Antennas RF Procurement Notes

Verify the specific frequency band requirement against the model variant, as Amphenol PCTEL offers similar antennas for different ranges such as 210-230 MHz. Confirm the mounting type matches the installation surface. Check for any specific connector requirements if an adapter is needed. Ensure the power rating aligns with the transmitter output.

Antennas RF Selection Notes

Select this model for applications requiring a 3 dB gain in the 138-174 MHz band. Consider the magnetic mount for non-permanent installation on metal surfaces. Evaluate the 150 Watt power limit against peak transmission levels. Compare with other collinear designs if higher gain or different frequency coverage is required.
