Using the half-square antenna for low bands - Can’t put up a really high horizontal antenna for 80-meter DXing? Maybe the vertically polarized Half-Square might be the antenna for you.

Broadbanding the half-square on 80 meters - N6LF discusses a simple way to broadband the classic half-square antenna to operate in both the CW and SSB DX windows on 80/75 meters.

CobWebb multiband folded dipole - It is basically a 5 band antenna comprising of 5 full half wave dipoles for each band - between 10M & 20M, the antenna is also resonant on 6M

An improved 40-80 double extended zepp - Article originally published in ARRL compendium by N6LF revisits the classic double extended Zepp to improve pattern and SWR bandwidth. The DEZepp is essentially two end-fed collinear dipoles.

Making a half wave coax cable - How to make a half l or quarter l coax cable for a specific frequency

Remotely-tuned loop antenna for LW and MW - This article describes how to build a loop antenna for low frequency (LF) and medium wave (MW) reception with remote-controlled tuning. The antenna is extremely sensitive and can be built mostly from parts from old radios and tape recorders. Like all loop antennas, it is highly directional, which allows you to null out unwanted noise sources.
