better performance. The AN190 is shipped with 50 feet of coaxial cable
and an external splitter.
The AN200 is an AN190 with 20 feet of RG-59U coaxial cable. The AN200
is shipped as standard equipment with the Northstar 8901 sensor).

The length of coaxial cable to the combo antenna must be a minimum of
20 feet, but not more than 100 feet. Coil up any unused length of cable;
do not cut it to less than 20 feet! Be sure that all cable connectors are
securely fastened, and that the cable itself isn't subject to any tight bends.
For land-based applications, mount the AN190 near the top of the vehi-
cle, where a clear and unobstructed view of the horizon is available in all
directions.
For marine applications, mount the AN190 low on the vessel to avoid
extra motion from pitching and rolling. Be sure to install the AN190 lower
than high-power transmitting antennas, such as radar or satcom.
The Northstar AN195 H-Field antenna is a low-profile, high-performance
DGPS antenna that can be used in place of the 8410 four-foot whip
antenna; its small size is ideal for applications that require minimal over-
head clearances.
The AN195 is housed in the same waterproof body as the AN190
"combo" antenna, but contains only the circuitry for receiving differential
GPS corrections.
