2.1.8 POD-H-DTM-8x8
Figure 2-30 POD-H-COM-8
2.1.8.1 Functions and features
- Receives downlink signals from up to 8 H-COM. After then, it combines and distributes them to up to 8 H-
HOM.
- Receives uplink signals from up to 8 H-HOM. After then, it combines and distributes them to up to 8 H-COM.
- Combines or distributes VHF, UHF signals
- To minimize negative effects by unused input/output ports such as the degradation of VSWR or isolation
between ports, the unused ports can be switched into 50 ohm termination by user
- Support Monitoring Port(DL path/UL Path)
- When any one sector or DAS system needs low power RU less than 4, H-COM can be connected to H-HOM-
L directly without H-DTM.
 In this case, the attenuator in the common path of H-COM should add 15dB attenuation using web
based GUI to compensate the loss of H-DTM.
2.1.8.2 Specifications
- Frequency range: VHF, UHF, 600~2700MHz
- Maximum RF Power: -25dBm@DL, -15dBm@UL
- Size, weight, and power consumption : refer to Table 2-1
