Building an endfed antenne "the sequel".

Schematic:

For the 40, 20, 15 and 10 meter band, I have shortened the first part of the antenne from 20.40 meters to 20.15 meters.

I have also decreased the coil value from 120 to 90 uH in combination with a longer extension of the 80 meters part at the end, this gives a better bandwidth on 80 meters.


Measuring results:


80 meters 40 meters







20 meters 15 meters


10 meters Minimum SWR








SWR curve 80 meters


SWR curve 40 meters


SWR curve 20 meters


SWR curve 15 meters


SWR curve 10 meters
