Garmin GMR 20 Antenna
Radar
Description :
New Garmin GMR 20 2KW Antenna Radar Maximum
range: 24 nm Package includes: GMR 20 radar unit Mount hardware kit Power/marine
network cable (15 meters) Cable grommet Installation manual The GMR 20 (2kW
radome) features a narrow 3.6-degree horizontal and 25-degree vertical
beamwidth, which delivers accurate target acquisition and better penetration
through rain and fog. It has a range of 24 nautical miles (nm). For fast and
efficient presentation of radar signatures, raw data is processed within the
radome and presented on Garmin’s GPSMAP® 3006C and GPSMAP 3010C
chartplotter/multifunction displays (MFDs).The GMR 20 features automatic and
manual sensitivity and tuning controls, including gain, sea clutter, and rain
clutter—which allows boaters to spend less time tuning the unit and more time
navigating. The unit also boasts selectable interference rejection, which
mitigates the effect of nearby radar transmissions.Once the GMR 20 is interfaced
with a GPSMAP 3006/3010 MFD, it is possible to overlay radar images on the
charting to help reconcile radar signatures with known objects. Users can view
"radar only" or split the display for multiple views of radar and charting. To
aid in collision avoidance, the unit also offers Mini Automatic Radar Plotting
Aid (MARPA) capability, which allows boaters to track the bearing, course, speed
and predicted closest approach (by both time and distance) of up to 10 targets.
MARPA functionality requires GPSMAP 3006/3010 MFDs and an optional heading
sensor.*
