Horizontal Yagi structure (#24)

Yagi Array, No. 4: This model uses the usual equations (129, 130) for the radiated field with the currents for each element taken from a table appropriate for the HF and low VHF frequency bands. The radiation resistance is a free-space approximation. The number of elements may be two or more. Appropriate curves have been devised to design this type of antenna (Uda and Mushiake, 1954). The model implemented here will give valid results for antennas designed this way.
