G420BN

Antennas RF Overview

The TE Connectivity G420BN is a passive whip antenna designed for UHF communication applications. It operates within the 420 MHz to 450 MHz frequency range, centered at 435 MHz. The component features a BNC male connector for termination and mounting. It provides a gain of 2.5 dBi with a VSWR of 1.5:1. The antenna has a 50 Ohm impedance and a power rating of 50 W. It measures 10 inches in length and functions between -40°C and +85°C.

Antennas RF Feature Summary

• Base-loaded 1/2 wave flexible cable design
• PVC coated construction for durability
• BNC male connector mount style

Antennas RF Applications

• UHF communication systems
• Two-way radio installations
• ISM band operations

Antennas RF Procurement Notes

Verify the specific datasheet version before procurement, as specifications may vary by revision. Confirm that the BNC male connector matches the receiving equipment interface requirements. Ensure the 50 Ohm impedance aligns with the system transmission line characteristics. Check environmental ratings against operational temperature extremes. Validate compliance with local regulatory standards for the intended frequency band usage.

Antennas RF Selection Notes

Select this model when a base-loaded whip antenna is required for UHF frequencies between 420 MHz and 450 MHz. The 2.5 dBi gain offers improved performance over standard quarter-wave antennas. The 50 W power rating supports moderate transmission power levels. Consider the 10-inch length for space constraints in installation environments. The PVC coating provides protection against environmental factors during outdoor use.

Antennas RF Part Context

The G420BN belongs to the Tuf Duck series of antennas from TE Connectivity. These are passive, base-loaded whip antennas designed for robust UHF communication. The series typically includes variants for different frequency bands, such as the G400TN for 400-420 MHz. This specific part number addresses the higher end of the UHF spectrum.

Antennas RF Replacement Considerations

The G400TN is a similar base-loaded whip antenna from the same manufacturer but operates in the 400-420 MHz range. Verify frequency compatibility before substitution, as the G420BN covers 420-450 MHz. Both parts share the BNC male connector and whip form factor. Ensure the replacement meets the specific frequency requirements of the application.
