🧭 Broadcast Tower Compass — Which Way to Point Your Antenna

Each dot is a local TV tower relative to your center point (● Green = Strong, ● Blue = Moderate, ● Amber = Weak).

Primary Aim Direction: WSW (241°)

Place your indoor antenna near a window or exterior wall facing WSW (241°), or aim your attic/rooftop antenna toward that compass bearing for the strongest signal lock.
