Lesson 1Line-of-sight analysis: spotting trees, buildings, roof edges, and seasonal bush impactLearn to check line-of-sight by identifying trees, buildings, roof edges, and other blockages. You will consider the satellite arc, possible dish positions, and changes in bush growth during seasons that could impact signal quality over time in Namibian landscapes.
Using sighting tools to follow satellite pathsSpotting current physical blockagesEstimating bush growth effects seasonallyComparing other spots for dish mountingNoting LOS risks in site recordsLesson 2Pre-work check: paperwork, permits, customer confirmation, and site photos for baseline recordsBefore starting, confirm all paperwork, permits, and customer details. This part explains verifying the job scope, taking initial photos, and noting any existing damage or dangers to protect both the technician and the client in line with Namibian standards.
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 terminationsThis section looks at checking coaxial cables, connectors, splitters, and multiswitches for damage, moisture, and signal loss. You will also review indoor connections, labelling, and support to ensure reliability over time in dusty or humid Namibian conditions.
Identifying kinks, crushing, and sun damageChecking connectors for rust and loosenessEvaluating splitter and multiswitch positionsInspecting indoor wall plates and terminationsLabelling cable paths for future serviceLesson 4Using tools and apps for initial azimuth/elevation/skew lookup (satellite lookup sites, compass apps)Learn to use satellite lookup websites and mobile apps to get azimuth, elevation, and skew values. This covers aligning maps, magnetic versus true north, and confirming readings with on-site conditions, adjusted for Namibian locations.
Choosing reliable satellite lookup websitesUsing compass and inclinometer appsUnderstanding magnetic vs true northChecking skew values for selected satellitesCross-checking app data with field conditionsLesson 5Visual check of dish, mount, mast, and wall/roof bracketsDo a thorough visual check of the dish, mount, mast, and brackets. Learn to spot misalignment, loose fittings, rust, and water damage that could affect safety, aiming accuracy, or system stability in Namibian weather.
Checking dish alignment and visible warpingInspecting mast straightness and strengthExamining wall and roof bracket fixingsIdentifying rust, cracks, and metal fatigueAssessing sealant and water entry pointsLesson 6Personal protective gear and PPE checklist: harnesses, anchors, helmets, gloves, and bootsUnderstand required personal protective equipment for satellite work, including harnesses, anchors, helmets, gloves, and boots. Learn to use a PPE checklist to check condition, fit, and compliance before each job in rugged Namibian sites.
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 risks, and rescue plansPlan safe access to roofs and balconies by selecting stable ladder spots, managing fall risks, and preparing rescue options. Learn to assess surfaces, anchor points, weather dangers, and local rules before climbing in Namibian terrains.
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 strengthAssess the reflector, feedhorn or LNB, and all fasteners. This covers corrosion, sun damage, water entry, and structural weaknesses that may need repair, replacement, or re-securing in harsh Namibian environments.
Inspecting reflector surface for dentsChecking LNB housing and weather sealsTesting LNB arm strength and alignmentEvaluating bolts, nuts, and clamp tightnessDeciding when replacement is requiredLesson 9Electrical safety and grounding checks: nearby power lines, lightning protection, and bonding needsThis explains recognising electrical hazards near satellite sites, including power lines and service masts. Learn grounding, bonding, and lightning protection basics to keep the system and people safe in Namibia's stormy conditions.
