CN501V VHF/UHF CrossNeedle SWR & Power Meter, 140525MHz, 20/200W, SO239 Connectors, LED-Lit Bench Meter

High sensitivity with SWR detection down to just 4 W, helping you tune antennas even at modest transmit power
Built for stability: 50-ohm impedance with SO239 input/output connectors, anti-slip edge bumpers, and an LED-lit meter (powered via 12V DC)


The CN501V is a value-driven, bench-grade SWR and power meter tailored for VHF and UHF bands. Engineered for device amateurs, repeater builders, and RF technicians alike, the CN501V combines simplicity, reliable performance, and real-world utility all in a compact footprint. At its core is a crossneedle meter that simultaneously displays three critical measurements: forward power, reflected power, and SWR. Unlike meters that require mode switching or separate calibration steps, you can instantly read all three parameters as the two needles cross for SWR. This makes tuning and testing more efficient, particularly during antenna adjustment or performance validation. Covering a frequency range of 140 to 525 MHz, this meter is well-suited for typical VHF/UHF applications such as amateur device, commercial FM, or repeater setups. Its selectable forward power ranges 20 W and 200 W provide flexibility to accurately measure both low-output devices and more powerful transmitters without risking meter overload. For accurate SWR measurements, the CN501V offers sensitivity down to 4 W. This enables you to perform reliable SWR checks even when you're transmitting at relatively low power. The meters input and output ports are matched to 50ohm systems using SO239 connectors, making it compatible with standard coaxial setups. Durability and practicality are built in: the device features anti-slip edge guards to keep it stable on your workbench, and its equipped with a 2.5 mm DC input jack to power the internal LED lighting for the meter perfect for low-light or dimly lit shack environments. Mechanically, the CN501V measures approximately 5 wide × 3 high × 4 deep (about 155 × 80 × 100 mm) and weighs about 1 lb, 8 oz (670 g), making it compact but substantial enough for bench use. Whether you're setting up a new VHF/UHF antenna, adjusting a duplexer, or verifying transmitter output on a repeater system, the CN501V provides the essential measurements you need, with clarity and accuracy, at a value that wont break the bank.
