Towers are usually addressed by the name of the primary municipality served.
Go with Bloomington Tower.

Yeah, I thought so too, but the folks at Willow Run (in Michigan)
didn't care for me calling them "Yipsilanti Tower" a few weeks ago.

Too bad, cuz I really, REALLY enjoyed saying "Yipsilanti" on the
radio...
