    Bruce arrays for 80 and 160m — N6LF
    The Bruce array is a simple, often-forgotten wire antenna array that is advantageous for 80 and 160 meters, where typical gain antennas are very large. This bi-directional broadside vertical array is only 1\4 lambda high and does not require a ground system. It offers substantially greater SWR bandwidth than the half-square or bobtail curtain. A 4-element Bruce array used by N6LF showed a gain of about 4.6 dB compared to a 1\4 lambda vertical with 8 elevated radials, with a 2:1 SWR bandwidth greater than 400 kHz. The antenna is simple and its dimensions are flexible.

    Portable Half-Square Antenna: — WB3GCK
    The author explores a portable version of the half-square antenna, typically a single-band structure. Using a 9:1 unun for versatility, they describe construction with speaker wire, deployment using collapsible poles, and field tests, achieving successful contacts on multiple bands. The article suggests efficient matching methods and concludes with the antenna's integration into the author's portable options.
