The thread used on the antenna is an industry standard (1inch 14TPI) used on a wide range
of mounting brackets.
The antenna cable can be cut and spliced to ease installation. Care must be taken when
reconnecting the antenna cable to protect from water and corrosion.
2.3.0
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 0.31" (8mm) and 0.13" (3.2mm) holes, and remove the template.
5. Insert the cable into the 0.31" (8mm) hole and route to the GPS Chart Plotter.
6. Apply a small amount or RTV to the under side 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.
