3. Setup and Installation
Follow these steps to properly install your Ancable FM Antenna:
- Identify the FM Antenna Input: Locate the FM antenna input jack on the back of your stereo receiver. This is typically labeled as "FM 75 Ohm UNBAL," "FM ANT," or similar. It will be a female F-type coaxial connector.
- Connect the Antenna: Gently push the F-type male connector of the Ancable antenna into the corresponding female F-type jack on your receiver. Ensure the connection is firm and secure.
- Position the Antenna for Best Reception: For optimal FM signal reception, stretch the wire antenna as far as possible away from the receiver and other electronic devices. Experiment with different orientations and locations within your room. Placing the antenna near a window or along a wall often yields better results.
