The first completely legal licence free digital audio link in Europe: STAT/STAR1800


  • Completely legal
  • Complete free to use
  • No notification
  • Distance range and wave propagation identical to 1500MHz band
  • Perfect digital audio quality
  • Limited audio delay
  • Easy and quick installation with low cost coax cable
  • Optional internal stereo and RDS coder (MPX output)
The used frequency band is 1795 to 1800 MHz and is completely free to use with 20mW EIRP, according to the harmonized European Standard for wireless audio devices EN 301 357.
The STAT/STAR1800 system is 100% compliant with this standard (see document). The standard is implemented in most European countries. (see FAQ list).


How is it possible to reach such a large distance (33km) with so little power (20mW)?
Because digital audio is combined with techniques only used in satellite links (see FAQ list).

We designed this innovative STL because there are too much disadvantages with the present generation of STLs:

1500MHz (Belgium): licence required and yearly fee (+-1600 euros), too noisy sometimes.
869MHz (Belgium): illegal, is now being confiscated by BIPT.
10GHz (Belgium & The Netherlands): expensive equipment, licensed, yearly fee, only line of sight.
2.4GHz & 5.8GHz WiFi: illegal because the antennas mustn't be changed and may not be put in a mast.
Internet/IP: cheap equipment, subscription money, long audio delay, reliability? (internet dropouts).
