80-10m EFHW
Description
This 80-10m End-Fed Half-Wave (EFHW) antenna was my first HF antenna installation after obtaining my amateur radio license in April 2025. It is a ready-made, commercially purchased 8-band version that covers the 80, 40, 30, 20, 17, 15, 12, and 10 meter bands.
The EFHW design offers several advantages for a first HF antenna: it requires only a single support point, can be deployed in various configurations (horizontal, sloper, or inverted-L), and typically operates without requiring an antenna tuner across its design bands. This makes it an excellent choice for getting on the air quickly while learning HF operations.
This antenna is fed with Messi & Paoloni Ultraflex 2 coax, the single coax type used across all outdoor runs on this station.
