A good general purpose antenna that will cover all the frequencies the SDS-200 will receive is the discone. Discone Antennas | DX Engineering Look at the ones that cover from 25 Mhz to at least 1300 Mhz.
Thanks everyone for your help but I just wanted some input on these new scanners but I went old school and I found a good used Radio Shack Discone put it 3 foot above my roof with 20 foot of rg8 and that's a good start now if I can figure out all the settings I need for p25 phase 2
