Narrative:

Hovering oge (out of ground effect) covering news event [near cmh] in columbus which is at the 6 mile mark from cmh. I was talking to cmh with assigned squawk and on tower freq. There were six banner tow aircraft over same event. I communicated with them on local traffic advisory frequency as well as their company frequency because they were not talking to cmh. They stated that they would operate at 2000 ft msl and above and I advised that I would operate at 1500 ft msl for separation. They agreed.after operating for approx. 30 min I noticed that one of the aircraft a super cub aircraft towing a banner was getting lower with each orbit. While at a hover at 1500 msl my TCAS alerted that traffic was at 6 o'clock same alt. I did a peddle turn to see the aircraft at my altitude coming directly at me. I took evasive action and called out on advisory frequency that I was at his 12 o'clock same altitude. I had to take evasive action to side step and noted altitude at 1600 msl. His banner was 100 ft below his aircraft. I stated to the pilot that he was at 1600 msl and much lower than the other banners. After that he climbed back to 2000 msl and joined the other banner towers. I completed my operations and departed the area. No further incidents occurred.
