I like how people from Utah chime in here about coverage in California...
But anyway, if you program 155.190 which is Contra Costa SO East Dispatch, it is patched to Pittsburg PD (That is a dispatch contract.) You will have no problems hearing them on that. 460.375 is their main UHF, it should be readable too with outside antenna.
I could hear Antioch VHF from where I used to live in Martinez, which is just north of you, but I used an outside antenna.
