TRAT2100 RF Antenna 217MHz Dome NMO Base Mount - Equivalent & Substitute Parts

Part Overview

The TRAT2100 is a 217MHz dome RF antenna manufactured by TE Connectivity Laird, designed for VHF applications within the 210MHz to 225MHz frequency range. This antenna features a 5dBi gain, NMO base mount termination, and is rated for 60W maximum power. The TRAT2100 is classified as obsolete, making identification of active equivalent parts essential for procurement and system continuity. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure seamless integration into existing RF systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TRAT2100 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Center frequency: 217MHz
• Operating frequency range: 210MHz – 225MHz
• Antenna type: Dome configuration
• Gain: 5dBi
• VSWR: 2
• Return loss: -10dB
• Maximum power handling: 60W

Mechanical Parameters (Non-negotiable):

• Termination type: NMO connector
• Mounting configuration: Base Mount
• Physical height: 3.500" (88.90mm) maximum

Compliance Parameters:

• RoHS Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)

The TRABT2100 qualifies as a direct substitute because it maintains identical electrical performance across all RF parameters, identical mechanical configuration, and identical compliance certifications. The primary distinction is product status (Active vs. Obsolete) and packaging format (Bulk vs. standard packaging).

Engineering Selection Recommendations

Primary Substitute: TRABT2100

The TRABT2100 is the direct equivalent for the obsolete TRAT2100. Selection of TRABT2100 is based on the following engineering criteria:

1. Electrical Equivalence: All RF parameters (frequency, gain, VSWR, return loss, power rating) are identical across both parts.

2. Mechanical Compatibility: NMO termination, base mount configuration, and physical dimensions are identical, ensuring drop-in compatibility with existing installations.

3. Product Status: TRABT2100 maintains Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete TRAT2100.

4. Compliance Certification: Both parts maintain identical RoHS Compliance and MSL ratings, satisfying regulatory and handling requirements.

5. Packaging Consideration: TRABT2100 is supplied in Bulk packaging. Organizations requiring standard packaging formats should confirm packaging availability with the supplier.

6. Inventory Availability: TRABT2100 has 742 pieces in stock, providing immediate procurement capability.

No alternative substitutes are provided in the reference data. Any deviation from the specified electrical or mechanical parameters would result in incompatibility with the original system design.

Frequently Asked Questions (FAQ)

Q1: Can TRABT2100 be used as a direct replacement for TRAT2100 in existing RF systems?

A: Yes. TRABT2100 is electrically and mechanically identical to TRAT2100 across all critical parameters: frequency range (210–225MHz), gain (5dBi), VSWR (2), return loss (-10dB), NMO termination, base mount configuration, and physical dimensions. It functions as a direct drop-in substitute.

Q2: What is the primary reason for substituting TRAT2100?

A: TRAT2100 is classified as Obsolete, which creates supply chain risk and potential discontinuation. TRABT2100 is Active status, ensuring continued availability and long-term procurement reliability.

Q3: Are there any electrical performance differences between TRAT2100 and TRABT2100?

A: No. Both parts are specified identically for all RF parameters: center frequency (217MHz), operating range (210–225MHz), antenna type (Dome), gain (5dBi), VSWR (2), return loss (-10dB), and maximum power (60W).

Q4: Does packaging format affect electrical or mechanical performance?

A: No. TRABT2100 is supplied in Bulk packaging while TRAT2100 uses standard packaging. Packaging format does not affect antenna performance, electrical characteristics, or mechanical compatibility. Confirm packaging requirements with procurement before ordering.

Q5: Are both parts RoHS Compliant?

A: Yes. Both TRAT2100 and TRABT2100 are RoHS Compliant with MSL rating of 1 (Unlimited), satisfying identical regulatory and environmental requirements.

Q6: What is the NMO termination, and is it compatible with standard RF connectors?

A: NMO (N-type Mobile Connector) is a standardized RF connector type. Both parts use identical NMO termination, ensuring compatibility with NMO-equipped RF systems and cabling.

Q7: Can TRABT2100 be used in applications requiring the exact same physical footprint as TRAT2100?

A: Yes. Both parts have identical maximum height of 3.500" (88.90mm) and identical base mount configuration, ensuring compatibility with space-constrained installations.

Q8: Is there any performance degradation when substituting TRAT2100 with TRABT2100?

A: No. TRABT2100 maintains identical electrical performance specifications across all measured parameters (gain, VSWR, return loss, frequency response, power handling).
