- ETA's base Certified Satellite Installer exam is 50 questions in two hours, with a 75% passing score.
- The published outline has 11 unweighted objectives, so study all of them rather than guessing at a blueprint.
- The official competency document dates to 2013; learn the theory it teaches, then map it to current equipment.
- Your free retake is valid for one year, but proctoring charges are still separate.
What You Are Actually Studying For
The Certified Satellite Installer (CSI) credential is issued by ETA International. The base exam tests the "Small Dish Capabilities" competencies, which ETA publishes as Section A (BASIC - CSI) of its Competency Requirements document. ETA states that these competency requirements are the basis for its examination questions, which makes that document the single most important thing to read before you open any other study material.
That document lists 11 numbered objectives. They are official competency headings, not weighted domains. No percentage-by-topic blueprint has been published, so anyone who tells you "Domain 6 is 20% of the test" is guessing. The sensible response to an unweighted outline is even coverage with extra time on your weakest areas. For a fuller walkthrough of each heading, see CSI Exam Domains 2026: Complete Guide to All 11 Content Areas.
If you are still orienting yourself on what the credential is and who it is for, start with What Is CSI Certification? and come back here once the basics are settled.
Exam Format, Fees, and Logistics
Knowing the container your knowledge has to fit into removes a surprising amount of anxiety. Here is what ETA's current published sources state for the base exam.
| Item | What ETA Publishes |
|---|---|
| Base exam fee | $80 |
| Number of questions | 50 |
| Time limit | Two hours |
| Passing score | 75% |
| Hands-on assessment | None |
| Certification term | Four years, with maintenance required |
| Retake | One free retake within one year (proctoring charges separate) |
| Endorsement exams | $65 each, separate exams |
Two clarifications matter here. First, a 75% passing threshold is a cut score, not a pass rate; ETA does not publish how many candidates pass, and you should be skeptical of any site that quotes a number. We cover what is and is not known in CSI Pass Rate 2026: What the Data Shows, and the scoring mechanics in CSI Passing Score 2026: Exactly What You Need to Pass. Second, ETA's listing discounts the base exam by half when you take it alongside an endorsement in the same session. That is a pricing perk, not a broadening of the base exam's content.
On the arithmetic: at 75% of 50 questions, you need roughly 38 correct answers. That leaves a cushion of about a dozen misses, which is generous enough that you do not need perfection, but not so generous that you can skip an entire objective and hope to recover elsewhere.

The 2013 Outline Problem: Legacy vs. Present-Day Gear
This is the part most study guides skip, and it is where thoughtful candidates can gain an edge. The official competency document carries a 2013 copyright date. A 2026 article date does not mean the outline was revised in 2026; no revision has been verified. The outline reflects the small-dish landscape of its era, so some of the products and standards it names are legacy technology.
What does that mean practically?
- Principles are durable. Geostationary orbit geometry, azimuth and elevation, polarization, signal-to-noise concepts, coax behavior, grounding, and ladder safety do not expire.
- Product names are not. When the outline references a specific receiver type, connector scheme, or service, treat it as a window into the concept being tested, then ask what the modern equivalent is.
- Do not assume the exam is only legacy trivia, and do not assume it is current-product trivia. Because no source verified exhaustive coverage beyond the published competencies, the safest approach is to master the competency headings and be able to explain each concept in both its older and present-day form.
Domain-by-Domain Study Priorities
Below are the 11 objectives, grouped by how they tend to behave when you study them. Remember the headings are unweighted, so the grouping reflects study strategy, not exam weight.
Foundations and Hardware
Domains 1 and 2: Satellite Communications History and Theory; Satellite Dish Reflectors
This is where vocabulary and geometry live. Expect to need a working grasp of how satellites hold position, why dish shape matters, and how reflector characteristics affect signal capture.
- Orbital concepts and why dishes are aimed at a fixed point in the sky
- Reflector types, sizes, and how size relates to signal gain and rain performance
- Common reflector mounting and surface-care considerations
Domain 5: Satellite Dish Feed-horns, LNBs and LNBFs
The feed assembly is where the dish's collected energy becomes a usable signal. Know what each component does and what a failing one looks like.
- The role of the feed-horn versus the LNB versus the combined LNBF
- Polarization handling and how skew adjustment relates to it
- Why LNB quality and condition show up in signal symptoms
Signal Path
Domains 3 and 4: Cabling; Amplifiers
Signal path questions reward practical thinking. Loss, connectors, and amplification are about keeping a weak signal usable between dish and receiver.
- Coax characteristics, run-length considerations, and connector quality
- Why water ingress and poor terminations cause intermittent problems
- When amplification helps and when it only amplifies noise
Planning and Receiving
Domain 6: Satellite System Installation, Site Surveys
A site survey is the difference between a clean install and a callback. This objective is intensely practical and rewards anyone who has actually stood on a roof looking for a clear southern arc.
- Line-of-sight clearance and obstruction assessment
- Mount selection and location tradeoffs
- Aiming inputs: location, elevation, azimuth, and how they are determined
Domains 7 and 8: Satellite Receivers, Digital Technology; Interfacing With Other Consumer Electronics Equipment
These two cover what happens after the signal reaches the house: digital signal concepts, receiver behavior, and connecting the system to televisions and other gear.
- Digital versus analog concepts and what digital transmission changes
- Receiver setup and the inputs and outputs used to connect other equipment
- Interface compatibility between older and newer consumer electronics
Data, Diagnosis, and Safety
Domain 9: Transmission, Internet Systems
Satellite is also a data transport. Understand at a conceptual level how internet delivery over satellite differs from one-way television delivery.
- Two-way versus one-way concepts
- Why latency is inherent to the geometry of geostationary links
Domains 10 and 11: Troubleshooting, Repairs, Sun Outage; Safety
These are the objectives most likely to show up as scenario questions: a symptom is described and you pick the cause or the correct response. Safety questions tend to have unambiguous right answers, which makes them some of the most recoverable points on the exam.
- Distinguishing a sun outage from a genuine fault
- Systematic troubleshooting order: signal source to dish to cable to receiver
- Ladder, roof, electrical, and grounding safety practice
If you want a single printable recap of the facts that recur across these objectives, the CSI Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for the last week of review.
Field Skills That Translate Into Test Answers
Because the exam has no hands-on component, everything is demonstrated through written responses. But installers have an advantage: much of this exam is codified field intuition. Here is how to convert job experience into points.
- Narrate your installs. After each job, say aloud why you picked the mount location, how you confirmed clearance, and what you checked first when signal was weak. Those narrations are your troubleshooting answers.
- Name the failure mode. When a customer reports "pixelating in the afternoon," practice mapping symptom to cause: a marginal signal, water in a connector, a loose mount, a sun-outage window, or vegetation growth. Scenario questions reward this habit.
- Learn the vocabulary behind the shorthand. Field crews say "peak it" or "skew it." The exam says polarization, azimuth, and elevation. Translate shorthand into formal terms.
- Respect the safety objective. Experienced installers sometimes treat safety as common sense and under-study it. Read it deliberately; a missed safety question is an avoidable loss.
Key Takeaway
If you have no field experience, build mental scenarios instead: picture a roof, a tree line to the south, a long coax run, and a customer complaining of dropouts. Walk each objective through that picture until the cause-and-effect logic is automatic.
A Six-Week Plan Built Around the 11 Objectives
Generic schedules are everywhere; this one is tied to how the objectives depend on each other. Foundations come first because later topics assume them, and troubleshooting comes late because it draws on everything else. Adjust the pacing to your own calendar and experience.
Theory and Reflectors (Domains 1-2)
- Read the official competency headings in full
- Build vocabulary: orbit, azimuth, elevation, polarization, gain
Signal Path (Domains 3-5)
- Cabling, connectors, amplifiers, then feed-horns, LNBs, and LNBFs
- Trace one signal from dish to receiver and note where loss can occur
Site Surveys (Domain 6)
- Practice obstruction and mount-location reasoning
- Work through aiming inputs and how they are determined
Receivers, Interfaces, and Data (Domains 7-9)
- Digital concepts, receiver connections, other consumer electronics
- Internet-over-satellite concepts
Troubleshooting and Safety (Domains 10-11)
- Symptom-to-cause drills, including sun outage recognition
- Safety review with no shortcuts
Mixed Practice and Gap Closing
- Timed sets that mix all 11 objectives
- Revisit every objective where you missed questions
For the practice portion, run timed sets on the CSI Exam Prep practice test site, then log every miss by objective. A pattern in the log tells you where to spend week six far better than a gut feeling does. If you want a sense of whether your preparation level matches the challenge, How Hard Is the CSI Exam? Complete Difficulty Guide 2026 offers a grounded view.
Exam-Day Rules and Scheduling
Logistics trip up well-prepared candidates more often than content does. ETA's published testing guidance includes the following.
- Photo identification is required. Bring valid ID.
- Scratch paper and calculators have rules. Scratch paper and nonprogrammable or scientific calculators are permitted subject to the stated rules, and used scratch paper must be returned.
- Phones are excluded. Do not plan on having yours.
- Remote proctoring has its own steps. It runs through ExamRoom.AI, requires registration through ETA, and adds $16 for a two-hour exam, including an otherwise free eligible retake. Verify current technical requirements when you schedule, since they can change.
- Proctor access varies. You test through an ETA Certification Administrator, so locate an administrator before you commit to a study deadline.
Scheduling specifics, such as how to find an administrator and what lead time to expect, are covered in CSI Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
After You Pass: Maintenance, Endorsements, and Journeyman
Passing starts a four-year term, and it is worth knowing what keeping the credential involves before you invest in it. For this non-hands-on credential, ETA's published maintenance route requires a maintenance form and a fee of $25 per year or $100 per four-year cycle, with either 10 continuing-education hours annually (40 over four years) or qualifying employer verification. Do not confuse this with the separate rules for hands-on credentials.
| Path | What It Involves |
|---|---|
| Standalone CSI | The base exam described in this guide; no prior CETa required |
| Endorsements | Antenna, C/Ku, Commercial, and SMATV are separate $65 exams, not extra base domains |
| Journeyman | A separate pathway combining CSI with CETa or GCT1 plus two years of training or experience |
Keep these separate in your planning. Studying for endorsements does not change what is on the base exam, and Journeyman status is a distinct designation rather than an upgrade you receive automatically. If you are weighing whether the investment pays off, Is the CSI Certification Worth It? Complete ROI Analysis 2026 and CSI Salary Guide 2026: Complete Earnings Analysis are honest about the difference between what installers earn in general and any premium that can actually be attributed to the certificate.
One caution for readers comparing options: the SBCA's Satellite Fundamentals program is a different credential from a different organization, and its exam specifications do not apply to ETA's CSI. Do not mix study materials between the two.
Frequently Asked Questions
ETA lists the base Certified Satellite Installer exam as 50 questions with a two-hour limit and a 75% passing score. There is no hands-on assessment. That passing score is a threshold, not a population pass rate.
No weighting has been published. The 11 objectives come from ETA's Competency Requirements document and are unweighted official headings, so plan to cover all of them rather than concentrating on a guessed-at favorite.
The competency document carries a 2013 copyright date, and no later revision was verified. Its core principles remain sound, but some named products are legacy. Learn the principle behind each objective and be ready to relate it to present-day equipment.
ETA offers one free retake within one year, though proctoring charges remain separate. Remote proctoring through ExamRoom.AI adds $16 for a two-hour exam, including an otherwise free eligible retake. Use your first attempt's weak areas to direct your second round of study.
Standalone CSI does not require prior CETa certification. The badge criteria mention at least six months working in the profession and Code of Conduct compliance. Journeyman status is a separate pathway that adds CETa or GCT1 and two years of training or experience.
When you are ready to test your recall under realistic conditions, work through timed sets on the CSI Exam Prep practice tests, and keep the domains guide open as your checklist until every objective feels routine.
