Building A Full-Wave Quad Loop Antenna for 6 Meters

This is an easy antenna to build and the materials cost about $15-20.  It exhibits 1.8dB gain over a 1/2-wave dipole.  Using an open-wire parallel feedline (commonly called “ladder line”) with an antenna tuner, it tunes up on the 10m band as a 5/8-wave loop as well.  The loop is also much quieter than a…
