> My two high stack switch design is simple using only RG-83 (35 ohm coaxial
> cable) to match 2 parallel 50 ohm loads and another 1/4 wavelength of RG213
> is used when feeding the single Yagi's so that the line length to the
> amplifier is not changed regardless of antenna selection. This keeps the
> VSWR at the same point which keeps the amplifier happy regardless of antenna
> combination.
>
> I also have a design that incorporates a both-out-of-phase (BOP) selection.
> This creates a high angle lobe. We use this feature on 40 and 20 meters.
>
> I use these designs for all of my 2,3 and 4 high stacked Yagi arrays.
>
> The secret to good Yagi monoband stacking is using exact ODD quarter
> wavelength feedlines (current forcing) to feed the individual Yagis.

> I would be happy to scan my two high design and email it to you if you like.
