Mcbazel Surecom SW-102 Digital VHF/UHF 125-525Mhz Antenna Power & SWR Meter
Quick take
The Mcbazel Surecom SW-102 is a digital SWR and antenna power meter for VHF/UHF use (125-525 MHz), designed to help you tune antennas and verify forward and reflected RF power. It reads SWR directly and is positioned for amateur radio-style setups where CW, AM, and FM are used, with a practical low-insertion-loss design for inline testing. The main caveat is compatibility: it does not work with DMR-style digital radio and it cannot measure RTTY or SSB.
Pros and cons
Pros
- Digital forward/reflected power and SWR readouts, which helps during antenna matching and troubleshooting.
- Wide coverage for VHF/UHF tuning needs, spanning 125-525 MHz, with useful focus on common VHF/UHF ham ranges.
- Maximum measurable power up to 120W, suitable for many typical antenna tuning scenarios.
- Includes N-Type female ports with adapters, so it can connect to common ham gear setups that use N-Type to SO-239 style connections.
Cons
- Not compatible with digital radio types such as DMR, and it only measures CW, AM, and FM (not RTTY or SSB).
- Connector compatibility depends on your radio and antenna ports, and extra third-party adapters may be required if you do not use N-Type or SO-239.
- Frequency coverage is broad, but it is not meant for CB (27 MHz) use, so it will not replace a CB-specific meter.
What buyers think
Buyer feedback is generally positive, with the strongest recurring themes centered on usability and confidence during tuning. Many users describe the readouts as clear and helpful for comparing antenna setups, and a number of reviewers say the meter performs accurately for VHF and UHF work within their intended range. Several comments also highlight that it is straightforward to operate, making it useful both for people setting up new radios and for those doing routine antenna checks in the field.
There is limited evidence in the available reviews about deeper measurement behavior outside the meter’s intended mode and band support, so performance expectations should stay within VHF/UHF use cases that match its supported signal types.
Key features that matter for antenna tuning
Digital SWR plus forward and reflected power
Instead of relying on analog-style interpretation, this meter provides direct digital readouts for SWR and RF power measurements. In practical terms, that gives you both the mismatch indicator (SWR) and the power relationship between forward and reflected components, which can make it easier to spot when an antenna is not properly matched.
Built for VHF/UHF coverage, with a power ceiling
The unit supports 125-525 MHz operation and is engineered for strong usefulness in common VHF and UHF amateur-style bands. It’s also specified for maximum measurable power up to 120W, which helps ensure it can handle a lot of typical tuning scenarios without immediately running into a low power limit.
Low insertion loss for inline testing
Low insertion loss (0.3 dB or less) is intended to reduce how much the meter changes the signal when it’s connected inline. That matters because tuning and verification tools are most helpful when they do not significantly alter what you are trying to measure.
Connections and included adapters
The meter uses N-Type female connectors and includes adapters for N-Type to SO-239 connections. If your radio or antenna uses different connector types (such as BNC, SMA, PL-259, or TNC), plan on using appropriate third-party adapters, since they are not included.
Compatibility limits to check before you buy
- Digital radio compatibility: it is not compatible with digital radio such as DMR.
- Supported modulation types: it can measure CW, AM, and FM only, and it cannot measure RTTY or SSB.
- Band limitations: it is intended for VHF/UHF work and is not for 27 MHz CB use.
- Ground plate: the design notes that a ground plate is not included, which can matter for certain testing setups.
Pros and cons for real-world buyers
Who it’s best for
- Ham radio operators and hobbyists tuning antennas on VHF/UHF frequencies within 125-525 MHz.
- People who want an easy-to-read digital SWR and power meter for routine checks and setup optimization.
- Users who mainly transmit in CW, AM, or FM and do not need RTTY or SSB measurements.
Who should consider a different option
- If your radio workflow is based on DMR or you need compatibility with digital voice protocols, this meter is not the right match.
- If you require RTTY or SSB measurements, you will likely be disappointed.
- If your gear uses connector types beyond N-Type/SO-239, you may need extra adapters, which adds cost and complexity.

Bottom line
The Mcbazel Surecom SW-102 is a practical digital SWR and antenna power meter for VHF/UHF users who transmit in CW, AM, or FM. It stands out for its straightforward digital readouts and usefulness for tuning and verification in its intended band range. Just make sure your radio type and signal modes fall within its supported compatibility, because DMR and some modulation types are explicitly not supported.
FAQ
