PA-28 pilot reported a near midair collision over the miami beach shoreline with a helicopter flying...

Narrative:

While operating VFR flight under the miami class B over the miami beach shoreline; [helicopter] flew opposite direction with less than 100 feet vertical/horizontal separation of the reporting aircraft; a piper warrior. At the time of the near miss; both aircraft were making position reports on the 123.05 reporting frequency. Reporting pilot was flying northbound; conflict aircraft was flying southbound. In the same area there was an aircraft towing a banner; which both aircraft were trying to avoid; and probably became a mutual distraction. Reporting aircraft is equipped with traffic information services (tis); conflict traffic was not being depicted; and no traffic alert was issued by tis. Radio position reports may have been interrupted in error by having two helicopter pilots reporting in the area under the call sign '[helicopter].' traffic was not in sight given that the helicopter was slightly lower and obstructed by the cowling. Situation could be avoided by establishing recommended corridors when flying under the miami class B; by pilots providing more frequent position announcements; and by reporting pilot continuous visual scan instead of being briefly fixated on banner towing aircraft.
