DDF1 30
labeled “ANT1” on the ANTINT board.
5. In the same way connect the wires connected to the DB9 connector
pins 2, 3, and 4 to the “ANT2”, “ANT3” and “ANT4” respectively.
6. Connect the wire from pin 5 on the DB9 connector to the “GND” pad
located near the “ANT4 IN” connection on the ANTINT board.
7. Verify that you have connected the control cable wires correctly. If
they are not connected properly your DDF1 will not indicate the right di-
rection of the elusive transmitter you are trying to find.
8. Connect the coax cables from the 4 antenna assemblies to the “ANT1
IN”, “ANT2 IN”, “ANT3 IN” and “ANT4 IN” connection points using the
same procedure in steps 4 through 8 on page 28.
Congratulations, You have finished the major assembly of your DDF1. All
that is left to do is some testing and then we’ll have you put it in the case and
weatherproof your antenna assembly. Don’t get impatient and jump ahead.
If there is a problem you may need to disassemble something if you go to the
final assembly now.
