Antennas RF Procurement Notes

Verify part number accuracy against official TE Connectivity documentation before procurement. Confirm that the NMO base configuration matches the installation requirements. Check current product status as components may be subject to discontinuation notices. Ensure environmental compliance data aligns with project specifications. Cross-reference datasheet revisions to confirm electrical parameters remain unchanged.

Antennas RF Selection Notes

Select this model when a 159MHz UHF whip antenna is required for vehicle mounting. The NMO base ensures compatibility with standard vehicular roof mounts. Consider the 35.5-inch height for clearance constraints. Verify power ratings against transmitter output levels. Ensure the operating frequency range covers the intended application bandwidth without interference.

Antennas RF Part Context

This component belongs to TE Connectivity's Mobile Load Coil Antenna series. The CW1440 shares design characteristics with other models in the CW family, such as the CW4405C, which also utilizes an NMO base and similar whip architecture. These antennas are engineered for robust performance in harsh vehicular environments.
