3.1.8 Antennas
165 nanoBTS units provide SMA connectors that are exposed when the antennas are
unscrewed as illustrated in Figure 5. (The removable antennas for 165C, 165D, 165G and
165H are shown in Figure 5. The removable antennas for 165A and 165B are smaller.
165E and 165F have no removable antennas.)

The 139/140 series is normally used with its own internal antennas, of which there is one
for transmit and one for receive. The units can be supplied with an optional external
antenna kit, which allows the unit to be connected to an external duplexer, booster system,
distributed antenna system or other external radio system (not supplied by ip.access). See
[INST_300] for more details on the external antenna kit.
Figure 6 shows the 139/140 unit with external antenna kit fitted.
The external antenna kit introduces negligible loss, so the transmitter and receiver
specifications given in sections 3.2.5, 3.2.6 and 3.2.7 apply equally at the external antenna
ports.
