The Power of Center-Loading Design
Most budget antennas use Base Loading (coil at the bottom), which traps high current near the base and results in poor radiation. The GRA-CFS20H utilizes an advanced Center Loading structure for a significant performance boost:
50% Higher Efficiency: Both upper and lower sections radiate effectively, offering performance close to a full-size antenna.
Superior SWR Stability: Provides wider bandwidth and remains stable during vehicle movement, regardless of mounting environment.
Stronger Field Strength: Moves the high-current region upward to maximize your signal reach.
