80m with your 66ft end fed half wave.
Thanks to Colin (MM0OPX) for this easy way to convert your 40m-10m antenna into a useable antenna for the 80 meter Amateur Radio Band. According to Colin, the secret to this transformation is the addition of a 110uH coil and a small length of wire at the end of the antenna. Colin shows us how to make this coil and where to position in for the best results.

This is a very inexpensive project which you can make from materials you have lying around. Here is the link to the 66pacific coil inductance calculator. https://www.66pacific.com/calculators...
