DDF1 29
Locate the 4 antennas, 5 plastic caps, 4 lock washers, 4 M3 kepnuts, 4 M3
screws 4 antenna boards and 1 antenna switch board.. Refer to the follow-
ing diagram and perform the following steps on each of the 4 antenna
mounting boards.
Final Antenna Board Assembly
Use the picture on Page 30 as a guide to construct the antenna.
1. Insert an M3 screw through the center hole from the back of the an-
tenna board.
2. Place a #4 internal tooth wash over the screw.
3. Screw one of the M3 kep nuts, (that’s one of the nuts with a lock
washer attached to it), onto the screw so the lock washer is facing away
from the board and tighten it.
4. Remove the protective paper on a flexible magnet and attach the
magnet to the bottom of the antenna board. We suggest you not trim the
magnet since doing so will decrease the ability of the assembly to stay
put on a magnetic surface. (BIGGER IS BETTER (-: )
5. Screw a whip antenna onto the M3 screw.
6. Make a small notch to fit over the coax on the bottom edge of the
plastic cap. You can use a sharp hobby knife, side cutters or a hot tool
such as your soldering iron. Melting with iron will be smelly… use your
ingenuity here.
7. Slide a plastic cap down over the antenna and align the small cutout
you made over the coax. This is a tight fit but I’m sure you can do it.
8. Repeat the above steps for each of the other 3 antenna assemblies..
Final ANTINT Board Assembly
In order to install the control cable between the antenna ANTINT board and
the DDF1 controller you will need a cable with at least 5 conductors
. A
length of CAT5 LAN cable or any other cable with at least 5 conductors is
acceptable. It is not necessary to have twisted pairs or shielding but a cable
that is fairly small in diameter and flexible is probably best. It is IMPOR-
TANT that the connections between the DB9 connector and ANTINT board
be made in the correct sequence or your DDF1 will not function properly.
1. Determine the length of control cable you require and cut your cable
to this length.
2. If your cable has only 5 conductors you may skip to the next step
NOW
. If you are using a cable with more than 5 conductors, identify and
isolate 5 matching conductors on each end of the cable.
3. Refer to the DB9 diagram on page 30 and solder one each of the 5
wires in the cable to pins 1, 2, 3, 4 and 5. It is important you know which
wire is connected to which pin so you can connected them to the
ANTINT board in the next steps.
4. Connect the wire connected to pin 1 of the DB9 connector to the pad
