The A3LA-RS modem uses a single SMA female 50-ohm connector to both transmit and receive
(see Figure 2).

Cable loss between the modem and the antenna is critical and must be kept less than 3 dB at
the operating frequency of 1616 to 1626.5 MHz. The minimum link margin of 13.1 dB must also
be maintained. NAL Research offers several types of antennas for use with the A3LA-RS
modem. For low cost and applications where small form factor and light weight are required,
NAL Research recommends model SYN7391-C see Figure 3 .
