CWB4405CS RF Antenna 455MHz Whip Straight NMO Base Mount

Part Overview

The CWB4405CS is a 455MHz whip antenna with straight configuration and NMO base mount termination, designed for UHF band applications within the 440MHz to 470MHz frequency range. This component delivers 5dB gain with a maximum power handling capacity of 200W and VSWR of 2.

The CWB4405CS carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and new production requirements where this antenna specification remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWB4405CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency (Center/Band): 455MHz
• Frequency Range: 440MHz – 470MHz
• Antenna Type: Whip, Straight
• Termination: NMO
• Mounting Type: Base Mount
• Gain: 5dB
• VSWR: 2
• Power – Max: 200W
• Height (Max): 35.500" (901.70mm)

The substitute part CW4405CS meets all mandatory electrical and mechanical parameters. The primary distinction is product status: CWB4405CS is Obsolete, while CW4405CS is Active. Both parts are manufactured by TE Connectivity Laird and share identical RF performance characteristics and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

CW4405CS is the direct substitute for CWB4405CS based on the following factors:

1. Electrical Equivalence: All RF parameters are identical, including frequency band (455MHz center, 440–470MHz range), gain (5dB), VSWR (2), and power handling (200W).

2. Mechanical Compatibility: Physical dimensions, termination type (NMO), mounting configuration (Base Mount), and antenna form factor (Whip, Straight) are identical.

3. Product Status: CW4405CS carries Active status, ensuring ongoing availability and supply chain continuity compared to the Obsolete CWB4405CS.

4. Compliance: CW4405CS is RoHS Compliant, providing regulatory alignment for new designs and production environments with RoHS requirements.

5. Manufacturer Continuity: Both parts are manufactured by TE Connectivity Laird, ensuring consistent quality and performance standards.

For applications requiring the CWB4405CS specification, CW4405CS provides full functional and mechanical substitution with the added benefit of active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can CW4405CS be used as a direct replacement for CWB4405CS?

A: Yes. CW4405CS is a direct substitute. All electrical parameters (frequency, gain, VSWR, power rating) and mechanical parameters (dimensions, termination, mounting) are identical. The primary difference is product status: CW4405CS is Active while CWB4405CS is Obsolete.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: center frequency (455MHz), frequency range (440–470MHz), antenna type (Whip, Straight), termination (NMO), mounting type (Base Mount), gain (5dB), VSWR (2), maximum power (200W), and physical height (35.500"). CW4405CS matches all these parameters.

Q: Does packaging differ between CWB4405CS and CW4405CS?

A: Yes. CWB4405CS is packaged as a dash package, while CW4405CS is packaged in Bulk. This distinction does not affect electrical or mechanical performance; it reflects inventory and distribution format only.

Q: Is CW4405CS RoHS compliant?

A: Yes. CW4405CS is RoHS Compliant. RoHS compliance status is not specified for CWB4405CS in the provided data.

Q: Are there any frequency or gain differences between these parts?

A: No. Both parts operate at 455MHz center frequency with a 440–470MHz range and deliver 5dB gain. VSWR and power handling specifications are also identical.

Q: Why is CWB4405CS marked as Obsolete?

A: Product status reflects manufacturer lifecycle decisions. CW4405CS, as the Active equivalent, is the recommended selection for new applications and ongoing production.
