Overview
The 158-4H-MK is a heavy-duty Yagi antenna designed for the VHF band, manufactured by Antenna Technologies Limited Company. It operates within a frequency range of 152MHz to 157MHz, with a center frequency of 155MHz. The unit features a 4-element configuration and provides a gain of 7dBi. It utilizes an N-type female connector interface. The antenna maintains a Voltage Standing Wave Ratio (VSWR) of 1.2, ensuring efficient signal transmission. This model is part of the RF-Antennas category and is RoHS compliant.
Feature Summary
- Heavy-duty construction optimized for VHF band operations
- Four-element Yagi design for directional signal reception
- Low VSWR rating for efficient power transfer
- Standard N-type female connector interface
Applications
- VHF radio communication systems
- Directional signal reception in the 152-157MHz range
- Fixed point-to-point wireless links
- Industrial monitoring applications requiring robust antennas
Procurement Notes
Verify the specific datasheet version from Antenna Technologies Limited Company before procurement. Confirm mechanical dimensions and mounting requirements match the installation site. Ensure the N-type female connector compatibility with existing cable assemblies. Check for any regional regulatory compliance requirements beyond RoHS standards applicable to the deployment location.
Selection Notes
Select this model when a directional high-gain solution is required for the 155MHz center frequency. The 4-element Yagi structure offers improved directivity compared to omnidirectional alternatives. Consider the heavy-duty build quality for outdoor or harsh environment deployments. Verify that the 7dBi gain meets the link budget requirements for the intended application distance.
Part Context
This component belongs to the RF-Antennas category, specifically within the Yagi antenna sub-segment. It is engineered for fixed installations where directional gain is prioritized over coverage area. The product line focuses on reliable performance in the VHF spectrum, supporting various industrial and commercial communication needs through standardized interfaces.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. When replacing this unit, ensure the new component matches the 152-157MHz frequency range and 7dBi gain specifications. Verify that the replacement also features an N-type female connector and compatible mechanical mounting dimensions.
