Thanks for the info.
The reason I asked is because I was wondering if that would give the 1480 / Kentwood allocation a little more freedom with regard to signal propagation to the south.
Seems to me a diplexing at the WOOD 1300 site may be feasible. Probably won't ever happen, though.
The big boys (IHM, Cumulus, Townsquare, etc.) are very cantankerous about sharing towers and lease costs and conditions. Yes, I think a diplex would work at the WOOD site, but at that distance, and the slight azimuth compromise (3 degrees), has often required surprisingly drastic reductions. When they did the Proof of Performance, they found the radials were only 2 mS/m as opposed to 8 mS/m, which shows for all of Kent county on the M-3 Map. This showed up online when WCCW 1310 applied for 50 kW Daytime and they extended the WOOD POP radials.
If there were some mutual benefit that could be realized, like adding a fifth dogleg tower like the fourth dogleg tower did at WJMK 1250, which allowed 5 kW Day and 1.1 kW Night, that might do it. Hopefully, WOOD could also to figure out how improve their pattern somewhat, especially to the West. 1480 has a much higher NIF compared to WOOD. Think of the dogleg as rotating the pattern and nulls slightly, and allowing null filling on one side. They would still be better off for WMAX...WGVU 1480 at WJRW 1340 or nearby for the Day site. Did they ever clean up the toxic mess there?
WMVP 1000 changed their Night pattern (and Day slightly) with a new dogleg array to do just that, according to the late great Glen Clark. I wonder what happened to his multinode computer. That could come in handy in designing diplexes optimally. I think Ron Rackley might have, but he sadly passed away nearly contemporaneously.
