CB34 RF Antenna 36MHz Whip Straight NMO Base Mount - Equivalent & Substitute Parts

Part Overview

The CB34 is a 36MHz center frequency whip antenna with straight configuration and NMO base mount termination, designed for VHF applications in the 34MHz to 37MHz frequency range. Manufactured by TE Connectivity Laird, this component delivers 0dB gain with a VSWR of 2 and operates across a maximum height of 52.500 inches (133.35cm).

The CB34 carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain system continuity, ensure procurement availability, and support ongoing field deployment and maintenance operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB34 is determined by strict alignment across the following critical parameters:

Frequency Compatibility: Center frequency of 36MHz with operational range 34MHz to 37MHz Antenna Configuration: Whip, straight form factor Termination Standard: NMO base mount connector Electrical Performance: 0dB gain and VSWR of 2 Physical Dimensions: Maximum height of 52.500 inches (133.35cm) Compliance Requirements: RoHS Compliant status

The substitute part C34 satisfies all these criteria, maintaining identical electrical and mechanical specifications while differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The C34 serves as a direct functional equivalent to the CB34. Both components are manufactured by TE Connectivity Laird and maintain identical electrical performance specifications, mechanical dimensions, and compliance certifications.

The primary distinction is product lifecycle status: CB34 is classified as Obsolete, while C34 maintains Active status. This status difference indicates C34 availability through current distribution channels and ongoing manufacturer support.

Both parts carry RoHS Compliant certification and meet the same regulatory requirements for VHF antenna applications. The C34 is available in Bulk packaging, whereas CB34 packaging designation is not specified.

For new designs or system replacements, C34 is the appropriate selection. For legacy system maintenance where CB34 inventory exists, existing stock may continue to be deployed until exhausted, after which transition to C34 is required.

Frequently Asked Questions (FAQ)

Q: Can C34 replace CB34 in existing installations?

A: Yes. C34 and CB34 are electrically and mechanically identical across all specified parameters: frequency range (34MHz ~ 37MHz), antenna type (whip, straight), termination (NMO base mount), gain (0dB), VSWR (2), and physical dimensions (52.500" maximum height). Direct substitution is supported.

Q: What is the difference between CB34 and C34?

A: The components are functionally equivalent. CB34 is classified as Obsolete, while C34 maintains Active product status. C34 is packaged in Bulk configuration. All electrical and mechanical specifications are identical.

Q: Why is CB34 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. C34 represents the current active equivalent for continued procurement and deployment.

Q: Are there inventory considerations when selecting between CB34 and C34?

A: CB34 inventory is reported at 657 pieces. C34 inventory is reported at 648 pieces. Both are available as new original stock. Selection should prioritize C34 for new procurements due to its Active status and ongoing manufacturer support.

Q: Does packaging affect electrical performance?

A: No. Packaging configuration (Bulk for C34 versus unspecified for CB34) does not affect electrical or mechanical performance. Packaging impacts logistics, storage, and handling only.

Q: Are both parts RoHS compliant?

A: Yes. Both CB34 and C34 carry RoHS Compliant certification and meet the same environmental and regulatory standards.
