FAS. I-4R REMOTE
The FAS-I4R Remote Antenna Selector may be
installed either at the feedpoints of the antennas
or inside the FC-I02 Antenna Tuner, providing
selection between up to four antennas. Alterna-
tively, the FAS-l-4R can be installed altd operated
independently from the FC-|02 when a l2 VDC
power source and switching nreans are provided.
Ileavy duty relays are used to enable good isolation
at RF power levels up to 1.2 kW PEP.
Installation in the FC-102
|. Remove the subpanel on the rear of the
FC-102 as shown in Figure l.
Insert the FAS-l4R module into the FC-102,
and install the four nrounting screws as shown
in Figure 2.
Using the short coaxial junrper and 4-con-
ductor intercorurection cable. cotrtrect the
ANT B terminal on the frc-102 to the INI'UT
coaxial tertninal on the FAS- I -4R, and
connect the wire ends oI the 4-coltductor
cable to the terrninal strip ott tlte FC-102,
securing the other end o[ this cable into the
REMOTE jack on the FAS-I4R as sltowtt irt
Figure 3. Connect tlte antenna feedlines to
jacks I through 4 on the FAS-l-4R.

Irrstallation at Remote Location
l. Bolt the FAS-I4R to the angle bracket using
the four screws, nuts and washers as shown in
Figure 4.
Referring to Figures 5 and 6, cut the small
end of each weather sleeve to the correct size
to provide a tight fit around the cables being
used - one for each coax and one for the
control cable. Then slide the sleeves over the
cables and solder the wires to the connectors.
The wiring of the 4-pin connector is indicated
in Table | (previous paCe).
Using the U-bolt and Mast Clamp supplied,
mount the FAS-l-4R on the tower or support
mast (mast diameter must be 37 -64 mm, or
different hardware wll be required).
Mate the connectors, one at a time, with their
jacks on the FAS-14R, applying sealing
compound around each mated fitting after
the weather sleeve has been slid over the
connector (Figure 7).
NOTE: Use short feederlengths of 5O-ohm coaxial
cable to connect the antenna feedpoints
to the FAS-I4R. The antenna feedpoints
should be unbalanced (using baluns, if
necessary), and as close as possible to
5O-ohms at the intended operating
frequencies for best results.
See page 4 for interconnection instructions.

Interconnection without FC-l 02
l. When 12 V DC at 100 mA is provided, along
with a lP4T switch, the FAS-I4R can be
operated either at the station or a remote
location. Refer to Table 2 and Figure 9 for
the required interconnections.

Connect the FAS-I4R to the FC-102 as
described in step 3 of "Installation in the
FC-102" and shown in Figure 3, using the
interconnecting coaxial cable as the feedline,
and cutting or extending the 4-conductor
control cable as necessary.
