U20419 Used LnR Precision EFT-10/20/40 QRP End-Fed Half Wave (EFHW)  Antenna

Overall Condition: Used, good physical condition overall showing light signs of outdoor field deployments! Matchbox & Hardware: The weather-sealed matchbox enclosure, product label (EFT-10/20/40 QRP), BNC connector, and wire strain relief eyelets are solid and intact. Radiator Wire & Coax: The black radiator wire, inline loading coil/stub, wire winder, and RG-174 coaxial feedline cable with BNC connectors show normal, light handling wear with no breaks or insulation damage.

The LnR Precision EFT-10/20/40 QRP (Trail Friendly / Par EndFedz design) is a highly efficient, multi-band End-Fed Half-Wave (EFHW) wire antenna system engineered for QRP low-power portable operations, Parks on the Air (POTA), Summits on the Air (SOTA), and stealth field operating. It provides resonant, low-SWR operation across the 40M (7 MHz), 20M (14 MHz), and 10M (28 MHz) amateur bands without requiring an external antenna tuner.

Featuring a high-efficiency impedance matching transformer housed in a compact matchbox, a lightweight stealth radiator wire with inline loading network, and a flexible RG-174 coaxial feedline, the EFT-10/20/40 can be easily deployed in sloper, inverted-V, horizontal, or vertical field configurations.
