While some agencies bought and deployed the same radio model across the board, others opted to buy multiple radio models and multiple antenna types. PennDOT was one that went variable. Some agencies are all Kenwood, some are all Motorola. PennDOT seems to have bought at least one of everything and has opted deploy equipment based on what will work best in a given district. I can tell you the trucks local to me all sport the Motorola multi band antenna, but PennDOT definitely has other antenna models in service.
