I do not have a DStar repeater but just analog voice and have had a Comet GP-21 up on the top of a 275' tower since june 02. Its been a solid performer for me. I would not recommend a multiband omni as they are usually multi section antennas and that leads to more going wrong with it over time. The base of the tower is at about 100' above sea level. My coverage with the GP-21 is about 25 miles out for the 10watt mobiles over mostly flat terrain. Portables at 1 watt out to about 10 to 15 miles if you pick your spot well.
