Antennas RF Procurement Notes

Verify the specific datasheet version from Amphenol PCTEL or authorized distributors to confirm current manufacturing status and exact mechanical tolerances. Ensure compatibility with existing mounting hardware and vehicle electrical systems before procurement.

Antennas RF Selection Notes

Select this model specifically for transit applications where standard whip antennas exceed height restrictions. Confirm that the 148-160 MHz operational band aligns with local regulatory requirements and fleet communication frequencies.

Antennas RF Part Context

This component belongs to the PCTEL Silhouette series, which specializes in low-silhouette vehicular antennas. These products are engineered for essential transit vehicle installations where maintaining strict overhead clearance limits is critical for safety and operational compliance.

Antennas RF Replacement Considerations

Consult official Amphenol PCTEL documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other low-profile models without verifying electrical and mechanical specifications.
