Amplifiers and signal splitters are installed in specialized cabinets located at floor technical axes and appropriate locations on the ground according to design drawings with power supply lines for amplifiers. Use RG RG and QR cables to transmit signals and use splitters and branches at technical axes to ensure the signal level at every TV point is uniform and ensures ensure signal quality.
Technical requirements of MATVCATV system The image and sound quality at the sockets is good no shadow or interference meeting television standards specifically The television signal output level at TV installation points reaches dBV. No interference between channels. SN signalnoise level is guaranteed to be dBV. Channel width at least Mhz for PAL DK system and Mhz for NTSC system. The output signal at the antenna is usually adjusted to dB uV. This signal level when passing through the cable network system will be gradually attenuated by the splitter. Graphics Design Service this signal to reach the same level before dividing it to the sockets. Normally an amplifier is usually responsible for amplifying TV points. . Some basic concepts The basic principle of MATV system design is to ensure that the image and sound quality at all sockets are good without shadow or noise.
Specifically the output signal level at all points The TV must be within the allowable range dB. If the signal level is the image quality is unsatisfactory if the signal level is the image will be distorted. Television signals are transmitted from the antenna through the cable network system splitters tape and to TV points. This signal will be attenuated when passing through the cable network and above devices and amplified by an amplifier the attenuation will be proportional to the frequency used of the transmission channel. Here we calculate the maximum attenuation at Mhz frequency specifically as follows .. Attenuation.
