Short data for the Yagi at the begin, in the middle part and at the end of the band
Plot with the NEC-II-reference of YO7.23 by K6STI
The meaning of the data :
Frequency, gain, F/R, radiation resistance (impedance), SWR and loss against a theoretical defined maximum- gain-Yagi with the given boomlength. Remember that this gain is only available with very low impedance and extrem low bandwidth! The red line shows the profile of the element currents.
Elementlengths, Radiator always 10mm diameter!
