A commercial fixed wing flight crew received an egpws terrain and a low altitude alert warning from mgw tower while descending to cross uddov intersection at 2;800 MSL on the VOR-a approach. Reporter believes the crossing altitude is in conflict with a charted 2;409 MSL obstruction (a tower) along the course from mgw VOR to uddov.

Narrative:
We were flying the VOR-a to mgw for landing on runway 36. Visual with the airport was observed at 1.0 DME from mgw VOR and 2;900 MSL. At mgw 337 degrees/1.0 DME and 2;800 MSL; egpws (obstacle; pull up) warning annunciated in cockpit with a subsequent low altitude alert warning from mgw tower. There is a radio tower at 2;425 [2;409] MSL along the final approach course and it was in sight. A turn correction to the right was performed to avoid the tower. Visual with the ground was maintained from 3;000 MSL and below. VOR-a approach altitudes and final approach course were followed. No further warnings were annunciated or observed and the aircraft landed safely on runway 36.I suggest the company and/or FAA review[s] the published altitudes for this particular approach and the approach itself. There is only slightly less than a 300 ft clearance between the tower/obstacle along the final approach course and the published step down altitude (2;720 ft) (for which 2;800 ft must be entered into the altitude pre-selector). Previous GPWS warnings have occurred on this approach. Also; this is the only approach that is available for a non-circling landing on runway 36 for aircraft not equipped with GPS or RNAV.
