U20466 Used Daiwa CN-501V Cross Needle SWR/Wattmeter VHF/UHF 200W

U20466 Used Daiwa CN-501V Cross Needle SWR/Wattmeter VHF/UHF 200W

Overall Condition: Used, great physical and operational condition overall showing normal, careful shack use! Cosmetic Details: The dark teal-blue painted metal casing is clean throughout, with faint superficial scratches on the side panel as its primary cosmetic note. The protective black rubber impact end-caps are fully intact, flexible, and free of dry rot or tears. Meter & Faceplate: The illuminated cross-needle meter movement and clear acrylic display lens are exceptionally clean, bright, and easy to read, with sharp factory graphics. Switches & Operation: Front latching push-buttons for power ranges (20W / 200W / OFF) and the AVG / PEP function selector switch actuate crisply with positive tactile feedback. Rear Panel & Connectivity: Rear SO-239 coaxial jacks for ANT OUTPUT and TR INPUT feature bright, clean threads and undamaged white dielectric insulators. The 13.8V DC lighting power jack is firm and clean. Complete with a dedicated DC power cable with barrel connector for internal dial illumination.

The Daiwa CN-501V is a dedicated VHF/UHF cross-needle RF power and standing wave ratio meter covering the 140 through 525 MHz frequency range (encompassing 2M, 1.25M, and 70cm amateur bands). Designed with Daiwa’s simultaneous cross-needle movement, forward power, reflected power, and SWR are displayed concurrently at the exact crossing point of the dual needles—eliminating the need for manual sensitivity calibration or forward-to-reverse switching.

Rated for power inputs up to 200 Watts, the CN-501V offers two selectable power scales (20 Watts for handhelds/QRP and 200 Watts for standard mobile and base station transceivers). Featuring switchable Average (AVG) and Peak Envelope Power (PEP) modes, removable ribbed rubber benchtop protective bumpers, and low insertion loss, it is an essential monitor for VHF/UHF repeaters, satellite operating, and weak-signal base stations.

Condition Breakdown

• General: Pre-owned, solid mechanical, cosmetic, and RF operational condition

• Meter Face & Display: Cross-needle meter movement is pristine; clear acrylic cover is clean and free of deep scratches, cracks, or haze

• Cabinet & End Guards: Heavy steel chassis is straight and dent-free, displaying faint cosmetic scratches on the side panel; textured rubber corner protectors fit snugly

• Front Controls: Front push-buttons (20W / 200W / OFF range and AVG/PEP selector) latch and release smoothly

• Rear Connectors: ANT OUTPUT and TR INPUT SO-239 coaxial receptacles are firm, clean, and oxidation-free; 13.8V DC power port is solid

• Included Wiring: Comes with a new DC power lead terminated with the correct barrel plug for the internal meter lamp

Key Features

• 140 to 525 MHz VHF/UHF Coverage: Continuous frequency coverage covering 2 Meters, 1.25 Meters, and 70cm amateur bands

• Simultaneous Cross-Needle Readout: Displays Forward Power, Reflected Power, and SWR simultaneously where needles cross without calibration steps

• 20W & 200W Selectable Ranges: Low-scale (20W) provides expanded resolution for HTs and QRP rigs; high-scale (200W) handles mobile and base station gear

• Selectable PEP / AVG Modes: Accurately measures Peak Envelope Power for SSB or average power for FM, CW, and digital modes

• Illuminated Dial Scale: Built-in lighting illuminates meter markings for easy low-light shack viewing (requires external 13.8V DC source)

• Protective Rubber Edge Bumpers: Rugged surround guards absorb bench bumps and keep the meter from sliding across operating surfaces

• Low Insertion Loss: High-quality stripline directional coupler ensures negligible insertion loss across VHF and UHF bands

What's Included

• Daiwa CN-501V VHF/UHF Cross-Needle SWR/Power Meter Unit

• 13.8V DC Meter Illumination Power Lead (Barrel Plug to Bare Wire Leads)
