John, You will get as many positive answers as you will negative. That said, the proper way would be 2 antennas and 2 runs of coax. If you already have the dual band antenna and want to go that route there are several things to watch out for. What is the power rating of your antenna? If you have 2 repeaters putting out 100 watts into an antenna rated at 100 watts, you will damage the antenna. At the ground end, you will need a diplexer to split the single run of coax into one for each repeater. The diplexer will have the same power restrictions as the antenna. Without keeping these two restrictions in mind, you may spend more $$ the second time around.
