They're already on the Parma stick. What you hear is what you get.
The application to move to Parma (the WBNX-TV/WMJI site) shows an antenna pattern with 10 dB of suppression across an 80 degree arc centered northwest; in other words, power in that direction is not supposed to exceed 25 watts. This reduction was deemed necessary to keep the interference contour from crossing the Canadian border.
How does it actually cover in that direction? Also, I wonder how it was possible to modify the specified ERI FM-100 (normally, a 'non-directional' antenna bay) to comply with that unusual envelope, which also pulls down to 40 watts towards the east and southeast. At least it would be interesting to see what side of the tower it's mounted on, and how the parasites (if any) were configured. Perhaps it doesn't actually make the full 250 watts in any direction.
If anyone in the area is inclined to drive over and take a look, note that the CP application specified an antenna height of 780 ft (238 m) above ground, which would put it about 260 ft above the WMJI aux.
