The following figures were measured on the testing range using the protocol set forth in “Antenna Comparison Reports – HF Tri-Banders” by Ward Silver (N0AX) and Steve Morris (K7LXC). For those unfamiliar with the technique this uses measurements of real antennas across a salt laek, with yagis referenced to a physical half-wave dipole at the same height.
