Antennas RF Procurement Notes

Verify the specific manufacturer designation when sourcing, as Tallysman products are part of the Calian portfolio. Confirm that the required configuration matches the standard 50 cm RG174 cable length and SMA female bulkhead jack interface. Ensure compatibility with existing mounting surfaces for magnetic or screw installation methods prior to purchase.

Antennas RF Selection Notes

Select this model for applications requiring simultaneous GNSS and Iridium signal reception in a compact form factor. The active design provides necessary amplification for weak satellite signals. Consider the magnetic and screw mounting options for flexible integration onto various vehicle or equipment surfaces without complex structural modifications.

Antennas RF Part Context

This component belongs to the TW2643A series of single-band GNSS antennas. It represents a specialized solution combining standard satellite navigation tracking with low-earth orbit communication reception capabilities. The product line emphasizes durability and precision for mission-critical environments where reliable positioning and data link connectivity are essential.

Antennas RF Replacement Considerations

Cross-reference with other models in the TW2643A family if different cable lengths or connector types are required. Verify that substitute parts maintain the same SMA female interface and support the identical 1.559–1.6265 GHz frequency range to ensure system compatibility.
