Antennas RF Procurement Notes

Verify the specific ordering suffix to ensure compatibility with the intended mounting interface and connector type. Confirm that the required frequency band aligns strictly with the 450-470MHz specification. Check for any recent Product Change Notifications (PCN) that may affect physical dimensions or material composition. Ensure the application environment does not exceed the 150W maximum power rating. Consult the official Phantom Elite datasheet for detailed mechanical drawings and environmental ratings prior to final procurement.

Antennas RF Selection Notes

Select this model when high-performance diversity reception is required in the UHF band. The NMO base mount is standard for many vehicle platforms; verify roof compatibility before purchase. Consider the Phantom Elite series advantages over standard whips if signal reliability is critical. Compare physical dimensions against available mounting space, noting the 3.400-inch height. Evaluate the 3dBi gain against system link budget requirements.
