[TowerTalk] phasing verticals

[w5jmw at towerfarm.net]

Hello all,I have a phasing box.It is desigened for the coax to attach to 
the back.Ant1 Ant2...It has different loading inductance between 80 and 
160.Also the ability to change the distance of the phasing.1/4 spacing 
1/2 wave etc.....My question...what lengths or multiples should be used? 
or does it matter with this.It has 2 swr indicators.one for ant1 and 
ant2...If the length doesn't I would think they must be equel lengths? 
comments?
