GG-24M 24 in 1 Headend Fixed channel catv modulator
Short Description:
GG-24M 24 in 1 Headend Fixed channel catv modulator
The GG-24M is a 4RU rack mounted chassis that allows for installation of up to 16 pieces microprocessor-controlled fixed or agile mini-modulators. Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level.
All modulators are perfect factory set to desired channels and proper offset.
FEATURES
1. Switching power supply for installation flexibility and precise voltage regulation
2. Two cooling fans for long life performance
3. 45dBmV chassis output level, no need extra combiner
4. SAW (surface acoustic wave) filtering on IF for superior in band C/N
5. Front panel access controls enables easy setup
