At all times when any work is being done on the tower

At all times except when climbing the tower

At all times except when belted firmly to the tower

Only when the tower exceeds 30 feet in height

Put on a climbing harness and safety glasses

Make sure that you wear a grounded wrist strap

Remove all tower grounding connections

All of the these choices are correct

T0B03-2014: Under what circumstances is it safe to climb a tower without a helper or observer?


When no electrical work is being performed

When no mechanical work is being performed

When the work being done is not more than 20 feet above the ground

T0B04-2014: Which of the following is an important safety precaution to observe when putting up an antenna tower?

Look for and stay clear of any overhead electrical wires

Wear a ground strap connected to your wrist at all times

Insulate the base of the tower to avoid lightning strikes

All of these choices are correct

T0B05-2014: What is the purpose of a gin pole?

To lift tower sections or antennas

To temporarily replace guy wires

To be used in place of a safety harness

To provide a temporary ground

T0B06-2014: What is the minimum safe distance from a power line to allow when installing an antenna?

So that if the antenna falls unexpectedly, no part of it can come closer than 10 feet to the power wires

Half the width of your property

The height of the power line above ground

1/2 wavelength at the operating frequency

T0B07-2014: Which of the following is an important safety rule to remember when using a crank-up tower?

This type of tower must never be climbed unless it is in the fully retracted position

This type of tower must never be painted

This type of tower must never be grounded

All of these choices are correct

T0B08-2014: What is considered to be a proper grounding method for a tower?

Separate eight-foot long ground rods for each tower leg, bonded to the tower and each other

A single four-foot ground rod, driven into the ground no more than 12 inches from the base

A ferrite-core RF choke connected between the tower and ground

A connection between the tower base and a cold water pipe

T0B09-2014: Why should you avoid attaching an antenna to a utility pole?

The antenna could contact high-voltage power wires

The antenna will not work properly because of induced voltages

The utility company will charge you an extra monthly fee

All of these choices are correct

T0B10-2014: Which of the following is true concerning grounding conductors used for lightning protection?

T0B11-2014: Which of the following establishes grounding requirements for an amateur radio tower or antenna?

Local electrical codes

FCC Part 97 Rules

FAA tower lighting regulations

Underwriters Laboratories' recommended practices

T0B12-2014: Which of the following is good practice when installing ground wires on a tower for lightning protection?

Ensure that connections are short and direct

Put a loop in the ground connection to prevent water damage to the ground system

Make sure that all bends in the ground wires are clean, right angle bends

All of these choices are correct
