SMA PLT IN PROX OF OBSTRUCTION TWR IN DEP PROC.

Narrative

I TOOK OFF FROM RWY 9L WITH A CLRNC FROM THE TWR TO MAKE A SE DEP. I KNEW I WOULD BE FLYING TOWARDS AN ANTENNA FARM (WHICH HAS ABOUT A DOZEN TALL RADIO AND TELEVISION ANTENNAS; THE TALLEST OF WHICH REACHES 1049 FT MSL (1044 FT AGL). BEING AWARE OF THIS ANTENNA FARM IS A NORMAL CONCERN FOR PLTS BASED AT NORTH PERRY ARPT. BECAUSE THESE ANTENNAS ARE SO CLOSE TO THE ARPT; THEY ARE ALWAYS ENCOUNTERED AS AN OBSTACLE DURING SE DEPS. DURING MY CLBOUT; I HEADED BTWN 2 ANTENNAS THAT WERE 997 FT MSL (985 FT AGL) AND 743 FT MSL (733 FT AGL); PLANNING TO BE ABOVE 1000 FT MSL WHEN I REACHED THESE ANTENNAS. DURING THE CLB; THE ANTENNAS WERE OUT OF SIGHT DUE TO THE PLANE'S CLB ANGLE; SO I OCCASIONALLY LOWERED THE NOSE OF THE PLANE TO VISUALLY CHK THE LOCATIONS OF THE 2 ANTENNAS. WHEN I REACHED 1100 FT; I LEVELED OFF AND NOTICED THAT I WAS PASSING THE 997 FT ANTENNA ABOUT 100 FT ABOVE IT AND ABOUT 300 FT HORIZ OF IT. I KNEW THAT THIS WAS TOO CLOSE FOR COMFORT. I SHOULD HAVE MADE 1 MORE VISUAL CHK AND ALTERED COURSE SLIGHTLY TO FLY MORE IN BTWN THE 2 ANTENNAS. I CONTINUED MY FLT AND SOON OVERFLEW THE INTRACOASTAL WATERWAY. I TURNED S; FOLLOWING THE CANAL SYS WHILE DSNDING DOWN TO 800 FT. I DSNDED BECAUSE I WAS PLANNING TO FLY UNDER THE 1000 FT FLOOR OF THE MIAMI CLASS B AIRSPACE (FORMERLY MIAMI TCA); WHICH BORDERED BISCAYNE BAY; THE AREA I WAS HDG FOR. WHEN I GOT TO 800 FT; I GOT A CALL FROM THE CTLR IN NORTH PERRY TWR. HE ASKED ME TO IDENT. I DID; THEN HE ASKED FOR MY FINAL DEST. I TOLD HIM I WAS GOING TO OVERFLY BISCAYNE BAY; THEN HEAD BACK TO NORTH PERRY ARPT. AT THIS POINT; I FIGURED THAT EITHER SOMEONE RPTED MY CLOSENESS TO THE ANTENNA OR MY DSCNT TO 800 FT OVER THE INTRACOASTAL WATERWAY. I WAS EXPECTING TO GET A CALL FROM THE CTLR WHEN I GOT BACK TO THE ARPT; BUT I DIDN'T. I LEARNED FROM MY ERRORS AND DECIDED TO FILE A NASA ARC 277 FORM SO THAT OTHER PLTS CAN LEARN AS WELL.
