Cable & Antenna Analyzers

Cable and antenna analyzers are specialized instruments used to evaluate the performance and integrity of transmission lines, coaxial cables, and antenna systems. By transmitting a test signal through the device under test, these analyzers measure key parameters including voltage standing wave ratio (VSWR), return loss, insertion loss, impedance, cable loss, and distance-to-fault (DTF). They are indispensable tools for field technicians and RF engineers who need to verify antenna installations, identify faults, and optimize signal transmission performance.

Available in both handheld and benchtop form factors, cable and antenna analyzers are widely used in telecommunications for base station commissioning and maintenance, in aerospace and defense for antenna system verification, and in broadcasting for transmission line inspection. Handheld models are especially valued for field work due to their portability, long battery life, and rugged construction.

Typical Applications

Telecom base station antenna commissioning and maintenance, verifying VSWR and return loss compliance against carrier specifications
Transmission line fault location using distance-to-fault (DTF) measurements in cellular, broadcast, and satellite networks
Passive intermodulation (PIM) testing to identify interference sources in LTE, 5G NR, and UMTS antenna systems
Aerospace and defense antenna system verification and field maintenance on ground and airborne platforms
Cable loss and impedance characterization for RF system integration in electronics manufacturing and R&D laboratories
