Antennas RF Procurement Notes

Verify the specific connector type and cable assembly requirements against system specifications before ordering. Confirm that the operating environment temperature falls within the -40°C to +85°C range. Ensure the installation location accommodates the physical dimensions of the 100-inch whip. Cross-reference the 50-Ohm impedance with existing RF infrastructure components to maintain signal integrity.

Antennas RF Selection Notes

Select this model when a high-gain omnidirectional solution is required for mobile applications in the 896–940 MHz band. Consider the mechanical constraints of the 100-inch whip length during vehicle design. Evaluate the need for the chrome finish for corrosion resistance in harsh environments. Compare against other series if different mounting styles or lower profiles are necessary.
