The BreadCrumb LX4 provides up to four Type N female antenna connectors. One connector is
located on the front side of the enclosure (see Figure 3), the other three connectors are located on
the back side of the enclosure (see Figure 4). There are many different LX4 Models available, each
with a different configuration of radios and antennas. Each antenna connector will be labeled with
the frequency of its corresponding radio.

disconnect external antennas with the power to the BreadCrumb LX4 off.
