The BreadCrumb LX3 provides three Type N female antenna connectors. The connector located on
the front side of the enclosure (see F in Figure 3) interfaces to the 2.4 GHz antenna. The connector
located on the the back side of the enclosure, on opposite corner of the front side antenna (see B in
Figure 4), interfaces to the 900 MHz or 5 GHz antenna depending on the BreadCrumb LX3 model.
Finally, the remaining connector on the back side of the enclosure (see A in Figure 4) interfaces to
the 2.4 GHz or 5 GHz antenna depending on the BreadCrumb LX3 model.

Because the antennas are mounted top and bottom and on opposite corners of the unit, the only
viable means of using the LX/LX3 with all antennas attached is by using the pole mount option.
Care should be taken to make sure the pole is mounted plumb (or possibly carefully tilted to account
for altitude differences) for reasons noted below:
•
The 802.11a 5 GHz Vertically Polarized Omni antenna (OD5WM-6) has an extremely
narrow coverage plane. It only extends 5 degrees above and below the center-line, even at
relatively short range. This means that two units using these antennas will have to be at the
same altitude with the antennas plumb to see each other.
•
The 802.11g 2.4 GHz Vertically Polarized Omni antenna (OD24M-7) covers a more lenient
18 degrees above and below center at distance and an even wider range up close. Therefore,
it is much more forgiving of imperfect placement than the 802.11a antenna.
Warning
To avoid possible damage to the BreadCrumb radio(s), always connect or
disconnect external antennas with the power to the BreadCrumb LX/LX3 off.
