User's Manual Part 2

Slide the rubber boot over the PL259 connector; if desired, it may be filled with

silicone grease for a better weatherproof seal.

Screw the antenna down into the antenna mounting adapter.

Ensure that the mounting adapter is connected to ground. If necessary, connect a

grounding wire, 2.5 mm

minimum, to a suitable ground point.

Installation of the antenna cable

Start routing the antenna cable at the antenna end.

Where the cable passes through bulkheads or decks, waterproof deck glands

should be installed. Securely fasten the cable against vibration using plastic cable

tie wraps.

Complete routing of the antenna cable at the NAV-7 TNC connector.

Fitting the TNC connector

A TNC connector is supplied as part of the NAV-7 Receiver Kit.

Fit the TNC connector as shown below:

• Place the rubber boot, gland nut, washer and rubber seal onto cable.

Remove the outer insulation for a distance of 8mm.

• Slide the cable braid sleeve over the screen braid, fold the braid back and

trim off extra braid.

• Strip 2.5mm of the inner insulation to expose the centre conductor.

• Solder the pin onto the centre conductor.

• Assemble the connector and tighten the gland nut. Push the rubber boot

securely over the gland nut.
