The SparkFun WRL-09143 is a 900 - 1800 MHz Duck Antenna 2dBi with regular Reverse Polarized -SMA RF connector.
Perfect for use with the XBee 900MHz units. 50 ohm impedance. 105mm long.
The FCC is moving towards Part 15 compliance. All this means is that all the SMA RF connectors are changing gender. Reallyannoying for those of us who need to mate an antenna to an RF device. The FCC gender change was instituted to prevent home users from damaging RF equipment (think home WiFi) when screwing on an antenna. If all antennas are female, there is no way to damage the center connector. However, you have to be very sure now what kind of SMA connector you need.
