You should check with your local hams to see what band the primary Skywarn or ARES repeater is on.
Here in my county, it is on 440 band (UHF). I know of 6 counties throughout Illinois where most nets are on 440, and very little activity is on 2 meters.
So I would Highly, highly recommend the FT7800 dual-band mobile. That will let you interface with 90% of ham repeaters around the country.
But with the 440 band, gain is your friend, so a 1/4 dual band antenna, may not be the best choice, unless you just cant have a larger antenna.
For radio, antenna, and antenna mount, you are looking at a little less than $300 for brand new.
Good luck.
