C144-440CS

Antennas RF Overview

The TE Connectivity C144-440CS is a dual-band whip antenna designed for vehicular applications, covering VHF (144–148 MHz) and UHF (440–450 MHz) amateur radio bands. It features a straight whip design with a maximum height of 38.000 inches (965.20 mm). The antenna provides 2 dB gain on the VHF band and 5 dB gain on the UHF band, maintaining a VSWR of 1.5. It utilizes an NMO base mount interface for secure installation.

Antennas RF Feature Summary

• Dual-band operation supporting both VHF and UHF amateur radio frequencies
• Straight whip construction with integrated spring mechanism
• Omnidirectional radiation pattern suitable for mobile communications

Antennas RF Applications

• Vehicular amateur radio installations
• Mobile communication systems requiring dual-band coverage
• External mounting on vehicles using NMO base stations

Antennas RF Procurement Notes

Verify that the required NMO base mount is ordered separately, as it is not included with the antenna unit. Confirm compatibility with existing vehicle mounting hardware to ensure proper mechanical fit. Check lead times as the item is often supplied on order rather than from immediate stock. Ensure the specific CS suffix variant matches the desired spring configuration in the final assembly.

Antennas RF Selection Notes

Select this model when dual-band performance across 144–148 MHz and 440–450 MHz is required for mobile use. Consider the 38-inch height for clearance constraints during installation. Choose this part over single-band alternatives if simultaneous VHF and UHF operation is necessary without additional antennas. Verify that the NMO mounting style aligns with the intended vehicle roof or trunk setup.

Antennas RF Part Context

This component belongs to the C144/440 series of dual-band antennas manufactured by TE Connectivity. It is specifically engineered for amateur radio enthusiasts requiring reliable mobile communication capabilities. The product line focuses on robust construction for vehicular environments, offering standardized mounting interfaces like NMO bases for widespread compatibility across different vehicle types.

Antennas RF Replacement Considerations

Direct substitutes within the same family include the C144/440C variant, which shares similar dual-band specifications but may differ in physical construction details such as the presence of a spring element. Users should verify mechanical dimensions and mounting requirements before swapping between these closely related models to ensure seamless integration.
