SteppIR Simulation - Result Overview
Table: Antenna Comparision Overview (Gain, Front/Back)
This page shows the EZNEC simulation results of a 3 Element SteppIR with the optional 6m passive element. Simulation done with fiberglas insulation. Ground type was standard Mininec. Also, I added the values from the Optibeam OB9-5 (as a comparison to the 3 Element SteppIR) beam. In the second part I compared the different SteppIR modes (Standard mode, reversed mode and bi-directional mode).
