- Page 2 Introduction Some UltraBeam models work in 30 and 40 meters band with folded elements, this allows you to work on 30 and 40 meters with full-size elements in the same mechanical dimensions of UltraBeam 6-20 models. This technique has been applied on 2 and 3 element Yagi models. In order to achieve that two curve models are applied to the ends of the elements, joined together by glass fiber tubes, this creates a corridor in which the copper tape can scroll to reach the required length for resonating up to 40 meters.
- Page 3 PVC GUIDE TUBES DRIVER 30-40 All UltraBeam models working in 30 and 40 meters with folded elements include the installation of internal guide pvc tubes to the left and right elements attached to the motor unit. MOTOR telescopic element The guide tube of folded elements is essential to allow the tape to slide within the curve and the side elements without bending.
- Page 4 INSTALLATION OF ELEMENTS ON MOTOR UNIT Before inserting the elements in the motor unit it is necessary to fix the PVC guide tube. During this operation it is necessary that the element remains aligned to the engine, if your set-up assembly does not allow this, the help of a second person is absolutely needed to support the element during the insertion of the guide tube.

- Page 6 2 ELEMENTS YAGI 6-40 To apply the thermo shrinking a heat gun is needed (1500-2000W) The heating time varies depending on the outside temperature, and in any case the correct temperature is reached when the inner glue comes out, creating a ring all around the edges. Insert the side tube and the ends of the elements in the curves up to the maximum insertion (fig, 1).
- Page 7 Combine the 1400 mm pipes placing the 10 cm small tubes exactly at half junction (fig.4-5). Slide the sleeves on joints and heat up to the correct temperature (Figure 6) Drill a small 2-3 mm hole on the same axis in the center in both junctions (fig.7) NOTE: It’s important to check that the holes are facing down before heating conduits that hold whole side element to the curves Fig.4...

With regard to the assembly instructions of the curves and side elements, they are absolutely identical to those of UB50 described in this manual.
