QWB152-L RF Antenna Equivalent & Substitute Parts

Part Overview

The QWB152-L is a 157MHz center frequency whip antenna manufactured by TE Connectivity Laird, designed for VHF applications in the 152MHz to 162MHz frequency band. This straight whip antenna features an NMO base mount termination and delivers 0dB gain with a VSWR of 2. The unit measures 18 inches in height and is classified as obsolete. Due to its obsolete product status, identification of equivalent and substitute parts is necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QWB152-L is determined by strict equivalence across the following critical parameters:

Frequency Compatibility: The substitute part must operate within or encompass the 152MHz to 162MHz frequency band with a center frequency of 157MHz.

Antenna Configuration: The substitute must be a whip antenna with straight orientation to maintain mechanical and electrical compatibility with existing mounting infrastructure.

Termination Type: The NMO base mount termination is mandatory for direct mechanical and electrical compatibility.

Electrical Performance: VSWR of 2 and 0dB gain establish the baseline performance envelope for acceptable substitutes.

Physical Dimensions: The 18-inch height specification must be maintained to ensure proper radiation pattern and system integration.

Compliance Requirements: RoHS compliance and MSL rating of 1 must be preserved.

Based on the provided input data, the QWB152-L is listed as its own substitute with identical specifications across all parameters.

Engineering Selection Recommendations

The QWB152-L is classified as an obsolete product. Current inventory of 1156 pieces is available as new original stock. For applications requiring this specific antenna, the QWB152-L remains the direct equivalent part with full parameter alignment.

Selection of this antenna is appropriate for VHF systems operating in the 152MHz to 162MHz band where NMO base mount termination and 18-inch whip configuration are specified. The RoHS compliance status and MSL rating of 1 satisfy environmental and handling requirements for standard storage and deployment conditions.

Frequently Asked Questions (FAQ)

Q: Can the QWB152-L be substituted with antennas from other manufacturers?

A: Substitution with parts from other manufacturers is possible only if the alternative part meets all specified parameters: 152MHz to 162MHz frequency range, whip straight antenna type, NMO termination, 18-inch height, VSWR of 2, 0dB gain, and RoHS compliance. Direct equivalence across all parameters is required.

Q: What does the obsolete product status mean for procurement?

A: Obsolete status indicates the QWB152-L is no longer in active production. However, 1156 pieces of new original stock are currently available. For long-term supply assurance, alternative antenna models meeting the specified parameters should be evaluated.

Q: Is the NMO termination critical for substitution?

A: Yes. The NMO base mount termination is a mandatory parameter for mechanical and electrical compatibility. Substitutes must use identical NMO termination to ensure proper installation and performance.

Q: What is the significance of the 18-inch height specification?

A: The 18-inch height directly affects antenna radiation pattern, impedance matching, and system performance at 157MHz. Substitutes must maintain this dimension to preserve electrical characteristics and mechanical fit within the host system.

Q: Does MSL rating 1 affect storage or handling requirements?

A: MSL rating 1 indicates unlimited moisture sensitivity, meaning standard storage conditions without special humidity control are acceptable. No special handling or baking procedures are required prior to installation.

Q: Can frequency range variations be accommodated?

A: No. The 152MHz to 162MHz frequency range with 157MHz center frequency is a critical parameter. Substitutes operating outside this band will not provide equivalent performance and are not acceptable.
