antenna tuner (matchbox) for achieving resonance and min. SWR anywhere
within the covered frequency bands.
NOTE: Some automatic antenna tuners in transceivers do not have the
impedance range to tune the Model DX-CC on bands other than the covered
ranges. An external wide range tuner may be required.
INSTALLATION INSTRUCTIONS
Unroll the DX-CC wire elements, removing any kinks that may have been
induced during the packing operation. At each side of the center insulator you will
find 3 wires:
A 80/40 15 meter wire with an ISO-RES coil and 6 stand-off insulators installed.
(Approximately 41 ft. long)
B. 20 meter wire. (Approximately 16ft. long)
C. 10 meter wire. (Approximately 8 ft. long)
With the antenna wires laid out on the ground in a fully extended condition, run
the 20 and 10-meter wires through the stand-offs as shown in FIG. 2 with the 20
meter wire running through the center holes of the 3 long stand-offs and through
the bottom holes of the 3 short stand-offs. The end of the 20-meter wire should
be twisted back on itself around the last stand-off for proper support, after being
made taut. The 10-meter wire is run through the bottom holes on the 3 long
stand-offs as shown. It is then twisted back on itself around the last long stand-
off, after being made taut. All of the stand-offs should be spaced equally along
the wires for best support. When all of the wires and stand-offs have been
positioned properly, tightly wrap wire-ties around the top and bottom of each
stand-off and antenna wire to prevent movement. See FIG. 2 for method. For the
wire-ties, cut approx. 6" lengths from the 12-ft. coil of wire provided. Choose the
arrangement for mounting your new DX-CC, (inverted vee, flat top dipole, etc.). If
the inverted form is chosen cut a short length of the supplied rope to each end
insulator of the DX-CC. Tie the remaining two pieces of rope to each end
insulator of the DX-CC. Any 50-ohm coaxial cable may be employed for use with
the DX-CC. We suggest the use of RG-213 as it is generally a good "buy" and
will last many years. Installations where only low power operation is being used
can get by with RG-58A/U or RG-8X type coax. If the inverted vee configuration
is to be used, try to arrange the ends of your DX-CC so that when viewed from
the side the angle at the apex of the antenna is 90 degrees between the two
element wires – see Figure No. 1.
