Assembling the Cubex Cubical Quad 6L Episode II Print

Hi Guys,

We are back for the second part of this article that will show you the end of the Cubical Quad 6 elements assembling.

We ended the previous article with all the Quad spreader arms attached on the boom, we now have to attach the copper wires onto the spreader arms and tighten all the parts together.

Attaching the copper wire on the Driven Element

We strictly followed the Cubex documentation and began to attach the first copper wire on the Driven Element, holes were already drilled at the spreader arms extremities (the black parts) and we just had to insert the wires into them, the loop formed by the wire will be attached to the Terminator Block (the small white square depicted on the picture below) only when all the arms will be fitted with their wires (shown here already attached because the insert picture has been taken at the end of the process).

Driven Element 


Don't forget to shake the spreader arms before tightening/soldering

In a way to ensure that the copper wires get the right tension it is not sufficient to apply the tension manually on the two extremities of the copper wire and then solder.

Don't forget that BEFORE tightening and soldering the wire coupler and the copper wire, you MUST operate a relatively strong shake with your hand on the spreader arms, the copper wire will find its right place on the spreader arms and loose some of his tension, you will then have to re-tension a little bit the wire. 

Only after this can you tighten the wire coupler and then solder it with the copper wire. 

Have a look at the Video available in the Video section.

Attaching the copper wires on the Directors and the Reflector

The following picture shows one of the 5 wires that had to be attached to the Directors and the Reflector, the task is relatively easy but two persons are necessary because you have to apply the right tension on the wire and at the same time tighten the wire coupler (the small metal part shown on the picture), which blocks the loop.



Soldering the coupler and the copper wires

When the wires have been tightened with the coupler, we had to solder them.

We also soldered the wires on the terminator block of the Driven Element

At the end of the process all the copper wires have been attached and soldered, here is the final result


Raising the Quad

It took us 8 hours to complete all the tasks described in Episode I and II (two persons), at the end of the process we had to raise the Quad because a rainy storm was coming. Here is the Quad on top of the tower, the Quad is swinging due to a light wind coming with the storm.

A hard work and a great day for the two Brothers in hams !
