Design Criteria: Simple wire antenna;Cheap to make, using readily available materials;Low angle radiation, with rejection of high angle signals;Wide bandwidth, with resonance at the 80M DX window (3.790-3.800 MHz); andMaximum height is 40 feet (limitation due to treeheight). Design:Since the use of a full ¼-wave vertical was out of the question because of space reasons,…
