Between the ice and wind at some qths like mine, laying cable in loops on a top plate is just begging to have it catch on a corner or be frozen in place and tear. It is usually a bad idea for anyone

Simply put, antennas at a given height have MULTIPLE lobes at different wave angles of varying gain over flat ground over average soil. If you have anything other than flat ground and especially if y

Your assertion that The one lobe per half wave in height is accurate unless one is on the side of a cliff or very substantial downslope is far too simplistic and not accurate. I have neither situatio
