The CUBEX MK II PT 3 and 5 Band QUAD ANTENNA

FOREWORD:

The CUBEX MK II is a pre-tuned Quad Antenna. All elements are factory

measured and under normal conditions should not require adjustment. Elements are designed

for operation in the center of each band. Should one wish to favor the low or high end of one or

more bands, limited "tuning", is provided for at Note 2 at the end of the Instructions. It is

recommended that the assembly Instructions be read completely prior to starting Installation.

Begin antenna assembly by laying one of the "spider" castings on the ground with the

"trough" facing upward. Place the butt ends of four spreader arms in the spider troughs. BE

SURE the arms are all similar (Driven Element or Reflector). Fasten each spreader arm to its

respective casting arm using two "gear" driven clamps on each arm. One clamp is located

near the butt of the arm and is positioned between the two guides on the outer face of the

casting. The other clamp is positioned near the end of the casting arm in the depression

provided for it. The gear driven clamps are assembled and tightened by hand using a

screwdriver. With the screw head facing upward, loop the strap around the arm, positioning

the adjustment screw next to the arm and tighten slightly.

Final permanent tightening should be done at the very end of the wire element assembly after

everything has been positioned properly. The same procedure is followed for the remaining

assemblies.

2. Select the 10 METER DRIVEN ELEMENT, remove only the Twist Ties and carefully uncoil

and gently straighten the element (Use similar technique for all elements). This will permit the

element wire bundle to be laid out straight in preparation for stringing through the spreader

arms.

3. The stringing procedure is illustrated by Figure 3 and there will be less of a tendency to

tangle if this procedure is followed closely.

As the wire element is unfolded, carefully remove the tape and straighten the "bends" enough

to allow passage through the holes drilled in the spreader arms, but try and retain enough of

the kink so that it can later be centered in each respective arm for the purpose of maintaining a

uniformly square structure configuration.

The 10 meter elements are strung through the first set of holes nearest the butt end of the

arms; 12 meter next (optional) 15 meter elements near the center of the arms; then 17 meter

(optional) and finally the 20 meter elements near the tips of the arms. BE SURE that Driven

Element wires are used with Driven Element ARMS, Reflector wires with Reflector ARMS.

The wire ends of all DRIVEN ELEMENTS are terminated at a special DRIVEN ELEMENT

TERMINAL BLOCK as shown In Figure 1. (Separate terminal block for each band) or at the

CUBEX MATCHING TRANSFORMER (optional item).
