2 Antenna's and grounding advise

[hsparks56]

Need advise on the following: Do I need a separate ground wire for 2 antenna's that will be mounted about 15 feet away from each other or can I jump a ground wire to the other and then to my service ground?

You can jump the grounding wire no problem assuming you mean a mast grounding wire and not the coax grounding block(s).
