Zonar V3, Руководство пользователя и инструкция по установке, Страница: 14 / 28

External GPS Antenna (Optional)
1) External antennas are generally only necessary if the V3™
GPS unit is enclosed in a radio signal interfering area (e.g.
metallic box, under seats, on dashboards with flat windshields,
and in cabs or cockpits constructed primarily from metallic
material).
2) Follow all General Guidelines as specified on page 7.
3) May be magnetically mounted or mounted via optional aluminum
plate and screw for non-magnetic surfaces, see Fig. 14-2.
4) Suggested installation point - centerline of vehicle roof, minimize
cable run to prevent wind and carwash damage.
5) Ensure a clear antenna view of the open sky.
6) Maintain a minimum of 6 inches from any rooftop edge or
ledge, see Fig. 14-1.
7) Drill, deburr, grommet, weather seal, cable thru hole as required.
Drill hole size - 1/2” (.500”); grommet size - 3/8” (.375”).
Note : For optimal system performance Zonar recommends rooftop
mounting with a clear view of the sky.
