I bookmarked the site - thank you. However, I didn't get very far the first time when I saw the comment "....must be 1/2 wavelength above the ground..."
Still would like to go back and review the entire article. Brings back a humorous dialog from years ago. One ham expressed the desire to build a "....good, but short, 40 meter beam..." It was suggested he shorten the beam until it was ultimately a 50-ohm resistor of sufficient girth to accept reasonable power levels. Chuckles followed. Then, someone who apparently didn't pick up on the tongue-in-cheek, frowned and noted that the 50-ohm resistor would work even better if it was at least a couple wavelengths in the air.
