View of the modulator
High quality, dual side band modulator of Lithuanian Terra company (made in EU). Due to high output level (100dBμV), it is applicable in non-professional head stations. It is possible to combine several modulators (e.g. 8, with FV-8 R60108 splitter). The modulator allows operation in B/D/I/L/M/N standards. It can provide reception of the modulated channel even in 30 outlets. The high output level of the modulator permits to omit additional stages of amplification.
