For those who follow my blog for some time, probably already have an idea that I am really interested in a QRO capable portable vertical antenna. So, last few months I was busy rebuilding a Buddistick type of antenna but I was not able to replicate a usable system for tapping the loading coil. I have to admit, BuddiPole did a clever job with those screw-on coil taps.
Buddipole, here, take my money. I lost the battle, after hours and hours of 3d printing and tinkering.
