Design of offset satellite dish – is it half a parabola?

Admin August 28, 2025 No Comments

An offset satellite dish is not literally “half a parabola,” though it is related to a parabola. Here’s the distinction: So, instead of being “half a parabola,” an offset dish…

LRO-H2 Radio Telescope (150cm Solar Cooker Dish) Radio observation in hydrogen line (1420MHz)

Is it worth adding a second probe at 90 degrees to my cantenna waveguide on LRO-H2, my Solar Cooker Parabolic 150cm Radio Telescope?

Admin August 28, 2025 No Comments

Great question — this gets into radiometer theory and feed design. If you add a second probe into your WR-650 feed at 1420 MHz, what happens depends on how you…
