Hi:
There is a large amount of interaction between the dipoles as they are
tightly coupled to each other.
The shorter or higher frequency are affected more by changes to the lower
frequency i.e. longer dipoles than the lower frequency dipoles are by
changes to the higher frequency or shorter dipoles.
So to keep hair pulling to a minimum start with the lowest frequency dipole,
tune that for the lowest SWR or for resonance and then do the next lower
one. If you do it in any other order you will spend your life going back and
forth retuning dipoles until you give up and buy a G5RV kit and join the
dark side.

Building something a bit like this :

He suggests setting up one wire at a time starting with the longest, is

the easy way ?

I would think adding all wires, a bit too long , and then starting the
adjustment with the shortest would be better ?
All the other wires overlap the shortest 100%, so I would imagine later
trimming of longer wires i parallell would not affect the short wire
much.

You are placing far too much importance on your objective of having
each dipole resonant. It matters oh so very little from any point of
view.


What would the purpose of building a multidipole be if not to get a
resonance on each band ?

My goal is to run psk31 on several bands without a tuner.
