Performance and Range Considerations
When choosing a K40 antenna, understanding performance and range is crucial. The K40 antennas are designed with precision, ensuring that users experience minimal static and maximum clarity. The unique capacitor technology incorporated into each antenna allows for consistent Standing Wave Ratio (SWR) across all 40 channels, making them ideal for both casual and serious users.
Installation and Maintenance
Installation Tips
Installing a K40 antenna is straightforward, especially with trunk-mounted options. Ensure that the surface is clean and dry before mounting. For magnetic antennas, choose a flat, metal surface to maximize the magnetic grip.
Maintenance
Regular maintenance can extend the life of your K40 antenna. Inspect the coaxial cable for wear and keep the antenna clean. A simple wipe-down can prevent static and ensure optimal performance, particularly for the magnetic mount.
