## Discrepancy

DURING APPROACH INTO CVG, THE LOCALIZER INDICATED RED X'S ON PFD 1, 2 & STANDBY.  THE AIRCRAFT RETURNED TO SDF AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE VOR/LOC ANTENNA COUPLER-DIVIDER PER EMB 145 AMM 34-32-12, OPS CHECK GOOD.  MAINTENANCE ALSO REPLACED BOTH VOR ANTENNAS DUE TO EROSION.
