Using an external GPS antenna with an Ashtech MobileMapper or ProMark3 GPS receiver has many advantages. It can provide enhanced signal reception in those areas where the GPS signal is attenuated due to surrounding obstructions. Most external GPS antennas will have an encapsulated preamplifier to boost the satellite signal strength seen by the GPS receiver. If you already have the external GPS antenna or if you plan to buy one, then you will definitely need one of these cables.
