Excellently presented test of N9SAB's 20 meter Half Square Antenna by "Outdoors On The Air." While the half square antenna is a bit more complex than a simple random wire or dipole, it does show some gain (around 3dB) broadside over a dipole antenna. In this video, "Outdoors On The Air" assembles, erects, and uses a half square antenna built by N9SAB, and shows the DX capability of this phased vertical array despite being only 20 feet/6.097 meters above ground.
While the antenna can be erected by yourself, you may need some help to make sure the antenna elements are properly supported and aligned. Although the half square can be used in portable operations, it may be best suited for a permanent installation.
Over the past several years, the Big Island Amateur Radio Club (Hawaii Island) has used half square antennas for 80 and 40 meters with excellent results. If you really want 'to push the envelope", have your club build a multi-element sterba curtain array. As a Field Day antenna, the half square and its distant cousin, the sterba curtain, have proven to be reliable DX getters.
