Antennas RF Procurement Notes

Verify current lifecycle status as the manufacturer has indicated scheduled obsolescence for this model. Confirm specific datasheet revisions and component supplier changes prior to finalizing procurement plans. Ensure that the N-type female termination aligns with existing system cabling infrastructure. Check for any recent product change notifications affecting internal components or performance specifications before ordering.

Antennas RF Selection Notes

Select this model when a cost-effective omnidirectional solution is required for the 430-440 MHz spectrum. The fiberglass construction offers a balance between durability and weight. Consider the bracket mounting requirement and physical dimensions during mechanical design integration. Verify that the 150 W power rating meets the operational requirements of the connected transmitter equipment.

Antennas RF Part Context

This component belongs to the Phantom series of RF antennas manufactured by TE Connectivity. It is categorized under industrial pressure sensors in some distributor listings due to data classification errors, but it is functionally an RF antenna. The part is distinct from dome-mounted variants like the TRAB4303, utilizing a different mounting style and form factor suitable for base station environments.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The manufacturer has indicated the product is scheduled for obsolescence. Designers should evaluate alternative models within the same frequency range and mounting configuration if long-term supply continuity is required.
