Narrative:

Was on IFR flight plan to lna from apf in VMC. While in contact with palm beach approach destination airport was sighted about 7 mi to my east. While at 1000 ft MSL and while at said distance advised ATC I was canceling IFR which was acknowledged after which I switched to CTAF for lna. Approaching lna I encountered multiple antennae obstacles which were approximately 1600 ft MSL. In order to avoid obstructions I may have climbed above 1200 ft MSL floor of palm beach class C airspace. Having to negotiate and avoid obstacles which penetrate class C shelf creates a hazardous situation when VFR without advisory services from ATC.
