A little more context: it was the cross-service translator for KATZ(AM). The tower is shown as owned by the Communications Fund, which was the name of one of Richard J. Miller's corporate entities. Miller, long since passed, once owned KADI(FM, 96.3) and KXLW/KADI/KKOJ (AM, 1320).
Edit: I was hoping this might have been the old KADI tower, but it turns out that tower was nearby, but on the other side of Manchester Road, but still in Brentwood.
