A wideband 80 meter dipole  ^pop - This worthy antenna is so simple and inexpensive you will want more than one by N6LF

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.

Bruce arrays for 80 and 160m - Antennas with gain and bandwidth for 80 and 160 meters band. Simple wire antenna capable of considerable gain

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.

ICOM 746 Temperature Measurements - The ICOM 746-Pro has acquired a history of NEC 1678G (IC-151) MMIC and driver transistor 2SK2975 failures. The failure of IC-151 appears to be a combination of ESD damage from electrostatic charge on the antenna entering IC-151, and perhaps thermal heat.
