Lesson 1Line-of-sight analysis: identifying trees, buildings, roof edges, and seasonal foliage impactLearn to evaluate line-of-sight by identifying trees, buildings, roof edges, and other obstacles. You will consider the satellite arc, possible dish positions, and seasonal changes in foliage like harmattan dust or rainy season growth that can impact long-term signal quality in Nigeria.
Using sighting tools to trace satellite pathsIdentifying current physical obstructionsEstimating seasonal foliage growth impactComparing alternative dish mounting spotsDocumenting LOS risks in site notesLesson 2Pre-work check: paperwork, permits, customer confirmation, and site photos for baseline documentationBefore starting, confirm all paperwork, permits, and customer details as required by local Nigerian authorities. This section explains verifying job scope, taking baseline photos, and recording existing damage or hazards to protect both the technician and client from disputes.
Reviewing work orders and job scopeConfirming customer identity and expectationsChecking permits and property approvalsTaking baseline photos of site conditionsRecording pre-existing damage and hazardsLesson 3Inspecting coaxial cables, connectors, splitters, multiswitches, and indoor terminationThis section covers inspecting coaxial cables, connectors, splitters, and multiswitches for damage, moisture, and signal loss, especially in humid Nigerian weather. You will also review indoor terminations, labelling, and strain relief to guarantee long-term reliability.
Identifying kinks, crushing, and UV damageChecking connectors for corrosion and loosenessEvaluating splitters and multiswitch placementInspecting indoor wall plates and terminationsLabeling cable paths for future serviceLesson 4Using tools and apps for preliminary azimuth/elevation/skew lookup (satellite lookup websites, compass apps)Learn to use satellite lookup websites and mobile apps to get azimuth, elevation, and skew values suited to Nigerian locations. This covers map alignment, magnetic versus true north adjustments for local variations, and validating readings against on-site conditions.
Choosing reliable satellite lookup websitesUsing compass and inclinometer appsUnderstanding magnetic vs true northChecking skew values for selected satellitesCross-checking app data with field realityLesson 5Visual inspection of dish, mount, mast, and wall/roof bracketsCarry out a thorough visual inspection of the dish, mount, mast, and brackets. Learn to spot misalignment, loose fittings, rust from humid air, and water damage that could affect safety, pointing accuracy, or the stability of the system over time in Nigeria.
Checking dish alignment and visible warpingInspecting mast plumb and rigidityExamining wall and roof bracket anchoringIdentifying rust, cracks, and metal fatigueAssessing sealant and water intrusion pointsLesson 6Personal protective equipment and PPE checklist: harnesses, anchors, helmets, gloves, and footwearUnderstand the required personal protective equipment for satellite work in Nigeria, including harnesses, anchors, helmets, gloves, and sturdy footwear. Learn to use a PPE checklist to verify condition, proper fit, and compliance before each job to prevent accidents.
Selecting fall arrest harnesses and lanyardsChoosing anchors and lifelines for roofsUsing helmets, gloves, and eye protectionSelecting slip-resistant, insulated footwearCompleting and storing PPE checklistsLesson 7Roof and balcony access planning: ladder placement, fall hazards, and rescue considerationsPlan safe access to roofs and balconies by selecting stable ladder spots, managing fall hazards, and preparing rescue plans. Learn to assess surfaces, anchor points, weather risks like sudden rains, and local Nigerian regulations before climbing.
Selecting safe ladder locations and anglesSecuring ladders to structures and anchorsAssessing roof surfaces and load capacityIdentifying fall hazards and exclusion zonesPlanning rescue routes and emergency accessLesson 8Assessing dish condition: reflector, feedhorn/LNB, bolts, corrosion, and structural integrityAssess the condition of the reflector, feedhorn or LNB, and all bolts. This section addresses corrosion from coastal humidity, UV damage from intense sun, water ingress, and structural weaknesses that may need repair, replacement, or re-anchoring in Nigerian conditions.
Inspecting reflector surface for dentsChecking LNB housing and weather sealsTesting LNB arm rigidity and alignmentEvaluating bolts, nuts, and clamp tightnessDeciding when replacement is requiredLesson 9Electrical safety and grounding checks: nearby power lines, lightning protection, and bonding requirementsThis section explains recognising electrical hazards near satellite sites, including power lines and masts, common in Nigerian urban areas. Learn grounding, bonding, and lightning protection basics to keep the system and people safe during frequent storms.
Maintaining clearances from overhead linesIdentifying service entrances and metersVerifying dish and mast grounding pathsChecking bonding to building grounding systemAssessing surge and lightning protection
