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.
