Maybe he's trying to block out a multipath reflected or ducted signal. I think this is difficult or impossible because1) the angular difference is too small2) the shield is too close to the antenna3) knife edge diffraction---- Original Message ----From: "Cameron Crum" Sent: 8/14/2024 9:33:48 AMTo: "AnimalFarm Microwave Users Group" Subject: Re: [AFMUG] parabolic shield calculatorNothing I know of, but if they are not arriving parallel to the axis, they will not pass through the?focal point (which is where the feed is). Remember?tha angle of incidence = angle of reflection, so for any given point, if you know the angle which it arrived in reference to the point at which it hits the parabola, it will reflect at the same angle when it leaves. What is the point of the exercise? Parabolic dishes have a pretty specific use, and it isn't in serving things outside of the primary axis.?On Tue, Aug 13, 2024 at 12:05?PM Steve Jones <thatoneguyst...@gmail.com> wrote:Nerds: Is there a visual calculator similar to?https://www.desmos.com/calculator/br9pfx6z8c that will visualize inbound paths to show where they would reflect in regard to the feedhorn?
