DT-102B
The PROMAX DT-102B Dual DVB-T Modulator is a COFDM modulator compatible with DVB-T standard. This unit includes TS-ASI input and RF output in the UHF band and features fast frequency and output level. The inputs contain services in formats such as SD, HD, MPEG-2, and MPEG-4. The internal combiner delivers a single DVB-T output with high C/N.
