FREQUENTLY APPLICABLE USES:
1). Community Radio stations
2). LPFM radio stations
3). City radio stations
4). Christian Church radio stations
1) OVERHEAT PROTECTION:
The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range.
2) OVER SWR PROTECTION:
SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile.
3) FAN ERROR ALARM
When the fan stopped running, there will be alarming message showing on the screen like the following:
4) FREQUENCY AUTO MATCHING:
The 1kw FM transmitter auto scans the best matching frequency on antenna to maximize the broadcasting efficiency at minimum SWR ratio, this ensures the best performance from both the transmitter and antenna.
5) MODULATION ADJUSTABLE:
When audio mixers are connected with the 1kw FM transmitter through the XLR Balanced audio input interface, the transmitter will provide plenty of options for the modulation to best match with the mixer.
6) ONE TOUCH OPERATION:
This FSN-1000T 1kw FM transmitter is designed with a precisely sensitive touch screen in replace of the control buttons on previous transmitters. With all information displayed clearly on the screen, users can control and configure all parameters very easily.
7) FLEXIBLE AUDIO OPTIONS
The pre-emphasis of 1kw FM transmitter are flexible to choose among 0US / 50US/ 75US, users can choose the best match mode according to their own needs.
8) ADJUSTABLE POWER OUTPUT
The RF out of this 350W FM transmitter is continuously adjustable from 0-350 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w…50w…350w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs.

Now widely used in: 2G/3G cell phone coverage hotels, schools, hotels, railway stations, docks, office buildings, factories, residential quarters and other areas with wlan / wifi signal coverage, various wireless intercom system, short wavelength radio waves various ham frequencies are supported!
The cable supports:
The frequency 0-12G
Note: 1/2 what does it mean?
Is the outer diameter of the metallic shield of the feeder units of inches, regardless of the inner core and coaxial .1 / 2 refers to the outer diameter of the metal shield is 1.27 cm feeder 7/8 refers to the feeder outer diameter of the metallic shield is 2.22 cm, the outer insulation is not including.
Depending on the wireless transmission of electromagnetic waves in the frequency in the feeder, the attenuation of the signal intensity is different. For example: the electromagnetic frequency: 890 — 920M, attenuation at 1/2 feeder is: 7.5 – 7 .7dB/100 meters. 7/8 feeder attenuation of approximately: 4.2 – 4 .5/100 meters.
