1. Higher information density.

2. More precise resolution.

3. Describe as close as possible to the true value of physical quantities in nature.

4. Analog signal processing is simpler than digital signal processing.

1. Low price, moderate cost, suitable for low to medium budget.

2. Strong anti-interference ability, no noise accumulation.

3. Especially suitable for long-distance high-quality transmission.

4. Easy to encrypt processing, strong security, and high confidentiality.

5. Easy to store, process, and exchange.

6. The equipment is more miniature, easy to integrate.

7. Occupies a wider channel frequency band.
1. The cost is very high, so the product is very expensive.

2. The signal diffraction ability is very poor and easily obstructed by the terrain.

3. It is susceptible to noise, and the effect becomes more significant with increasing distance.

4. The noise effect will make the signal lossy and difficult to be restored, and the noise will be amplified.

1. Increase the complexity of the system, it requires an analog interface and a more complex digital system.

2. The frequency range of the application is limited, mainly due to the limitation of the sampling frequency of A/D conversion.

3. The power consumption of the system is relatively large. The digital signal processing system integrates hundreds of thousands or more transistors, while the analog signal processing system uses a large number of passive devices such as resistors, capacitors, and inductors. This contradiction will become more prominent as the complexity of the system increases.

STL Link - How They Work

According to Wikipedia, studio to transmitter link refers to an audio/video signals transmission link, normally speaking, an STL link is more like a point to point STL broadcast process that can link one studio with the other radio transmitters or TV transmitters in the TV station.Generally, the transmission function of STL link can be realized in the following three ways:

● Using terrestrial microwave links
● Using fiber optic
● Using telecommunication connection(usually on the transmitter site)

FMUSER STL-10 Studio Transmitter Link. More

In the classification of Studio To Transmitter Link, there is a DSTL system that is often called "studio transmitter link over IP". This is a POINT TO POINT system that can convert analog audio and video signals into digital audio and video signals and finally convert them back into the first stage and this is achieved through multi-channel encoders such as multi-channel encoder and decoders (16 channels for example), click here to view the latest information of FMUSER Digital Studio Transmitter Link system.

What is in the Studio To Transmitter Link System?

However, the type of STL link system is not limited to DSTL (digital STL link). Common studio to transmitter link equipment usually includes the following three kinds of transmtiters link equipment: STL link transmitter, STL link receiver and STl antenna, while the commonly used STL link equipment in the broadcasting industry has the following three types

STL-10 studio transmitter link transmitter - STL transmitters
STL-10 studio transmitter link receiver - STL receiver
● Yagi antenna (STL link supporting) - STL antenna

STL link transmits audio and video signals from radio studios (the transmitting carrier are usually STL transmitters) to another location such as other radio studio/radio stations/TV station or other uplink facilities (the receiving carrier is usually a STL receiver).

Usually the bandwidth of broadcast STL bandwidth is measured in gHz, that is to say, the number of programs transmitted can be very large, and the audio and video quality is great, and that's why the STL link is also alled as UHF link radio

All About FMUSER's Studio To Transmitter Link Equipment

RF Broadcast
RF broadcast is good in terms of product quality with quite complete FM products. Other products, such as AM radio, IP and TV, are good. But, some studio to transmitter link equipment lacks the necessary classification and is not very competitive in price.

The product page of Broadcastcomponents is very well done. Many FM broadcast products are clear at a glance, but some studio-to-transmitter link equipment lacks the necessary classification, and there is no obvious STL link price and STL link product parameters marked.

Scmsinc's STL link products are expensive. For low budget buyers, it's not a good choice to buy studio to transmitter link equipment from scmsinc. However, you can browse some STL link models and product parameters on the modified webpage, so that you can better judge which transmitter links you really need


Bswusa's STL link products are very complex, and the price is not cheap. The price of a single STL transmitter is more than one to two times that of the broadcast STL transmitter package on the market. For low budget buyers, it is not a good choice to buy studio to transmitter equipment from bwusa, but you can browse some STL products on the website Link model and product parameters, so that you can better judge which transmitter links you really need

Q: How to broadcast high-quality audio and video from a long-distance?

Choose the right broadcast system set is important. We recommend two systems for you. 

● STL-10 studio to transmitter link. 
● FMUSER Digital studio to transmitter link. 

The first one is the analog STL link, while the second one is the digital STL link, they both have pros and cons, but they are the best choices for the low-budget buyers who want to transmit point to point (PTP) high-quality audio and video signals

Q: What licensed microwave bands are typically used?
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 (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 follow this principle, FMUSER suggests you checking the licensed radio spectrum band in your country in case any personally illegal broadcast happen.

Q: Long-distance short wave radio broadcasting use which kind of wave?
We know that the use of a short wave long-distance radio is to broadcast music and voice to shortwave, this can be used in military radar, diplomatic communication. Its further uses include two-way international communication for a hobby, education, and emergency service, as well as for long-distance aviation and marine communication. 

In long-distance short wave broadcasting, shortwave bands can be reflected or refracted from the ionosphere which is defined as a layer of electrically charged atoms in the atmosphere called. Due to the path of this wave from the ionosphere, they are called the ionospheric waves. Thus, we can say that long-distance short-wave radio broadcasting uses ionospheric waves
