Hi Pasquale,

The problem is which manual was the antenna designed FOR?

If you do not know when the antenna was built/sold, then "which
manual" does not make much sense.

As offered, split the difference (choose lengths half way between
different lengths offered) and tune the antenna. The antenna is
probably NOT going to be in tune by simply following dimensions.
Dimensions are simply a starting point. Few antennas are erected in a
tuned condition (they rarely work the first time).

This means you will have to
1. put it together,
2. tune it or build to dimensions (or split dimensions),
3. put it up,
4. measure SWR across frequencies and bands, and
5. take it back down and change dimensions.
Repeat 3/4/5 until all bands measure to satisfaction.

Alternatively, erect the antenna pointing up. This is so you have
access from the ground to make the first tunings. This saves putting
it up and taking it down too much.
