Your Best AM FM Car Radio Antenna Questions Answered
What Are the BEST AM FM CAR RADIO ANTENNA Types for High Speed Driving?
For high-speed driving, I recommend a durable, low-profile exterior antenna or a highly stable patch antenna. External whips, like the Eightwood 6.8” flexible mast, are designed to withstand wind load without snapping or oscillating wildly. Hidden patch antennas also perform well since they are protected inside the cabin, provided they are securely adhered to the glass and optimized for reception in that location.
How Does Amplification Affect Long-Term Antenna Value?
In my experience, amplification significantly increases long-term value, but only if you actually need it. If you drive in areas with consistently weak signals, an amplified antenna saves you from the frustration of constant static and dropped stations, maximizing your listening pleasure. However, if your signals are already strong, amplification offers diminishing returns and can sometimes introduce noise if the power source is poor.
Is a Hidden Patch Antenna Ever as Good as an External Whip Antenna?
No, fundamentally, a hidden patch antenna cannot achieve the same level of range or gain as a properly mounted external whip, especially a marine-grade or amplified model. The metal structure of the vehicle interferes with reception, and patch antennas often have lower gain figures. Hidden antennas are best for convenience, aesthetics, and basic, close-range reception, not maximum performance.
