FMUSER STL10  Studio to Transmitter Link for FM Radio Station

Background Information:

 A studio-transmitter link (or STL) sends a radio station’s or television station’s audio and video from the broadcast studio to a radio transmitter or television transmitter in another location.

Features

*Synthesized from 220 to 260MHz, 300 to 320MHz, 320 to 340MHz,400 to 420MHz and 450 to 490MHz
*The transmitted and received frequency can be easily set by digital front panel
*Suitable for digital audio. The subsonic over modulation and the low frequency phase distortion are controlled by a feedback circuit in order to exalt the audio quality of the latest digital systems.
*Low THD distortion: the THD value with stereo or mono demodulated and deemphasized signals is negligible.
*Flat frequency response: due to the latest generation technology and the components precision the flatness of frequency response is absolute.
*Low noise: the excellent signal to noise ratio either in mono or in stereo allows the use of this STL¡¯s in multi-hops networks without decreasing the audio quality.
*High sensitivity: it allows to reduce the STL’s antennas investment.
*Great RF immunity: allows to operate in most hostile RF environments.
*High adjacent channel rejection: obtained thanks to the excellent mechanical shielding and the precision of RF filtering.
*High frequency stability with the internal temperature compensated crystal reference.
* Integrated LCD Display: complete diagnostic and measurement front panel LCD displays.
*Integrated information display and protection controls: for all transmit parameter and protection for malfunction.

This is often necessary because the best locations for an antenna are on top of a mountain, where a much shorter tower is required, but where a studio is completely impractical. Even in flat regions, the center of the station’s allowed coverage area may not be near the studio location or within a populated area where a transmitter would be frowned upon by the community, so the antenna must be placed several miles or kilometres away.

Depending on the locations that must be connected, a station may choose either a point to point (PTP) link on another special radio frequency, or a newer all-digital wired link via a dedicated T1 or E1 (or larger-capacity) line. Radio links can also be digital, or the older analog type, or a hybrid of the two. Even on older all-analog systems, multiple audio and data channels can be sent using subcarriers.

STL10 Studio to Transmitter Link / Inter-city Relay is a VHF / UHF FM communications system providing a high quality broadcast audio channel with variety optional bands.These systems offer greater rejection of interference, superior noise performance, much lower channel cross-talk, and greater redundancy than currently available composite STL systems.

How far(long) the transmitter cover? The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far. EXAMPLE 5W FM Transmitter use in the city and hometown: I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile). I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile). I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft). Below are the approximate range of different power FM Transmitters. ( The range is diameter ) 0.1W ~ 5W FM Transmitter ：100M ~1KM 5W ~15W FM Ttransmitter : 1KM ~ 3KM 15W ~ 80W FM Transmitter : 3KM ~10KM 80W ~500W FM Transmitter : 10KM ~30KM 500W ~1000W FM Transmitter : 30KM ~ 50KM 1KW ~ 2KW FM Transmitter : 50KM ~100KM 2KW ~5KW FM Transmitter : 100KM ~150KM 5KW ~10KW FM Transmitter : 150KM ~200KM How to contact us for the transmitter?
