View of the modulator
It is high class, dual side band modulator of Lithuanian firm Terra (made in EC). Due to high output level (100dB), it is applicable in non-professional head stations. Of course, it is possible to combine several pieces (e.g. 8, with FV-8 R60108 splitter). The modulator allows operation in B/D/I/L/M/N standards. It can provide reception in even 30 outlets. The high output level of the modulator permits omitting additional stages of signal amplification.
