Flush mounting the antenna

Before drilling holes, it is recommended the antenna be positioned where the location is planned,
cable connected to the GPS Chart Plotter and power turned on to ensure a GPS Fix is received.
1. Remove the threaded base from the antenna dome.
2. To ease installation a flush mounting template for the antenna has been included.
3. Apply the mounting template sticker to the area that was verified for GPS reception.
4. Then, drill out the 0.78" (20mm) and 0.13" (3.2mm) holes, and remove the template.
5. Insert the cable into the 0.78" (20mm) hole and route to the GPS Chart Plotter.
6. Apply a small amount or RTV to the underside of the antenna.
7. Place the antenna and then screw it into place using the screws.
In some cases the screw may not be long enough. If this happens simply apply more RTV to the
underside of the antenna to glue it into place.
