CEKE Brand 1000W UHF Transmitter For Digital TV
CKUB-T800
Product Introduction
A. Optimized products indicators, meet the requirement of Wide Frequency Band transmission, reduce investment,save energy to decrease operation cost.
C. Compatible for 4 different Wide Frequency Band transmission standard :
ATSC (USA) / DVB (Europe) /ISDB (Japan) / DTMB (China)
Main Features
1) 470--862MHz broadband response and low noise design.
2) Design of low power consumption and linearization advances emitting power of the transmitter reduces nonlinear distortion.
3) Very low group delay feature, suitable for digital signal transmission.
4) ALC keeps output of constant power, output VSWR detecting protection.
5) Apply to single-channel or multi-channel UHF digital television transmission system.
6) Be used in the broadband repeating of HFC, AML, or MMDS digital TV signal.
7) Realize wireless network coverage of digital TV at a low cost.
8) Modular design simplifies installation, field services and upgrade.
9) Automatic and manual switching backup systems available.
10) Build-in lightning protector with current-dividing series power prevents lighting surge and
instant overvoltage.
11) Local monitoring and control.
12) Wireless remote monitoring and control (Optional).
