NWSA Tower Structures and Inspection 2

Question 1

What are the three main types of telecommunications tower structures?

Accepted Answer

Self-supporting lattice, guyed, and monopole

Answer

Wood, plastic, and concrete

Answer

Single-pole, double-pole, and triple-pole

Answer

Residential, commercial, and industrial

Question 2

What structural deficiency would require immediate work stoppage during a tower climb inspection?

Accepted Answer

Buckled or severely bent main structural members indicating potential structural compromise

Answer

Minor surface rust on a non-structural element

Answer

A missing climb peg above 100 feet

Answer

Faded paint on the tower identification sign

Question 3

How does ice loading affect tower structural integrity?

Accepted Answer

Ice adds substantial weight to all structural members and equipment, increases wind loading due to larger cross-section, and can cause member failure

Answer

Ice has no significant effect on towers

Answer

Ice only affects guy wires

Answer

Ice damage only occurs in arctic regions

Question 4

What is the purpose of the TIA-222 standard in relation to telecommunications towers?

Accepted Answer

It establishes structural design, analysis, and inspection requirements for antenna supporting structures and antennas

Answer

It regulates cell phone pricing

Answer

It sets radio frequency power limits

Answer

It determines tower paint colors

Question 5

During a tower inspection, what should be checked at the foundation level?

Accepted Answer

Concrete condition, exposed rebar, soil erosion, grout pad integrity, anchor bolt condition, and drainage

Answer

Only the paint condition

Answer

Just the tower identification plate

Answer

Foundation inspection is only needed during construction

Question 6

What is the significance of guy wire tension readings during a guyed tower inspection?

Accepted Answer

Incorrect tension indicates the tower may be out of plumb, unevenly loaded, or have anchor problems that affect structural integrity

Answer

Guy wire tension doesn't affect tower performance

Answer

Tension readings are only needed during installation

Answer

Only the top guy wires need tension checking
