Using SatPointer for Astra 2E Dish Alignment at 28.2°E
Astra 2E sits in geostationary orbit at 28.2° E, so a dish intended to receive it needs an azimuth, elevation and, where relevant, LNB skew calculated from the installation address. Those values are not universal: they change with latitude, longitude and site elevation, making a location-aware pointing tool more dependable than copying a bearing from a European forum.

SatPointer is a free web-based application operated by TotalSat Limited. It combines Google Maps, satellite orbital data and a selected location to produce pointing directions for reception, uplink, downlink and mobile satellite links. Its database also presents beam coverage and estimated dish-size information. For Australians, it provides a useful extra check: whether Astra 2E is above the horizon at all, rather than simply whether a dish can be pointed roughly north.

Understand the 28.2°E orbital position
Orbital longitude is measured east from Greenwich, not from an Australian time zone. A geostationary satellite therefore has one fixed position, while every dish needs its own solution. From most Australian mainland locations, including Sydney, Melbourne, Brisbane, Adelaide, Hobart and Perth, Astra 2E at 28.2° E lies below the visible horizon because of the angle between the location and orbital position.

This geometric limit is easy to miss. A forum post may call 28.2° E “east”, creating an impression that the satellite should be in an eastern sky; the practical bearing can be very different, and here it may point below the horizon altogether. SatPointer calculates the result from the selected map position instead of relying on that shorthand.
Australian external territories require separate treatment. Cocos (Keeling) Islands and Christmas Island have different longitudes from the mainland and may offer a positive elevation, though line of sight still does not guarantee reception. SatPointer’s [Yamal satellite guide] demonstrates the same orbital-position method for another regional broadcasting market.
Compare the available alignment methods
A practical comparison separates calculation, confirmation and physical installation:
| Method | Main input | Result | Coverage check | Best use |
|---|---|---|---|---|
| SatPointer | Address or map point | Azimuth, elevation and possible skew | Beam and estimated dish size | Planning before installation |
| Signal meter | Dish and receiver | Signal strength and quality | Usually requires a known feed | Final tuning |
| Compass and chart | Manual bearings | Approximate position | Not normally included | Backup or learning |
| Professional installer | Site survey | Measured alignment and setup | Can verify reception | Complex or inaccessible mounts |
SatPointer is strongest at the planning stage. It narrows the search to a calculated direction and can flag a satellite that is below the horizon or outside the expected footprint. A meter is strongest at the final stage because it measures the actual carrier arriving at the receiver.
The methods complement rather than replace one another. A precise digital calculation can still be defeated by a magnetic compass error, a shifted mast or an obstructed line of sight, while a meter cannot rescue a dish aimed at a target that is not visible.
Enter the installation location
Use SatPointer’s Google Maps-based location control to select the property where the dish will be mounted. Search for the street address, then adjust the pin to the building rather than leaving it on a suburb centroid. In Australian everyday speech, you might tell someone to “drop a pin on the house”; for dish alignment, that pin needs to represent the actual installation position.
Site elevation also matters because it changes the elevation angle slightly and affects the surrounding horizon. Check the marker against the roof or wall position and, where possible, enter the ground elevation reported for the site. A city-level location can be enough for an initial check, but it is not suitable for final fine-tuning.
After selecting Astra 2E at 28.2° E, review the elevation before focusing on azimuth. For a mainland Australian address, a result below the horizon is a warning that this orbital position cannot provide a direct dish solution from that site. Satellite details and the estimated dish size can help with planning wherever the target is genuinely visible.
Convert the pointing values into dish adjustments
Azimuth is the horizontal direction measured clockwise from true north, while elevation is the angle above the true horizon. Treat SatPointer’s azimuth as a geographic bearing rather than reading it directly from a magnetic compass; Australian magnetic variation differs by location and can introduce a meaningful error. LNB skew, where shown, is the rotation applied to the feed arm for the chosen polarisation.
An offset-fed dish can look slightly down when its boresight is correctly aimed, so the calculated values should be applied to the dish’s signal axis rather than judged by the front plate alone. Mark the mast position, set the dish to the stated elevation and then rotate it to the azimuth. A second person at the receiver can make small adjustments while watching signal strength.
The same geometry supports specialist installations. SatPointer’s [DIRECTV commercial guide] shows how pointing calculations are applied to another geostationary satellite family. For Astra 2E from Australia, however, these adjustments are relevant only if the displayed elevation is positive and the receiver can actually see the appropriate beam.
Verify coverage before tuning the receiver
Visibility and reception are separate tests. Astra 2E is associated with the European broadcasting market, and an Australian observer must not assume that its downlink footprint reaches the Australian mainland. Beam maps show where a particular transmission is designed to be received, whereas the pointing solution only describes where the satellite appears in the sky.
The local television market reinforces that distinction. Australian pay-TV and regional free-to-air services generally rely on Optus and Foxtel infrastructure rather than Astra’s European feeds. An Astra 2E channel may reach Australia through redistribution or a specialist receiving system, but it would not normally form part of the standard local lineup.
Use the database coverage information, then confirm the transponder frequency, polarisation, symbol rate, encryption status and receiver support with the provider. SatPointer’s [Anik satellite guide] illustrates how orbital position and regional coverage vary across another satellite family. If geometry and coverage both check out, use the receiver meter for final adjustment; if either fails, changing dish alignment will not solve the underlying problem.
Match the equipment to Australian conditions
SatPointer’s estimated dish size is a planning guide, not a guarantee. Ku-band reception can use a relatively small offset dish, while C-band feeds and demanding links generally need more gain and often a larger reflector. A high-quality feed, clean connections and correct LNB polarisation can affect the practical result as much as the nominal dish diameter.
Australian sites add their own demands. A mount on a colourbond roof needs a fixing method suited to profiled metal, while tiles, timber and masonry each require different anchors. Coastal salt, strong ultraviolet sunlight, summer heat and sudden squalls can shorten cable or mount life. Perth’s dry summers and Darwin’s humid, salt-laden air are different maintenance environments. Both demand hardware suited to local conditions rather than underspecified components.
Safety is part of the calculation. Roof access, power lines, wall height and safe mast anchoring can determine whether an installation is practical. Use the pointing data alongside a proper mounting plan and signal check rather than treating the app as permission to climb or improvise a rooftop installation.
Put the result into a repeatable workflow
A reliable process begins with location, continues through visibility and coverage checks, and ends with measured signal quality. SatPointer supports this workflow for reception, uplink, downlink and mobile links, making the same approach useful when documenting an installation or helping a remote user reproduce a setup. Further reading is also available through the YouLinks resource hub.
The service also offers a customizable widget for websites, blogs and forums. An installer, club or community site can present the relevant satellite and location tools without asking every reader to navigate the full interface. The widget is especially useful for Australian DIY communities where accurate diagrams and shared coordinates save repeated troubleshooting.
Open SatPointer, enter the installation’s exact address, select Astra 2E at 28.2° E, and check the elevation and coverage before ordering or adjusting equipment. If the satellite is above the horizon and coverage confirms the feed is available, apply the generated azimuth and elevation, set any specified LNB skew, and confirm the result with a receiver meter. Share the SatPointer widget when you want visitors to check the same pointing information for themselves.
