Installation at Remote Location
1.
Bolt the F AS-1-4 R to the angle bracket using
the four screws, nuts and washers as shown in
Figure 1.
2.
Referring to Figures 2 and 3, 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 control cable is indicated
in Table 1.
3.
Using the U-bolt and Mast Clamp supplied,
mount the FAS-l -4R on the tower or support
mast (mast diameter must be 37-6 4 mm, or
different hardware will be required).
4.
Mate the connectors, one at a time, with their
jacks on the F AS-1-4 R, applying sealing
compound around each mated fitting after
the weather sleeve has been slid over the
connector (Figure 4).
NOTE: Use short feeder lengths of 50-ohm coaxial
cable to connect the antenna feedpoints
to the FAS-l -4R. The antenna feedpoints
should be unbalanced (using baluns, if
necessary), and as close as possible to
SO-ohms at the intended operating fre
quencies for best results.
Interconnection with the FC-7 5 7 AT
Connect the main coaxial feedline from the INPUT
jack on the F AS-1-4 R to the ANT B terminal on
the FC-757AT, and connect the wire ends of the
4-conductor cable from the REMOTE jack on the
FAS-l -4R to the REMOTE terminal strip on the
FC-757AT, as indicated in Table 1.
