ETA MRT validates the knowledge microwave technicians need to safely install, align, operate, and fundamentally maintain point-to-point microwave radio systems. ETA suggests prior experience with radio systems and equipment.
ETA Press lists MRT as a stand-alone certification with maintenance required, a 4-year term, no hands-on requirement, 75 questions, a 75% passing score, and 2 hours allowed to test.
Study RF microwave safety, non-ionizing versus ionizing radiation, exposure standards, PPE, tower safety, grounding hazards, FCC/NTIA/ITU roles, frequency, amplitude, wavelength, bandwidth, gain, attenuation, noise, dB, dBm, dBv, and 3-dB/6-dB/10-dB rules.
Preparation should include point-to-point microwave equipment, antennas and transmission lines, multiplexing, heterodyning, modulation, quadrature signals, coding and decoding, interference and channel protection methods, performance indicators, timing, synchronization, alignment, maintenance, and test equipment.

ETA Microwave Radio Technician (MRT) is an ETA International certification for technicians working with point-to-point microwave radio systems used in radio, data, carrier backhaul, and public-safety communications. ETA describes the credential as covering the knowledge needed to install, align, maintain, and operate microwave radio systems, with prior radio systems experience suggested.
ETA Press lists MRT as a stand-alone certification with maintenance required, a 4-year term, no hands-on requirement, 75 questions, a 75% passing score, and 2 hours allowed to test. Preparation should cover RF microwave safety, non-ionizing radiation, maximum permissible exposure, PPE, tower and elevated-surface safety, grounding hazards, FCC/NTIA/ITU roles, radio spectrum concepts, frequency, amplitude, wavelength, bandwidth, gain, attenuation, noise, multiplexing, heterodyning, modulation, quadrature signals, CODECs, decibel math, dBm and dBv, antenna and transmission fundamentals, microwave equipment, interference and channel protection, performance indicators, timing and synchronization, and common microwave test equipment.
ETA Microwave Radio Technician (MRT) is a stand-alone ETA International credential for technicians who install, align, maintain, and operate point-to-point microwave radio systems.
ETA Press lists the MRT exam at 75 questions with 2 hours allowed to test.
ETA Press lists a 75% passing score for the Microwave Radio Technician certification.
No. ETA Press lists no hands-on requirement for MRT, though the credential is written for technicians who understand microwave radio field work.
Study RF microwave safety, radio-site hazards, exposure limits, spectrum and frequency concepts, dB math, modulation, multiplexing, antennas, transmission fundamentals, interference and channel protection, timing, synchronization, alignment, maintenance, and microwave test equipment.
Be able to identify RF hazards, read site signage, explain exposure limits, choose PPE, and describe tower, elevated-surface, and grounding safety controls.
Review absolute versus relative dB, dBm, dBv, milliwatts, voltage ratios, and the common 3-dB, 6-dB, and 10-dB power or voltage rules.
Tie frequency, bandwidth, gain, attenuation, noise, modulation, multiplexing, and antenna behavior to actual point-to-point microwave link performance.
Study interference identification, channel protection, performance indicators, timing and synchronization schemes, and what test equipment readings reveal.
Practice a workflow for install, alignment, operation, maintenance, troubleshooting, documentation, and escalation for microwave radio systems.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
