Chapter 2 - Installation
2.7 Connecting Antennas
The cabinet assembly provides external access to the male N-type connectors for
your external antennas. Your antenna cable should terminate with a 90° N-type
female connector or an N-type female to male elbow adapter may be used for a
more convenient connection to the cabinet. Insertion loss for the elbow type of
connector is typically between 0.1 and 0.2 dBm.
The antenna cabling for the Micro BTS can be configured in several ways
depending on a number of factors including the number of TRXs, number of
antennas and use of diversity. Your site specific configuration was determined
during the network planning stage of implementation.
In the subsequent sections, each RF configuration is detailed from the RF module
connector to the internal RF connector. Figure 2-21 illustrates the relationship
between the three connectors. The RF modules are connected to the internal RF
connectors at the factory and are pre-configured for your Micro BTS
configuration.
You will attach an elbow connector and your antenna cable to the external RF
connector associated with the internal RF connector shown in the appropriate
figure.
