These STLs use two long range 900MHz, 2.4GHz or 5GHz active panels of a few hundred milli watts with 16 to 20dBi antennas, this is ample power to get the studio to transmitter signal 10km and more. The link is a digital stream, each panel is connected to a Barix codec to provide analogue audio in and out.

The panels use the latest OFDM modulation which is very robust even a low signal levels with interference. The Barix codecs encode and decode the stereo analogue audio into the robust mp3 digital stream. At the receiver end of the link the audio is so good, no noise, no distortion, nothing, it’s sounds like it’s connected directly by cable to the mixer in the studio.

You install the STL antenna panel on the same tower as the FM antennas, if possible underneath the FM antennas as low down as possible. You don’t need a separate tower. It is important that the STL antenna panel at the studio can see the STL panel antenna at the FM tower, this is a “LINE OF SIGHT” system for 5GHz and 2.4GHz and “NEARLY LINE OF SIGHT” for 900MHz. It does not matter how low the STL panel is on the FM tower as long as it can see the studio STL panel.
