5. How FMUSER ADSTL Works?


1) How to use the Yagi Antenna as the STL antenna?

Generally, the STL antenna is a Yagi antenna in the studio transmitter link system, which can be used for vertical and horizontal polarization, providing good directivity. Excellent Yagi antenna usually has the characteristics of excellent radio ease of use, high gain, lightweight, high quality, low cost, and weather resistance.

In this affordable studio to transmitter link package, two Yagi antennas are included as STL antennas, they will be installed respectively on the broadcasting antenna tower of the studio and the transmitting tower, and will be connected with the STL radio link transmitter (broadcast studio) and the STL radio link receiver (transmitting tower). Meanwhile, two 30-meter long RF antenna feedlines will be connected with the STL transmitter and the STL receiver respectively on the studio tower and transmitting tower and work as a part of the radio studio transmitter link system of HD-SDI audio and video.

2) How to use the STL Transmitter and STL Receiver?

The studio transmits the recorded audio and video through the STL transmitter and Yagi STL radio link antenna and is received by the STL transmitter and STL antenna near the radio engineering room and the transmitting tower.

3) Studio Tower and Transmitting Tower

In a radio studio transmitter link, the STL transmitter will obtain the audio and video signals at the studio end and carry out ultra long-distance transmission (up to 60km) in the frequency range of 100 ~ 1000MHz through the broadcast antenna near the studio (usually Yagi antenna). Then the broadcast antenna installed on the transmitting tower (also Yagi antenna) will receive the audio and video signals from the studio direction

Finally, these high-fidelity audio and video signals will be radiated to your customers by the radio broadcast transmitter and the supporting broadcast antenna.

This digital studio transmitter link has better signal tolerance and lower signal loss in point-to-point audio and video signal transmission. At the same time, it also has the characteristics of ultralow cost and ultra-long signal transmission distance.
