Titanium Satellite C-Band LNBF C138 Performance Plus
The Titanium Satellite C138 Performance Plus LNBF is designed for C-band reception with emphasis on interference mitigation. It features a 5G, 4G, RADAR, and WiFi interference elimination filter in an export model configuration. The RED band pass filter targets the 3800-4200 MHz range, focusing on blocking 5G N78 and N77 low bands while noting limitations with N77 high band usage in some regions. Suitable for installations requiring strict filtering to preserve C-band signal quality, this model is part of Titanium Satellite’s Performance Plus line.
Titanium Satellite C-Band LNBF C238 Performance Plus
The C238 model mirrors the C138’s interference-focused approach with the same export model limitations. It uses a RED 3800-4200 MHz band pass filter aimed at suppressing 5G/4G and radar signals to improve C-band signal integrity. This option is positioned for professionals who need strong interference control in dense RF environments, with emphasis on filtering specific 5G bands while acknowledging regional variations in 5G deployment.
C-Band LNBF C140-5g Blue Interference Filter
The C140-5g Blue is a BLUE band pass filter covering 4000-4200 MHz with emphasis on filtering 5G bands for N78 and N77 High and Low bands. It provides a single output with voltage polarity switching. By design, it supports a broader high-band filtering approach, which can help minimize interference from newer 5G deployments while maintaining stable C-band reception.
C-Band LNBF C240-5g Blue Interference Filter
The C240-5g Blue model features a BLUE 4000-4200 MHz band pass filter with two outputs. It is designed for filtering 5G bands across N77 & N78 low and high bands and supports two independent outputs with isolated polarity switching. This makes it suitable for setups requiring dual-path distribution without shared interference paths.
Norsat C-Band LNB 5100RF
The Norsat 5100RF is a C-Band LNB option with a frequency range of 3.70–4.20 GHz and stability specification around +/-100 kHz. It represents a traditional approach to C-band reception without explicit emphasis on 5G interference filtering, suitable for environments where RF interference is manageable or where other filtering stages are employed elsewhere in the system.
Buying Guide: Key Considerations for C-Band LNBFs
- Interference filtering strategy: RED (5G/4G/RADAR) vs BLUE filters address different parts of the spectrum. Consider your region’s 5G deployment and the bands that need attenuation.
- Band coverage and outputs: 3800-4200 MHz RED filters versus 4000-4200 MHz BLUE filters; number of outputs and polarity switching may affect dish layout and signal routing.
- Export model implications: Some export variants are not suitable for certain markets due to regulatory or RF considerations. Verify compatibility with your region’s standards before purchase.
- Frequency stability: LNBs like the Norsat 5100RF list stability specs (e.g., +/-100 kHz). Stability influences tuning accuracy and long-term performance.
- Single vs dual outputs: Dual-output LNBFs offer greater flexibility for multi-tuner setups, but may require additional hardware to manage polarity or signal distribution.
- Brand and support: Reputable brands with documented performance and accessible support can simplify installation and troubleshooting.
- Installation environment: Outdoor-rated hardware, weather sealing, and mounting options affect reliability in harsh climates.
- Compatibility with existing dishes and receivers: Ensure the LNBF’s connector standards and IF output match your satellite system components.
When selecting a C-band LNBF, factor in regional 5G uses, the need for dual outputs, and whether you prefer RED-only or BLUE-inclusive filtering. The five models above provide a mix of interference-focused options and traditional stability-focused LNBs to accommodate diverse installation scenarios.
