The restrictions of the NEC engine are defied here, not only at the connection point of the feeder, but also at the points of the wires intersection.

This conclusion fully applies to this antenna. We have already drawn your attention to the fact that the calculation of microwave antennas in programs based on the NEC engine is not always correct. Double Bi-Quad for HDTV is described in another article. There are several models for Wi-Fi and 3G bands in the archive. The calculation is based on 4NEC2 models of this antenna, the archive of the models can be downloaded from our website. To help with this, the online calculator presented below is intended. Despite the fact that the antenna has a slightly lower gain than 4xQuados, its making is simpler and every who makes Bi-Quad antenna will always have a desire to add two extra squares to it. Let's calculate the Double Bi-Quad antenna.
