With the AMB1981 dipole-antenna and the AMB1982 monopole-antenna with magnet foot and
1.5m antenna cable AMBER offers ideal solutions for the 868 MHz frequency range (SMA m).

Monopole antennas such as the AMB1982 need a ground plane at the feeding point
with a minimum radius of about Lambda/ 4. The lack of a ground plane reduces the RF
range.
13.4 Recommendations for mechanical manufacturing
Use only vacuum packed components for reflow processing
Depending on the used parts the limits in J-STD-020 may not be exceeded
Recommendations for the temperature curve of the solder oven cannot be made
because this depends on the main PCB, the quantity and properties of the components
and the solder paste used.
