I received a NOTAM through AOPA member services about a TFR. I read the NOTAM and understood the TFR would be in effect from XA:30 through XD:15 local time.I understood the TFR extended to a 30 NM radius from the CHS VORTAC. I read that flights at RBW would be affected. I used a NM plotter and sectional to measure the distance from the CHS VORTAC to RBW and found that RBW was just outside the 30 NM radius. Thus; I assumed only flights arriving and departing to the east of RBW and penetrating the 30 NM radius was required to use the ATC services.Previous TFRs at CHS; had not included the RBW airport. I departed RBW approximately XC:35 local to the west. After flying westward for approximately 15 minutes; I turned back toward RBW.With a Garmin GPS and distance measuring from the CHS VORTAC; I carefully flew the pattern at RBW to ensure I did not penetrate the 30 NM radius for the TFR; and I landed back at RBW approximately XD:00. When I arrived at the FBO; I received a call from ATC informing me of a possible violation.It is my belief that I did not violate the airspace and I used due caution to avoid it. If I misunderstood the intent of this TFR; I sincerely apologize. I would never want to create an unsafe condition.I respectfully offer this observation; this TFR was ambiguous in that the airport I used (RBW) was not included in the 30 NM radius; yet the NOTAM stated it would be affected without clarifying how it would be affected. I would offer this suggestion. If an airport is mentioned in the NOTAM; clearly include all the airspace around that airport in the restricted airspace area. Thank you.
GA pilot reported researching a planned TFR and believe was successful in avoiding it; but was advised by ATC of a possible pilot deviation.
