T0B01:

When should members of a tower work team wear a hard hat and safety glasses?

1. At all times except when climbing the tower
2. At all times except when belted firmly to the tower
3. At all times when any work is being done on the tower
4. Only when the tower exceeds 30 feet in height

T0B02:

What is a good precaution to observe before climbing an antenna tower?

1. Make sure that you wear a grounded wrist strap
2. Remove all tower grounding connections
3. Put on a carefully inspected climbing harness (fall arrester) and safety glasses
4. All of these choices are correct

T0B03:

Under what circumstances is it safe to climb a tower without a helper or observer?

1. When no electrical work is being performed
2. When no mechanical work is being performed
3. When the work being done is not more than 20 feet above the ground
4. Never

T0B04:

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

1. Wear a ground strap connected to your wrist at all times
2. Insulate the base of the tower to avoid lightning strikes
3. Look for and stay clear of any overhead electrical wires
4. All of these choices are correct

T0B05:

What is the purpose of a gin pole?

1. To temporarily replace guy wires
2. To be used in place of a safety harness
3. To lift tower sections or antennas
4. To provide a temporary ground

T0B06:

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

1. Half the width of your property
2. The height of the power line above ground
3. 1/2 wavelength at the operating frequency
4. Enough so that if the antenna falls unexpectedly, no part of it can come closer than 10 feet to the power wires

T0B07:

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

1. This type of tower must never be painted
2. This type of tower must never be grounded
3. This type of tower must not be climbed unless retracted or mechanical safety locking devices have been installed
4. All of these choices are correct

T0B08:

What is considered to be a proper grounding method for a tower?

1. A single four-foot ground rod, driven into the ground no more than 12 inches from the base
2. A ferrite-core RF choke connected between the tower and ground
3. Separate eight-foot long ground rods for each tower leg, bonded to the tower and each other
4. A connection between the tower base and a cold water pipe

T0B09:

Why should you avoid attaching an antenna to a utility pole?

1. The antenna will not work properly because of induced voltages
2. The utility company will charge you an extra monthly fee
3. The antenna could contact high-voltage power lines
4. All of these choices are correct

T0B10:

Which of the following is true when installing grounding conductors used for lightning protection?

1. Only non-insulated wire must be used
2. Wires must be carefully routed with precise right-angle bends
3. Sharp bends must be avoided
4. Common grounds must be avoided

T0B11:

Which of the following establishes grounding requirements for an amateur radio tower or antenna?

1. FCC Part 97 Rules
2. Local electrical codes
3. FAA tower lighting regulations
4. UL recommended practices

T0B12:

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

1. Put a loop in the ground connection to prevent water damage to the ground system
2. Make sure that all bends in the ground wires are clean, right-angle bends
3. Ensure that connections are short and direct
4. All of these choices are correct

T0B13:

What is the purpose of a safety wire through a turnbuckle used to tension guy lines?

1. Secure the guy if the turnbuckle breaks
2. Prevent loosening of the guy line from vibration
3. Prevent theft or vandalism
4. Deter unauthorized climbing of the tower
