VHF
VHF Digial Active DAS
Model: 03321D
Product Details
RF Direct Sampling: The signal is digitized without down-conversion, preserving signal integrity and enabling wideband digital processing.
Cavity Filter: Superior out‑of‑band rejection, minimizing interference and ensuring clean, stable signal amplification.
NMS facilitates remote/local control and monitoring.
SNMP Support: Higher cyber security and convenient data collection.
Stable and improved signal transmission quality.
1 MU (Master Unit) can support up to 32 RU (Remote Unit) to maximize utilization of fiber optic cable
