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.

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?
