Technical data TDH - TV converter modules
TV channel converter modules in the TDH range is converting any TV channel in the
VHF and UHF band to another frequency. For optimized function and performance in
handling analogue or digital signals, two different versions are available.
Wide-range automatic gain control (AGC) secures right level into the distribution net
High modulation error rate (MER) valued by means of SAW filter technology,
secures best possible signal quality
Full-range conversion
DC supply for preamplifier
