V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Protocol Mismatch: 3G (UMTS) devices using GSM single-band antenna → Choose dual-band antenna (2313371) for GSM/UMTS compatibility.
2. Interface Incompatibility: USB controllers using RS232-only modem → Select USB cable (2313575) or RS232-to-USB adapter for connectivity.
3. Antenna Form Factor Mismatch: Outdoor deployment using stub-type antenna → Opt for QB-type (2313371) for omnidirectional signal reception.
4. Cable Length Underestimation: 8m antenna extension using 5m cable → Choose 10m variant (2900981) to avoid signal loss from stretched cables.
5. Functionality Neglect: Fax communication needs using basic data modem → Select Data/Fax modem (2708203/2708253) for fax support.
6. Industrial Environment Neglect: Outdoor use using non-weather-resistant antenna → All PSI antennas are weather-resistant; QB-type (2313371) is optimized for outdoor deployment.
7. Modem-Antenna Compatibility: QB antenna using non-QB-compatible modem → Ensure modem has QB suffix (2313106) for QB antenna compatibility.
8. EMI Interference: High-noise environments using unshielded cables → PSI cables feature industrial-grade shielding for EMI suppression.
