What exactly do you mean?
Co-phased antennas?
Or two different types of antennas?
Maybe i'm just tired, but, it's not sinkin
into to me yet. LOL |

You should have no problem at all, just get the lower 2 meter antenna away from the pole as best you can and set the swr's. |

Yup. Shpouldn't be a problem.
I have the Maco ontop of my tower and a dipole, scanner ant., and a 2 meter ant all on the same tower and it works fine.

Wondering if I can extend my current coax another 100' without affecting the swr. I'm currently at 150' with a 1.1. |

Jtment,
You shouldnt see any change in your swr if the coax is properly prepared.what you may see is a small db loss due to the additional cable and connectors.some of the cheaper so-239 double female connectors have as much as 1/2 db loss at 11 meters and as an example,lmr-400 has .633db loss at 27 mhz with 100 watts.here is a link with a coax loss calculator for the more popular coax cables.
