Antenna have been calculated using state of the art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns and connectors. The performance of the antenna designed using these techniques are exceptional, far better than any antennas designed using “wire” programs like EZNEC Pro/4 – NEC v5.0, 4NEC2, MMANA or AO.
