Core Advantages
- High Isolation & Low Loss: Ensures ≥40dB separation between bands to prevent cross-interference, while the ultra-low 0.42dB insertion loss preserves signal strength at the cell edge.
- DC/AISG 2.0 Transparency: Supports DC/AISG bypass (up to 40V/3A), allowing remote control of Smart Antennas and RET systems directly through the combiner.
- Rugged Outdoor Deployment: Rated IP67 for superior protection against dust and heavy rain, suitable for both pole and wall mounting in harsh environments.
- PIM-Optimized Design: Engineered with -155dBc PIM stability to maintain the highest Signal-to-Noise Ratio (SNR) for high-speed 4G/5G data services.
- Future-Proof Connectivity: Uses 4.3-10 Female connectors, providing the mechanical reliability and electrical stability required for next-generation telecommunications infrastructure.

FAQ
- Q: How does this combiner simplify tower-top installations?
- By combining the 1920-2170MHz and 2300-2690MHz bands into a single feeder cable, this unit reduces the number of cables running down the tower. This lowers wind load, decreases site rental costs, and simplifies overall system maintenance.
- Q: What is the benefit of the DC/AISG bypass feature?
- The bypass allows power and control signals (AISG) to flow from the Base Station (BTS) to the Remote Electrical Tilt (RET) motor in the antenna. You won’t need separate power cables for your antenna’s tilt adjustment, as the combiner is fully “transparent” to these control signals.
- Q: Is 40dB isolation sufficient for 2.1GHz and 2.6GHz co-location?
- Yes, 40dB is a professional-grade isolation level that ensures the high-power signal from one band does not desensitize the receiver of the other. It maintains clean signal paths for both frequency ranges, even when operating at the maximum 300W power load.
- Q: Can this unit be used in coastal or high-humidity areas?
- Absolutely. With an IP67 waterproof rating and a wide operating temperature range (-20°C to +60°C), the combiner is fully sealed against moisture and salt air, making it reliable for coastal sites and humid tropical climates.
