The ZFGL 20W QRP Portable Antenna & Tuner (also widely known under the WuKong365 brand) is a highly portable, all-in-one low-power shortwave antenna and manual tuning unit designed for minimalist field operations. By combining a base-loaded matching circuit with a telescopic whip antenna, operators can transmit and receive across a wide frequency range without the need for heavy coax cables or large wire arrays.
⚠️ Critical Operation Warnings
Mandatory Ground Wire (Counterpoise): The small knurled lug nut and copper tab located on the top antenna output side is the ground terminal. You must attach a radial/counterpoise wire (approximately 33 feet or 10 meters) to this copper clip for the antenna to radiate properly on HF bands. Without a ground wire attached, the tuner will act as a dummy load, resulting in deaf reception and poor transmission.
Strict 20W Power Limit: This tuner is rated for a strict 20 Watts maximum RF input. Transmitting with higher power will arc the internal capacitor and permanently destroy the tuning circuit.
ℹ️ Factory Revision Disclaimer
Due to ongoing factory revisions, your device's branding (e.g., labeled as "ZFGL." instead of "WuKong365") and physical output connector (e.g., a threaded antenna post instead of a BNC jack) may vary slightly from standard stock photography. The core operating principles, performance, and internal components remain identical across these aesthetic batches.
Performance & Engineering Highlights
-
📻Broad Frequency Coverage Capable of tuning the 3.5-30 MHz (HF) and 50-54 MHz (6-Meter) bands for transmission. Additionally provides receive capabilities on 76-108 MHz (FM), 117-136 MHz (Airband), 136-174 MHz (VHF), and 400-470 MHz (UHF).
-
🔌Direct-Mount Design The PL-259 (UHF Male) connector located on the bottom of the unit is designed to plug directly into the SO-239 antenna jack on the back of portable radios, eliminating feedline loss.
-
🎛️Intuitive Manual Tuning Features a multi-position rotary band selector switch to tap the internal coil, and a continuous main tuning knob (scaled 1-7) to sweep the variable capacitor for an optimal SWR of ≤1.5:1.
-
🎒Ultralight Form Factor Housed in a rugged black aluminum extrusion, the entire tuning unit weighs only 170g, making it a perfect addition to QRP go-bags.
