RFUnderstanding Satellite Finders: Features and Functionality
Advertisement
A satellite finder is essentially a simple satellite signal meter. It’s used to align dish antennas with communication satellites that are in geostationary orbit. These devices are commonly used by satellite dish installers, amateur astronomers, and individuals who want to precisely align their satellite dishes or antennas with specific satellites.
How Satellite Finders Work
Satellite finders work by detecting the radio frequency (RF) signals transmitted by satellites. By measuring the strength of the received signal, users can fine-tune the positioning of their dish or antenna for optimal reception.
Typical Satellite Finder Features
A good satellite finder should offer the following features:
- Ability to edit satellite transponder information, including LO frequency, polarity, and symbol rate.
- Accurate method for antenna alignment and installation.
- Signal strength and quality display.
- Support for DVB-S and DVB-S2 functionalities.
Typical Satellite Finder Front Panel
Figure-1 shows a typical satellite finder front panel. The panel usually contains the following ports/buttons:
- Signal Input (from LNB)
- Signal Output (to receiver)
- DC Input
- UP: Move cursor up
- DOWN: Move cursor down
- LEFT: Move cursor left
- RIGHT: Move cursor right
- OK: Confirm (Enter)
- EXIT: Exit (Cancel)
- Compass
- Buzzer

Keep in mind that there are different models available with unique features. Basic models might only display signal strength, while more advanced ones can also provide information about the satellite’s position, polarization angle, and transponder frequency. Some even have built-in GPS modules to determine your location and the satellite’s position accurately.
