Dish alignment calculators
SatLex Alternative: Dish Calculator Plus Satellite Frequencies
SatLex is a private website about satellite reception, with a copyright notice dating back to 1996. Among other things, it offers an azimuth and elevation calculator that works out where to point a dish from your location.
If you are looking for a SatLex calculator alternative, DishTuner takes a slightly different approach: the dish alignment calculator sits next to satellite frequency charts and channel pages, so you can find a channel, see which satellite carries it and get the pointing angles for your location in one place.
What SatLex Does Well
- A detailed azimuth and elevation calculator: besides azimuth, elevation and LNB tilt (skew) it shows the offset angle, the distance to the satellite, the signal delay and the angles for a motorised (polar) mount.
- Specialist calculators for installers, such as the elevation of an obstacle, the f/D ratio, antenna efficiency, beam width and noise figure.
- Reference pages on LNB types, antenna types, DiSEqC and multi-receiver dish configurations.
- Calculator results have their own URLs, so a result can be shared, and the site is available in many European languages.
SatLex and DishTuner Compared
| Feature | SatLex | DishTuner |
|---|---|---|
| Azimuth, elevation and LNB skew | ✔ | ✔ |
| Choosing your location | City list or latitude/longitude | Search, tap on a map or use GPS |
| Offset angle, distance, signal delay, motor angles | ✔ | — |
| Obstacle, f/D, efficiency and beam width calculators | ✔ | — |
| CSV export | Satellites visible from your location | Each satellite's transponder frequencies |
| Satellite frequency charts | — | ✔ satellite pages |
| Channel pages with tuning details | — | ✔ channel directory |
| Languages | German, English and other European languages | English, plus the calculator in Persian, Arabic, Urdu and Hindi |
| Mobile app with compass and AR pointing | — | ✔ free Android app |
— means DishTuner does not offer the feature, or we could not find it on SatLex's public English pages (checked from archived copies, 2024–2026), as of November 2026.
When DishTuner Is the Better Fit
- 1. You start from a channel, not a satellite — search the channel directory for its frequency, symbol rate and satellite, then open that satellite's angles.
- 2. You want the frequencies with the angles — each satellite in the satellite directory has its transponder chart, and the calculator links straight to it.
- 3. You are on your phone at the dish — the free Android app adds a live compass and an AR camera view that shows where the satellite is in the sky.
- 4. You prefer Persian, Arabic, Urdu or Hindi — the calculator is available in فارسی, العربية, اردو and हिन्दी.
If you need obstacle, f/D or motor-mount calculations, SatLex remains a good tool for those, and the two sites work well side by side.
SatLex Alternative FAQ
Is DishTuner affiliated with SatLex?
No. DishTuner is an independent project and is not affiliated with or endorsed by SatLex. SatLex is a trademark of its owner.
Does DishTuner calculate LNB skew like the SatLex calculator?
Yes — pick your location on the map and a satellite, and DishTuner shows the azimuth, the elevation and the LNB skew, and tells you whether the satellite is above your horizon.
Can I see a satellite's frequencies next to its pointing angles?
Yes — once you have set your location and picked a satellite, the calculator links to that satellite's DishTuner page, which lists the transponder frequencies, polarisation, symbol rates and channels, with a CSV download of the frequencies.
Is DishTuner free?
Yes — the calculator, the satellite frequency charts and the channel pages are free with no signup, and the Android app is free to download (ad-supported, with optional paid upgrades).
