• Outdoor UHF communication systems
• Fixed wireless access points

Antennas RF Procurement Notes

Verify the specific frequency band requirement against the datasheet, as some sources cite 450-460 MHz while others mention dual-band capabilities up to 941 MHz. Confirm the connector type and mounting hardware compatibility with existing infrastructure before ordering. Ensure environmental ratings meet site-specific exposure conditions.

Antennas RF Selection Notes

Select this model for applications requiring robust outdoor performance at 450-460 MHz. Consider the 44-inch length for clearance requirements. Evaluate the 5.15 dBi gain against site propagation needs. Verify power handling limits relative to transmitter output specifications.

Antennas RF Part Context

Part of the TE Connectivity Phantom Elite or FG series lineup, focusing on reliable RF transmission. Designed as a replacement or upgrade for legacy base station antennas requiring higher durability and specific UHF frequency coverage.

Antennas RF Replacement Considerations

Check for direct substitutes like ETRAB4503 or TRAB4503 if NMO base mounting is required instead of bracket mount. Verify frequency overlap and gain differences when comparing with other TE Connectivity whip antennas.
