"RP-SMA connectors were introduced to separate professional and commercially available equipment, preventing unintentional or intentional connection of high-gain professional antennas with SMA connectors and commercial wireless equipment with RP-SMA connectors, violating federal or international laws. Today, however, both type of connectors are readily available. RP-SMA connectors are widely used by Wi-Fi equipment manufacturers to comply with specific local regulations {Section 15.203 Antenna requirement}, e.g., the FCC, which were intended to make it difficult for consumers to connect antennas with gain and thereby breach compliance. However, RP-SMA equipped antennas are now widely available." -- http://en.wikipedia.org/wiki/SMA_connector
Openmoko only supplies 3V to GPS. Novatel antenna wants 4.5V to 18V so we had to use a splitter.
