C144-440C

Antennas RF Overview

The TE Connectivity C144-440C is a dual-band whip antenna designed for amateur radio applications, covering VHF (144–148 MHz) and UHF (440–450 MHz) bands. It features a straight mechanical style with an NMO base mount interface. The antenna provides a gain of 2 dB on the VHF band and 5 dB on the UHF band. It supports a maximum power handling of 200 watts and maintains a voltage standing wave ratio (VSWR) of 1.5. The physical height is 38 inches (965.20 mm).

Antennas RF Feature Summary

• Dual-band operation supporting both VHF and UHF amateur radio frequencies.
• Straight whip design with NMO base mounting interface.
• Optimized gain performance with 2 dB on VHF and 5 dB on UHF bands.

Antennas RF Applications

• Amateur ham radio communications.
• Dual-band mobile radio installations.
• Separate VHF and UHF radio setups using a single antenna structure.

Antennas RF Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting styles. Confirm that the NMO base mount is ordered separately if not included in the specific package configuration. Check RoHS compliance status and lead times directly with authorized distributors or TE Connectivity official channels prior to procurement.

Antennas RF Selection Notes

Select this model for fixed-mount vehicle or station applications requiring simultaneous VHF and UHF coverage. Ensure the installation site accommodates the 38-inch height. Verify that the connected radio equipment supports the specified frequency ranges and power levels within the antenna's operational parameters.

Antennas RF Part Context

This component belongs to the Laird TE Connectivity dual-band antenna series. It is part of the C144/440 family, specifically engineered for high-performance amateur radio use. The product is currently active and manufactured by TE Connectivity under the Laird Connectivity division.

Antennas RF Replacement Considerations

The C144/440CS is a related variant featuring a spring-loaded element instead of a straight whip. Verify mechanical fitment and electrical characteristics when considering substitutes from the same product family.
