MFB4503

Antennas RF Overview

The Amphenol PCTEL MFB4503 is a UHF omnidirectional whip antenna designed for the 450-460 MHz frequency range. It features a fiberglass construction with a straight form factor and N-type male connector. The antenna provides 3 dBi gain, operates at a nominal impedance of 50 Ohms, and supports a maximum power rating of 250 Watts. Key electrical specifications include a VSWR of 1.5:1 and a bandwidth of 10 MHz. It utilizes wall mount installation and includes a 16-inch pigtail.

Antennas RF Feature Summary

• Omnidirectional radiation pattern for uniform signal coverage
• Fiberglass housing for durable outdoor environmental resistance
• Integrated 16-inch pigtail with N-type male connector for flexible cabling

Antennas RF Applications

• UHF base station installations
• LoRa network infrastructure
• LPWAN connectivity systems
• ISM band communication applications

Antennas RF Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and mounting hardware requirements. Ensure compatibility with existing N-type male connectors in the RF chain. Confirm that the 250-watt power rating aligns with the transmitter output specifications for the intended deployment environment.

Antennas RF Selection Notes

Select this model when an omnidirectional solution is required within the 450-460 MHz band. The 3 dBi gain offers standard coverage without high directivity. Consider the wall mount style and included pigtail length during system design to ensure adequate cable routing flexibility compared to fixed-length or pole-mount alternatives.

Antennas RF Part Context

This component belongs to the MFB series of industrial IoT antennas from Amphenol PCTEL. It targets general ISM and LPWAN applications requiring robust UHF performance. The product status is active, indicating ongoing manufacturing support and availability for new designs in wireless communication networks.

Antennas RF Replacement Considerations

The MYA4503N is a directional Yagi alternative offering higher gain (9.2dBi) but requires bracket mounting and lacks the integrated pigtail. Verify if the application demands omnidirectional coverage versus directional focus before substituting.
