• TX1_P → SMA F-F Adapter → RX1_P
• TX1_N → SMA F-F Adapter → RX1_N
• TX2_P → SMA F-F Adapter → RX2_P
• TX2_N → SMA F-F Adapter → RX2_N
• TX3_P → SMA F-F Adapter → RX3_P
• TX3_N → SMA F-F Adapter → RX3_N
• TX4_P → SMA F-F Adapter → RX4_P
• TX4_N → SMA F-F Adapter → RX4_N
• TX5_P → SMA F-F Adapter → RX5_P
• TX5_N → SMA F-F Adapter → RX5_N
• TX6_P → SMA F-F Adapter → RX6_P
• TX6_N → SMA F-F Adapter → RX6_N
• TX7_P → SMA F-F Adapter → RX7_P
• TX7_N → SMA F-F Adapter → RX7_N
To ensure good connectivity, it is recommended that the adapters be secured with a wrench,
Note:
however do not over-tighten the SMA connectors.
