MAKING COAX CABLES - Page 1 of

Making proper fittings on the ends of a coax cable is an art. Take a bit of time to understand the steps involved in making the perfect connection.
Please advance to the next page...
The Galileo systems uses High Grade Beldin 1694A Coax Cable. The spool supplied only has 300 feet on it, so if your cable run is longer, you will need to order more cable from Ground Control.
Max cable run is 300 feet from the IDU to the Satellite Dish.
Cut off one end of the coax cable with wire cutters.
Locate the coax splicer and place the coax inside of the splicer.
Note where the red arrow shows the coax end is flush with the V notch of the coax splicer.
Place a finger in the hole of the coax splicer and twirl the splicer around the cable 4 or 5 times...making complete circles.
Pull the splicer away from the cable (without opening the splicer) so that you remove a segment of coax shielding. In fact, you have made 2 cuts at the same time.
- Cuts just the outer jacket of the coax.
- Cuts all but the center copper line.
If you are having trouble making the perfect cut on your cables, the razor blades inside of the splicer are adjustable. Use the Allen Wrench (3) to adjust the blade heights (1 & 2).
Note here the Allen Wrench in one of the blade height adjustment screws.
Fold back the wire shielding over the outer jacket as shown. Make sure the white plastic shielding that covers the copper wire is free of debris that may short out the connection.
Locate a snap connector.
Snap out the blue fitting on the connector and slip it over the coax cable.
Twist the connector onto the coax cable.
So that the white plastic shielding comes is flush with the base of the connector as shown. Take a mental snapshot of this picture to remind you how far to twist on a connector.
Cut off any excess of the connector so that it is between 2 and 3 millimeters long.
Slide the blue fitting to the connector and "Snap" it into the connector.
The connector is now ready to be placed into the coax crimping tool.
