FU-518A Analog TV Modulator PAL NTSC SECAM For Television Transmitter

This Modulator is one digital-type analog TV modulator developed by software technology. The built-in new FPGA + DDS technology architecture is used to achieve full-system, full-channel, digital, and analog TV modulation functions. The technical indicators fully meet and exceed the relevant national standards.
The whole machine is produced using the full SMT process, which not only has outstanding technical indicators, but also has high product reliability.
Functionally flexible design. With adjustable power ratio of image and sound; no video protection and other functions.
The whole machine uses a 1U / 19-inch standard aluminum alloy chassis, which is small and lightweight.
This modulator is the best choice for the modulator of TV transmitters of various power levels.
● Adopting the new FPGA + DDS technology architecture to realize digital modulation, superior performance and good consistency.
● Adopt modular design concept, which is convenient for long-term maintenance and upgrade.
● With no-video protection function and lightning protection measures for the whole machine and components.
● Various technical parameters can be read through the front LCD screen.
● With RS232, TCP / IP and other communication interfaces, and for remote monitoring and management.
● Using high-quality switching power supply, complete protection functions, wide voltage range operation.

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
