1/4 Wave HF Vertical DX Antenna
My new favorite HF antenna is the 1/4 Wave HF Vertical DX Antenna with 2 Elevated Radials. It is NOT the most portable antenna (an EFHW wins there) but it is the easiest HF antenna to construct! It is easier to construct, install, and tune than even the basic dipole antenna! It takes less than 15 minutes to build and get on the air with this HF DX antenna! No impedance transformer is required. After trimming, the antenna can directly feed 50 Ω coax. A 1:1 common-mode choke (coax choke works too) at the feedpoint is recommended but NOT absolutely required at low power levels. ...
