No-Tune End Fed Half Wave Antenna Module 50Ω 10W PCB
No-Tune End Fed Half Wave Antenna Module – 50 Ohms | 10W | Portable PCB Assembly
The No-Tune End Fed Half Wave (EFHW) Antenna Module is a compact, ready-to-use PCB assembly designed for amateur radio operators and RF enthusiasts who want a hassle-free, no-tune antenna solution. With a matched 50-ohm impedance output, this module connects directly to standard coaxial feedlines without the need for an additional antenna tuner — saving you time and effort in the field or at home.
Built on a high-quality 1.6mm double-sided PCB with full tinning process, this module delivers reliable performance for both low and high current applications. Its one-piece molded design ensures a smooth, burr-free surface and straightforward installation. The large heat-dissipation area keeps the module running stably over extended operating sessions — ideal for portable or field-day setups.
