Upgrading to a better antenna is often the most effective way to improve radio reception. Consider these options:

* **External Antenna:** An external antenna, mounted outside your home, will provide the best possible reception. Choose an antenna that is specifically designed for the frequency range you want to receive (AM, FM, or both).
* **Amplified Antenna:** An amplified antenna includes a built-in amplifier that boosts the signal strength. This can be helpful in areas with weak signals.
* **Directional Antenna:** A directional antenna is designed to receive signals from a specific direction. This can be useful for focusing on a particular station and reducing interference from other sources.

**Choosing the Right External Antenna:**

* **FM Antennas:** For FM radio, a simple dipole antenna or a multi-element Yagi-Uda antenna can significantly improve reception. A Yagi-Uda antenna is directional and offers greater gain.
* **AM Antennas:** For AM radio, a loop antenna or a long wire antenna can be effective. A loop antenna is less susceptible to interference, while a long wire antenna can capture signals from greater distances.
* **Outdoor Installation:** Mount the external antenna as high as possible and away from any obstructions. Use proper grounding techniques to protect the antenna and your radio from lightning strikes. Follow the manufacturer’s instructions for installation and grounding.
