Installation/User Guide 23
External GPS Antenna (Optional)
External antennas are generally only necessary if the V4 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).
The suggested installation point is the centerline of the vehicle roof, with minimal cable run
to prevent wind and car wash damage. Ensure that there is a clear antenna view of the open
sky, and maintain a minimum of 6 inches from any rooftop edge or ledge. See below.
Drill, deburr, grommet, weather seal, and cable thru hole as required. Drill hole size - 1/2”
(.500”); grommet size - 3/8” (.375”).
Optional
GPS Antenna Adhesive Tag (for non-magnetic mounting
surfaces)
Whenever possible, avoid installing adhesive in cold, wet, or damp conditions. Ideal
application range is: 70˚F to 100˚F (21˚C to 38˚C).
1. Clean and dry the surface prior to placement to obtain optimum adhesion. The best
surface cleaning solvent is an isopropyl alcohol/water mixture (rubbing alcohol).
2. Remove the backing from the peel and stick to the surface.
