Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required mounting hardware and connector types. Confirm that the NMO base specification aligns with existing vehicle roof preparations. Request updated datasheets from authorized TE Connectivity distributors to validate current production status and any recent design modifications prior to final procurement decisions.

Antennas RF Selection Notes

Select this component when a fixed-gain VHF solution is required for mobile installations. Ensure the operating environment does not exceed the 100W power rating. Verify that the physical dimensions fit within the available space constraints on the target platform. Consider environmental sealing requirements if the installation location is exposed to harsh weather conditions beyond standard automotive standards.

Antennas RF Part Context

This model belongs to TE Connectivity's vehicle antenna portfolio, specifically targeting VHF frequencies. It complements other mobile antennas by offering a standardized NMO mounting footprint. The product line focuses on reliable signal transmission for professional mobile radio users requiring consistent coverage in the 2-meter band range.

Antennas RF Replacement Considerations

Direct substitutes must match the 144-174MHz frequency range, NMO base type, and similar gain characteristics. Verify mechanical height constraints before swapping models. Cross-reference with TE Connectivity's official replacement matrix for legacy part numbers to ensure functional equivalence without redesigning the mounting infrastructure.
