I see it has been 10 months now since they filed the application and it is still pending. How long do these usually take?
Like gimmus said, it looks like an expensive custom antenna for just a gain to the northwest (on paper, at least). It would probably help coverage towards the airport. Right their HD signal starts to come and go for me as I round the hills on the Parkway West near the airport.
They're moving from a Crown Tower in Hazelwood to an American Tower on Mt. Washington. I would assume the Mt. Washington location would have higher rent, being closer to the city center.
I wouldn't be surprised if they get the construction permit and never build it out. Seems to happen a lot in the radio and TV broadcast world. Maybe that's a strategy to block other stations in the next filing window?
Also, does anyone have an idea what a custom FM broadcast antenna like that costs, and what it costs to install?
