How to Align a Satellite Dish After Physical Installation
Bolting the dish to the wall is the easy half. Aligning it — pointing it precisely at a satellite 36,000 km away — is the skill that separates a working system from a frustrating one. Done methodically, even a first-timer can get a rock-solid lock.
Prep: Know the Numbers
Open a satellite pointer app and note the azimuth (left-right), elevation (up-down) and LNB skew for your chosen satellite. Have a known transponder frequency, symbol rate and polarisation ready on your receiver, or simply select a channel that should be there.
Set Elevation Roughly First
Loosen the elevation bolts and tilt the dish to the angle shown on the app. Most dishes have an elevation scale marked on the arm — set it within a degree or two. Tighten finger-tight.
Set Azimuth by Compass
Use a compass or the phone's compass to swing the dish to the correct left-right angle. Remember to correct for magnetic declination — the app does this for you if you give it permission to use GPS.
Use a Signal Meter
Disconnect the receiver from the LNB cable and plug in a cheap satellite finder between them. Power on the receiver. As you sweep the dish left and right, the meter will jump and beep when it crosses a satellite. Sweep slowly — the satellite is narrow, and it is easy to swing past.
Peak Both Strength and Quality
Once the meter jumps, stop and look at the receiver's signal screen. You will see two bars: strength and quality. Strength will already be high; quality will be low. Now nudge the dish in tiny increments — millimetres, not centimetres — in every direction until quality peaks. This is the real alignment.
Fine-Tune LNB Skew
Rotate the LNB in its holder slightly while watching the quality bar. Peak it. Then re-check the dish peak — skew and dish angle interact, so alternate between the two two or three times.
Lock It Down
When quality holds at 85% or more, gently nip up the bolts. Do not tighten one bolt all the way — tighten them in sequence a half-turn at a time, re-checking the signal after each.
Final Test
Run a scan. If you get the expected channels, tap the dish gently to simulate wind and re-check the quality. If it stays put, you are done.
Alignment is patience, not strength. The satellite does not care how tight your bolts are — it cares about fractions of a degree. Slow down, watch the meter, and let the quality bar guide your hands.
