One of the most inexplicable fads are these ridiculous flags flying from porches, pillers, balcony's, and decks. They show everything from a frog to a pineapple. Neighbors won't be any the wiser. Dig the guy who was asked why he was burying chicken wire at his new fancy home, before the lanscaping folks brought in several truckloads of topsoil. I think it should be grandfathered or something.
Nothing beats a good rain gutter.
A piece of wire laying on your roof is real hard to spot as well. I found the book on Stealth ham radio by the ARRL to be helpful. On HF I am running a G5RVjr camoflaged in the trees behind my house with the coax snaking through the lawn to my shack. The ladder line part runs up alongside a tree's trunk, held in place with black rope that I wrap around the tree in a spiral fashion. The dipole legs run to other trees and are also held with black rope to screw eyes in the tree's bases.
