• Coaxial Collinear Antenna for 70 CM Band - This coaxial collinear antenna was built to test for my own consumption whether or not this antenna method actually works. the guiding principle is that we have multiple 1/4 wave elements fed in series , the radiation from each adds in phase to produce a large vertically polarised omni-directional antenna with substantial gain

• Horizontal Loop Antenna Experiments - The HF horizontal loop has been around for many years now. This article includes a YouTube video and discusses the reasons for looking at this antenna, its design, and its installation. There are some on-air comparisons against three regular double bazooka (coax) dipoles and the Par SWL End-Fed antenna.
