Hi All, Here it is, the Cubex Cubical Quad 6 elements has arrived in two boxes and we are ready to assemble it, we think it will take us one to two days to put it up on top of the tower. Check the boxes contentTwo boxes has arrived at home, the longest one contains the boom in 3 parts and the 12 spreader arms (fiber glass) that will be assembled onto the boom. This spreader arms are themselves made of 5 parts and we will have to assemble them using screws. The second box contains all the screws and parts that helps tighten the different elements together. All parts are colour marked when necessary what will ease the assembly task. Installing the rotatorThe rotator that will be used is a Yaesu G1000C, this one has been bought on Ebay but seems as new. We checked it before installation and it works perfectly. The rotator will be screwed in the tower cage, and the tube of 1 centimeter thick that will support the Quad will be tightened in the rotator jaws. 
Mounting the boom on the towerWe encountered a problem when trying to attach the boom on the arrow tube, the tube is 60 millimeter of diameter but the fixations that where shipped with the Quad are 50 millimeter, so we had to make new holes on the plate that ensures the fixation of the boom onto the arrow tube. Attaching the spreader arms onto the boomWe will first attach the 6 spreader arms which are on the same horizontal plane onto the boom, it will be much easier for us because the boom is still up the ground at 2.5 meter. During all this process the boom had to be rotated and if we had attached the spreader arms on the horizontal plane and vertical plane at the same time, we certainly encountered problems rotating the boom. So for each spreader arm we take the center part with its next two elements already screwed on it and we swip all this part into the appropriate boom hole. As you can see on the following picture the boom is marked with colours and you can find the same colours on each corresponding spreader arm. The red arrow shows you a small metallic part that emerges from each center spreader arm, nothing is mentioned about it on the Cubex documentation that helped us assembling the Quad, but we really had problems with it. In fact as it emerges so much from the spreader arm, we were enable to swip the spreader arm center part into the boom, so we had to filed the boom hole on each side to allow the spreader arm to swip naturally into the boom. Then we had to screw the center part onto the boom as shown below 
Here is the result after a few spreader arms have been installed 
Need a 6 elements Yagi ? Form the crosses All spreader arms are assembled, it looks like a Quad no ? 
We do not encountered any real difficulties during this first assembly task, mainly due to the fact that all parts are marked with colours when necessary and holes are already drilled, thanks to Cubex. The next part of this article will show you the installation of the copper wires onto the spreader arms and the Quad raised on top of the tower.
