Spring / Summer backyard tower project
#36
I've had my vertical up and down about 6 times now.  I have worked out a sequence where I can actually do it all by myself without my wife's assistance.  I have a better grasp on how one change in one band influences the other bands.  My most difficult challenge was no resonance for 20M.  What was supposed to be the sweet spot for this band was at 30.306 MHz.

There are four 15" radials for this band.  The manual tells you you only have to trim one.  I found out the hard way the consequences of trimming them ofall.  I started to keep a spreadsheet of my changes and tests which has really aided in fine tuning this.  I still have to change the 20M band 598 KHz to get it where I want which means the antenna comes down one more time.  Here is a sample of my spreadsheet:
