I know Hy-Gain used to publish a piece on phasing their multi band verticles
such as the Hy-tower but beware.  You need to set phasing for the band you
want the most (say 40) and you will get diminished results on say 80 and 20.
On 15 and 10 you need to model the results.

I any case its as good as a single verticle.

Years ago 1/4 wave was what you used but now they are saying 1/2 wave
(approximately).  The most important part is the coax phasing line not
actual physical distance.

Ask fellows like K4SQR who probably have sold their phasing systems for just
your situation.
