I have a tiny city lot ( less than 50' wide) and I want to make a miniG5RV type of dipole, for 10 to 20 meter bands. I have dipole legs of 12' 9'' of hard drawn copper #14, and am making 8' of ladder line. I am using insulated #14 stranded for ladderline, and am making spacers of acrylic. I am using about 9-10 spacers 9-11 inches apart. I am considering building a balun so I can feed coax from the shack out to the antenna. Any suggestions as to how I might make this better ?
