UHF Indoor Wide-band Frequency Terrestrial Digital TV Transmitter(CKUB-T800)

Innovative broadband adjacent channel transmitting technology, Greatly reduce terrestrial digital TV transmission system invest

Wide-band Frequency Transmission Network Technology is an innovative technology using one Wide-band frequency transmitter to achieve multi-channel transmitting, solving the existing problems of single-channel system in one fell swoop. It is conducive to build up the terrestrial digital TV multi-channel single frequency network with effective coverage and strong stability.

With this innovative technology, our one set of transmitter can transmit multiple TV channels, breaking through the limitation that the traditional transmitter only can do the single channel transmitting, which makes the investment in digital TV system significantly reduced, and our transmitter also do not need to use the high power synthesizer, realizing the adjacent channel transmitting, it dramatically increase the utilization of wireless frequency resource, and the transmitting frequency can be modified at any time in the transmitting process. since we just need one set of transmitter to build the network, the later stage energy consumption and the operation cost will be dramatically reduced. Building the network with only one transmitter, it is relatively simple than the traditional networking method, it can effectively reduce the failure rate; this will effectively reduce the maintenance cost. Because our transmitter have reduced the power combiner insertion loss, this will increase the effective power of the transmitter, therefore, under the equal transmitting power, our Wide-band frequency  transmitter can cover more large area than the traditional single-channel transmitter, achieve the goal that covering the large area with low power.
