A simple broadband yagi antenna that can be built on a 4 foot boom and used for portable ATV, SSB, or satellite work on the 70-cm band. The antenna design was optimized for broadband performance using YAGIMAX software.
The antenna should be built on a non-conducting boom, such as a wooden ferring strip or dowel. The elements are #10 solid copper wire (with insulation removed). The driven element is matched to a 50 ohm unbalanced feed using a `T' match and a half wavelength coaxial balun.
