INTRODUCTION
Some UltraBeam models work in 30 and 40 meters with folded elements, this allows you to work
30 and 40 meters with full-size elements in the same size 6-20 models.
This technique is applied on 2 and 3 element Yagi models.
On these two models curves are applied to the ends of the elements, joined together by
fiber glass tubes, this creates a corridor in which the copper tape can scroll to reach the required
length to resonate up to 40 meters.
Figures 1 and 2 show in red the path and the shape of a "C" that the folded dipole assumes when
operating on 40 meters.
NOTE: This manual only refers to the installation of the curves, side elements
and other specific parts of the models who work in 30 and 40 with folded elements.
For all other antenna assembly instructions refer to the manual "Standard"
