Re: phasing two arrows



If you're talking about the dual band antennas, you can't stack them for
both bands. The spacing will only be correct for one of the two bands.

If you do stack two single band yagis, you have to decide on what
polarization you want. You can get linear vertical, linear horizontal, or
circular. The circular will require a delay line to one of the two antennas.

The dual band arrow antennas are not suitable for stacking because of my
initial comments above. I wouldn't bother, it can't possibly work right on
one of the two bands.
