I just picked up a used Apelco (see topic) and need an antenna. Apelco has 86'd this unit from service. Will the newer antennae work? I also need data cables, if anyone has a set, or could post a photo of the ends of the cables (male) I'd be appreciative. There is a chart chip in the unit, marked 12220. I can't find a chart that corresponds with that number. Anyone? Larry Wilson Richmond,Va.
