Terrestrial Digital TV Wide Frequency Band Repeaters (50W)

No.

Features

1

Wild-type waterproof design, simple and attractive appearance, suitable for outdoor work.

2

Support all standard digital TV, mobile TV signal transmission and Signal complement point, support single spectrum and wide-band (multi-spectral) amplification.

3

Patented RF delay technology. Avoid the interference with multi-point signal cross-coverage.

4

Large range for AGC control circuit (50dB), high-precision ALC compensation function, ensures the output power stability when external signal large changes.

5

Complete protection functions: self-excitation protection, overload protection, signal fast impact protection, power protection, temperature control protection, password security control.

6

Microcomputer control, support remote debugging and monitoring after equipped with communication module (GPRS).

7

Equipment Customization: optical input type, microwave input type, single frequency network delay adjustable.

8

Equipped with high precision ALC supplementary function, can work stably even big change has been made to the environment.
