Digi Connect Wi-EM Antennae
The Digi Connect Wi-EM is available with dual-diversity antenna connectors. The right
antenna (P2) is always used for transmit and receive.The left antenna is receive only. The
antenna will choose the best signal (pin vs. socket). The Digi Connect Wi-EM always has
two antenna connectors but using the second antenna is optional.
The antennae are connected to the module with reverse polarity SMA connectors (sub-
miniature size A). The antennae fit the connectors on the module only one way to ensure a
proper connection. The antennae function best when placed perpendicular to each other
(one straight, the other up or down) to prevent interference from each other.
