A composite LNB enables a ?single satellite dish? to simultaneously receive ?C-band and Ku-band signals? from the same satellite. While most commercial or DIY composite LNBs suffer from ?signal attenuation (1–2 dB)?, the PBI Turbo-4200-CK10 is engineered for precision. This发烧级 (high-precision) LNB delivers reliable signal integrity and is tailored for scenarios requiring dual-band reception with one antenna.

?Technical Specifications?

?Parameter?	?C-Band?	?Ku-Band?
?LO Frequency?	5.15 GHz	9.75 GHz / 10.60 GHz (Dual LO)
?Input Frequency?	3.4–4.2 GHz	10.7–12.75 GHz
?Output IF?	950–2150 MHz	950–2150 MHz
?Noise Figure?	≤15 K (Typ.)	≤0.7 dB (Typ.)

?Key Advantages?

?Integrated Dual-Band Design:
- Eliminates the need for multiple antennas/dishes, reducing deployment costs by ?30–40%?.
?Precision Engineering:
- Factory-calibrated alignment surpasses DIY modifications, minimizing ?signal loss? and ?phase distortion.
?Dual LO Flexibility (Ku-Band)?:
- ?9.75 GHz LO: Optimized for linear polarization (V/H) satellites.
- ?10.60 GHz LO: Supports universal/wideband reception (e.g., SES, Intelsat).
?Cross-Band Interference Rejection:
- Built-in ?**≥25 dB isolation**? between C/Ku bands prevents signal crosstalk.
