Notes:
• The XL-GPS requires a 12 Volt-compatible antenna. Antennas not rated for 12 V
will be damaged.
• Use an antenna splitter to connect a single antenna to multiple receivers. Don’t use a
BNC “T” connector.
• The L1 GPS antenna is designed to operate with up to 150 ft. (60.96 m) of RG-59
coax cable. An optional Down Converter can be used for cable runs of 1,500 ft.
(457.2 m) using RG-58 coaxial cable.
