Definition: Studio to transmitter link refers to the audio/video signal transmission link or the point-to-point microwave link for transmitting digital TV programs (ASI or IP format). Radio stations using studio transmitter links usually also have a transmitter / Transmitter Studio Link (TSL) to return telemetry information. In short, a studio transmitter link is a point-to-point broadcasting process, which can connect a studio with other radio transmitters or TV transmitters of a TV station.
When the audio and video signals of a radio station or TV station are first recorded by the equipment in the radio studio, and then sent out from the radio studio or TV station by the radio transmitter, generally these audio and video signals will realize the transmission function of the studio to transmitter link through the following three ways:
- Use of terrestrial microwave links
- Use optical fiber
- Use a telecommunication connection (usually at the transmitter site)
Studio to transmitter links can be divided into analog Studio Transmitter Link, digital Studio Transmitter Link (DSTL), and hybrid Studio Transmitter Link. If you want to transmit high-quality audio signals over a short distance, it is necessary to learn some of these types of studio transmitter links.
- Digital Studio Transmitter Link and analog Studio Transmitter Link
Digital studio transmission link, also known as digital Studio Transmitter Link (DSTL), is a way to select network transmission mode for point-to-point audio and video signal transmission. The general digital studio is composed of excellent audio and video encoder, transcoder, Studio Transmitter Link bridge, and feeder, visit for more.

This Digital Studio Transmitter Link Equipment 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 ultra-low-cost and ultra-long signal transmission distance.
Digital studio to transmitter link equipment is always in these places: radio stations and TV stations that need to set up and use PTP FM / TV antenna for long-distance transmission
Compared with digital Studio Transmitter Link, analog Studio Transmitter Link has stronger anti-interference and anti-noise functions. High-quality radio equipment often appears in the form of packages. For analog Studio Transmitter Link, an STL transmitter, STL receiver, STL antenna, and some accessories are essential.
Generally, an STL antenna is a Yagi antenna that can be used for vertical and horizontal polarization. This antenna provides great directivity. It is a high-quality and low-cost antenna. Generally, it is made of stainless steel clamp. The excellent Yagi antenna has the characteristics of remarkable radio ease of use, high gain, lightweight, and high weather resistance.

- Traditional Microwave Studio Transmitter Link System and Special Studio Transmitter Link System
The traditional microwave link system is favored by many operators of large radio or television stations because it has a very stable signal transmission capacity. The general traditional microwave link system consists of two Paraboloid Antennas, an STL transmitter and STL receiver, and some feeders, but these seemingly simple broadcasting devices can easily realize stable audio signal transmission for 50 miles (80 kilometers).
However, there is a link system that is different from the previous three Studio Transmitter Links. FMUSER-Studio Transmitter Link is a non-traditional Studio Transmitter Link system from FMUSER broadcasting.

Generally, the bandwidth of broadcast Studio Transmitter Link bandwidth is measured in GHz, that is, the number of transmitted programs can be large, and the audio and video quality is also very good. This is why the Studio Transmitter Link link is also called UHF link radio
An STL antenna is usually an essential part of the studio transmitter link equipment used for transmitting audio and video signals from the studio. Studio Transmitter Link antennas are the ideal solution to ensure continuous transmission between the studio and the transmission center, they are usually made of aluminum. These link antennas cover a series of VHF and UHF frequencies. The common coverage frequencies are 170-240 MHz, 230-470 MHz, 300-360 MHz, 400 / 512 MHz, 530 MHz, 790-9610 MHz, 2.4 GHz, etc.
Analog studio transmitter links such as microwave studio transmitter links and ordinary studio transmitter links, their Studio Transmitter Link Frequency Range is 8GHz - 24GHz and 200/300 / 400MHz, respectively; and digital studio transmit links such as Digital Studio Transmitter Link and Mobile Audio Link, their Studio Transmitter Link Frequency Range is 4.8GHz - 6.1GHz and 1880-1900 MHz, 2320-2370 MHz, 2575-2635 MHz, 2300-2320 MHz, 2555-2575 MHz, 2370-2390 MHz, 2635-2655, respectively MHZ. Of course, the corresponding price of simulated Studio Transmitter Link is expansive, but if there is a sufficient budget, simulated Studio Transmitter Link is a well-deserved choice.

Q: What licensed microwave bands are typically used?
Above 40GHz is allowed in the USA. According to FCC - click to visit, 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 (See Millimeter Wave 70-80-90 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, FMUSER suggests you checking the licensed radio spectrum band in your country in case any personally illegal broadcast happens.
