Well, there it is, in black and white! I guess my old manual was not
detailed enough, but I figured it out on my own. The 15 meter reflector
acts like a director on 17, but the front-to-back isn't really very much.
BTW, I lived in Hawaii many years ago ('70-'78 KH6HLT) and I know what the
salt air there can do to an antenna. It's probably a good idea to paint
over the non-stainless hardware.
