The models UB20 and UB40 differ from UB50 MX for the size of the elements and boom and why
they work in a configuration 2 elements moxon on the lower frequency.
With regard to the assembly instructions of the curves and side elements, they are absolutely
identical to those of UB50 described in this manual.
On these two models the PVC guide tubes will be installed on both the external antenna
elements.
The figures show the copper tape path that allows the two antennas to act as a 2 elements
