Required Antenna Separation
The antennas from any transceiver of the BreadCrumb ES1 may not be co-located with the antennas of
any other transceiver. The co-location restriction is satisfied by maintaining 20 cm separation between
the antennas of different tranceivers. There is no restriction for the separation between the antennas
from the same transceiver, but testing at installation is recommended to verify the system performance
that is achieved with a specific antenna deployment.
