This 2 elements yagi antenna is intended for the 70cm UHF band center frequency is 410Mhz with 10Mhz bandwidth. The antenna measurements are computed and then simulated on 4Nec2 antenna modelling software.
Measure and cut the boom according to the diagram and assemble the antenna following the antenna construction technique here. Of course you may improvised and follow your own construction technique the goal of the video is to help you visualize the technique I’ve used to build this antenna successfully – but everything is not set in stone.
Note: You may have downloaded a wrong copy of the diagram that sets the spacing to 30.2cm – that is incorrect sorry my mistake I uploaded a wrong version of the diagram when I initially uploaded the article. It has now been corrected with the diagram below.
Here’s the antenna frequency response and tuning video on my Youtube Channel
