Ion Bernstein wave (IBW) antennas are known to have substantial localized effects on the plasma edge. To allow better understanding and measurement of these effects, the TFTR edge reflectometer has been relocated to the new IBW antenna. This move was facilitated by the incorporation of a diagnostic access tube in the IBW antenna identical to the original diagnostic tube in the fast-wave (FW) antenna. This allowed the reflectometer launcher to simply be moved from the old FW antenna to the new IBW antenna. Edge density profile modification during IBW experiments has been observed. Results from IBW experiments are presented and contrasted to the edge density modifications previously observed during FW heating experiments. {copyright} {ital 1997 American Institute of Physics.}
