I'm reading this thinking.... "Push is going to take a long long time to ever really understand how things work because Push thinks he knows a whole lot more than he really does, so everything anyone says to try to explain things turns into a big old long argument." You are pretty much wrong about the path. It is possible near the MUF or under some very special conditions to have a difference with direction, but is the exception by far rather than the norm. Several others gave you excellent advice about that that you simply chose to ignore. It is possible to build a one-way mirror, it just isn't the norm. You are absolutely wrong about antenna tilt. The G3 gave excellent advice that you choose to dismiss. If you built a big enough antenna far enough from earth so the earth did not influence the angle, then what you say would be true. But at HF at any height below a several hundred feet above ground and with a practical antenna for most people to build, G3TXQ is absolutely correct. To build an antenna with wave tilt here on 40 meters, I have to have antennas at 90 feet and 180 feet and phase them. The result is about 1% of the time something elese is better than both antennas in phase. But of course you know better. You know all a person has to do is tilt the antenna. You only ask the question to waste everyone else's time, because you learned all about antennas on CB..... Or do I have that wrong?
