TTT-1 Appurtenance installation Practice Test

10 questions · 20% of the real TTT-1 exam · instant scoring · explanations cite the standard

Appurtenance installation is 20% of TTT-1 — RRUs, fiber, coax hangers, azimuth and tilt, labeling, torque stripes, dropped-object control and the sweep that proves the work. Ten questions with explanations.

10 appurtenance installation questions

Question 1 of 10

RRU stands for:

Show answer and explanation

Correct answer: B. The RRU (or RRH, remote radio head) sits near the antenna and connects to the baseband unit by fiber, with DC power from the shelter.

Question 2 of 10

Fiber jumpers to an RRU require:

Show answer and explanation

Correct answer: B. Fiber is damaged by tight bends and contamination. Caps stay on until the moment of connection; connectors are inspected and cleaned before mating.

Question 3 of 10

Coax hangers are installed:

Show answer and explanation

Correct answer: B. Too few hangers lets the cable's own weight load the top connector and allows wind movement that fatigues the jacket.

Question 4 of 10

Antenna azimuth is verified with:

Show answer and explanation

Correct answer: B. Steel deflects a magnetic compass. Carriers specify azimuth tolerance and expect instrument-based verification with documentation.

Question 5 of 10

Mechanical downtilt is set by:

Show answer and explanation

Correct answer: B. Mechanical tilt is physical and measured on the antenna face. Electrical tilt is internal and can be remote (RET). Total tilt is the sum.

Question 6 of 10

Lines should be labeled:

Show answer and explanation

Correct answer: B. An unlabeled line gets traced by someone at 200 feet on a cold morning. Labeling is part of the installation, not an extra.

Question 7 of 10

A jumper between the main line and the antenna is used because:

Show answer and explanation

Correct answer: B. Large corrugated coax cannot bend to the antenna port. A flexible jumper makes the connection within bend-radius limits.

Question 8 of 10

After torqueing an antenna mount bolt to spec, a torque stripe (witness mark) is applied to:

Show answer and explanation

Correct answer: B. A continuous stripe across nut, bolt and base. If the stripe breaks, something moved.

Question 9 of 10

Dropped-object prevention when working with hardware at height includes:

Show answer and explanation

Correct answer: B. A nut dropped from 150 feet is lethal. Everything is tethered or contained; nothing rests on the steel.

Question 10 of 10

The sweep test (return loss / VSWR) is performed:

Show answer and explanation

Correct answer: B. The sweep is the proof of a good installation and the baseline for future troubleshooting. Results are part of the close-out package.

Frequently asked questions

How much of the NWSA TTT-1 exam is appurtenance installation?

20%, per the Candidate Handbook REV 10/25 content outline. The full TTT-1 exam is 85 questions · 90 minutes.

Is the NWSA exam computer-based?

Yes. Since January 2024 every NWSA certification exam is delivered by Online Remote Proctoring (ORP) — you take it on your own computer with a live proctor. The practical exam component was discontinued at the same time.

What score do I need to pass the NWSA exam?

NWSA does not publish a passing score. Exams are criterion-referenced and the cut score is set by a panel of subject-matter experts; results are reported as pass/fail with a domain-by-domain breakdown. Any site quoting a specific percentage is guessing.

How much does the NWSA exam cost?

$274 for every NWSA certification — TTT-1, TTT-2, A&L, Foreman and ARC. Retakes are the same $274, with a 30-day wait between attempts. Fees are set by NWSA and can change; nws-a.org is the authority.

Exam facts on this page are from the NWSA Candidate Handbook, CH REV 10/25. Fees, formats and rules change — the handbook is the authority. NWSA Study Guide is independent and is not affiliated with, endorsed by, or recognized by the National Wireless Safety Alliance.
