CM Centre Fed Linear Loaded Dipole (Cobra Junior) by VK1OD CM CM The Cobra antenna is a linear loaded dipole described by Ray Cook (W4JOH) CM in 73 magazine (June 1997), and gets its name from the "S" configuration CM of the radiator conductors. Two versions were described, this article looks CM at the Cobra Junior which is 22.25m (72') overall, and promoted as an all CM band antenna from 3.5MHz to 30 MHz. CM CM Doubled the number of segments because of length/radius violation (arie).
