Poledo: you refer in your first post to the "old 1360" towers. The original 1360 two tower site, built in 1960 near the mouth of the tunnel, is gone ... Austal's expansion wiped that out. WMOB 1360 now uses what used to be the 1410 site that goes back to well before 1960... it was WODX, then WALA, then WUNI, then WMML, then WLVV, and now WNGL from a different, inland site.
WMOB was fortunate that WNGL let go of the site; otherwise, they would have been up the creek. Apparently they were able to make their DA requirements fit the tower positioning. They were also fortunate that 1360 Monroeville went silent, as 1360 Mobile had a deep DA-D null for that reason. They probably also protected 1370 Pensacola to a slight degree.
I see in radio-locator that WMOB now has 9 kw day instead of the original 5; that is probably thanks to the demise of Monroeville.
You may notice also that there is a monstrous celltower very close to the AM's site; I have wondered whether it distorts the AM's pattern.
How old is the 1410 site? It is Mobile's oldest station. I have a 1930 log which contains a display ad for "WODX, on Mobile Bay" so it may go back that far. Those towers, in any case, are o-l-d. They've been out in the salt air for a long time and have been thru many hurricanes. A fresh coat of paint is cosmetic, but I wonder what the steel is like under the paint.
