DTV-UDWG series wideband digital TV repeaters can transmit one or more DTV
signals to cover the buildings, basements, and signal shadow area effectively, etc.
Repeater includes the main function modules and additional function modules.
The main function module of the repeater above 1 watts power types, consists of
pre-amplifier module, power amplifier module, power module and water-proof air
cooling systems (50 watts above types). Through continuous design optimization,
CEKE has integrated the pre-amplifier module, power module and power amplifier
module into one component, greatly increasing the reliability and stability of the
equipments.
