1 (TTT-1)

Question 1

When performing a sweep test (or VSWR test) on a newly installed coaxial cable run, what is the primary purpose of this test?

To measure the cable's resistance to weather and UV exposure. To verify the cable and its connectors meet performance specifications across a range of frequencies. To determine the maximum power handling capacity of the transmission line. To locate sources of Passive Intermodulation (PIM) caused by loose connections.

Correct Answer:

To verify the cable and its connectors meet performance specifications across a range of frequencies.

Question 2

A technician is installing antenna mounting hardware that specifies a torque value of 60 ft-lbs for the 5/8" bolts. The technician only has a torque wrench that measures in inch-pounds. What value should the technician set the wrench to?

600 in-lbs 120 in-lbs 720 in-lbs 660 in-lbs

Correct Answer:

720 in-lbs

Question 3

Which of the following best describes Passive Intermodulation (PIM) in an antenna and line system?

A measure of the signal reflected back towards the transmitter due to an impedance mismatch. Unwanted interference signals generated when two or more carrier frequencies mix at a non-linear junction, such as a corroded or loose connector. The loss of signal strength (attenuation) as it travels along the length of a coaxial cable. External radio frequency interference from nearby broadcast towers or other cell sites.

Correct Answer:

Unwanted interference signals generated when two or more carrier frequencies mix at a non-linear junction, such as a corroded or loose connector.

Question 4

During the installation of a new transmission line on a tower, a technician must use a hoisting grip to lift the cable. Where should the hoisting grip be attached to the cable for a vertical lift?

At the midpoint of the cable to balance the load. Near the connector at the top end of the cable. Loosely around the cable jacket to allow for movement. Several feet below the connector to avoid stress on the connection point.

Correct Answer:

Near the connector at the top end of the cable.

Question 5

A tower crew is tasked with weatherproofing a 4.3-10 coaxial connector on an antenna jumper. What is the standard, multi-layer method for ensuring a long-lasting, watertight seal?

A single, thick layer of electrical tape wrapped tightly around the connector. Injecting silicone sealant directly into the connector threads before tightening. Applying a layer of vinyl tape, followed by a layer of butyl mastic tape, and finished with an outer layer of vinyl tape. Using a heat-shrink tube without any underlying tape layers.

Correct Answer:

Applying a layer of vinyl tape, followed by a layer of butyl mastic tape, and finished with an outer layer of vinyl tape.
