9.5 GPS Antennas and Cables
The antenna that a receiver uses to collect satellite signals is
sometimes called a GPS antenna to distinguish it from a radio antenna.
Radio antennas are used for communication between receivers and
external networks or systems.
Note To use older models of antennas, such as the Choke Ring or
Micro-Centered L1/L2 antennas, with a 5700 receiver, you need to use
an antenna power adapter and an external power source for the
antenna. For more information, see Antennas, page 43.
Connect the 5700 receiver to its GPS antenna using the yellow TNC
connector. Use a coaxial cable with a right-angle TNC plug at the
antenna end.
If the antenna cable length is use
up to 15 meters (45 feet) RG-58 cable
up to 30 meters (100 feet) RG-214 cable
over 30 meters (100 feet) one of the following:
in-line amplifier
semi-rigid coaxial cable
a low-loss cable assembly
