4. How FMUSER ADSTL Works?

1) 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) 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.

5. Common Highlights of FMUSER ADSTL

Although with such a budget price, its excellent performance is still comparable to hundreds of thousands of dollars of the same level of digital studio transmitter link and analog studio transmitter link:

3. Q: How do broadcasters link the studio to the transmitter?

A: You should first have a studio transmitter link and better contact radio station experts such as FMUSER.

Let's say that there is a broadcast group that bought ADSTL from FMUSER, and here is how studio to transmitter link will be working: once the studio transmitter link is ready-steady, the studio will send the audio and video to the transmitting antenna tower, with the signals transmitted by the STL link transmitter and the Yagi antenna, and finally be received by the studio transmitter link receiver and another Yagi.

4. Q: Where to borrow a radio station studio transmitter link system from?

A: FMUSER may be one of your best radio station equipment suppliers.

The microwave STL link system is very expensive among all radio studio transmitter links, so many broadcasters will choose to borrow a used studio transmitter link. Obviously, to buy studio transmitter link ADSTL from FMUSER equals almost the same price as renting a microwave-type STL link system. Maybe you need no longer need to pay for the extra studio to transmitter link system price of renting, instead, asking for the latest quotation of ADSTL seems to be a better choice. If you need more spec on ADSTL (pictures, videos, and instructions are free to use), leave your message, we will reply to you as soon as possible.

5. Q: What is the studio to transmitter link price?

A: Prices range from a thousand USD to ten few more thousand USD or even more, depending on brands. 

The prices vary from studio transmitter link manufacturers and types of studio to transmitter link equipment. If you have enough budget, you can consider buying from Rohde & Schwarz. The price is about $1.3W. If the budget is not enough and still has a need for high-quality audio and video transmission, you can consider buying an affordable studio transmitter link from FMUSER. It takes only 3k-5k USD for a complete system with everything included (e.g., STL transmitter, STL receiver, antenna, and accessories)

6. Q: Which licensed microwave bands are usually used?

A: Above 40GHz is allowed in the USA.

According to FCC, early technology limited the operations of these systems to radio spectrum in the 1 GHz range; but due to improvements in solid-state technology, commercial systems are transmitting in ranges up to 90 GHz. In recognition of these changes, the Commission adopted rules allowing the use of spectrum above 40 GHz.

This spectrum offers a variety of possibilities, such as use in, among other things, short-range, high-capacity wireless systems that support educational and medical applications, wireless access to libraries, or other information databases. 

However, not every country follows this principle. It is recommended to have a check on the licensed radio bands in your country to prevent any personal illegal broadcasting. FMSUER provides a variety of frequencies for the studio to transmitter link so that you are no longer limited by the special permission of the local radio administrations. The frequency bands provided by FMSUER include 100MHz-1000MHz, 433-860MHz, 2.3-2.6g, 4.9-6.1g, 5.8G, 7g-9g.

7. Q: How to find out if the studio transmitter link is licensed or not?

A: Turn to an RF expert such as FMUSER for help or consult local radio administration.

Before using or buying studio transmitter link equipment of any species, make sure you have contacted the local radio and TV administration to apply for available qualification certificates or provide corresponding procedures as required. Our expert RF team will assist you handling in the subsequent matters of obtaining an STL link system license - the whole process from equipment assembly to the 100% safe system operation
