It is resonate for 22 Mhz haven't had any luck tuning it for 30 Mhz it is an excellent antenna I feel at the Z is 0 for 22 Mhz I have given up and think I will just buy a Imax 2000 w/ radials??
"10 meter" I attempted to build a 1/4 antenna with 8 ground radials 4 feet long with 1/4 wave length of copper coiled around them and are sloped down 55 degrees
