Andrew, if you Really want to do this you need to be Meticulous in Matching and Verifying Each feed system. It takes time & effort. 1) You MUST use software…

At last! Go this 2nd monopole installed on the cantenna at 90 degrees to first – so now I can collect vertically and horizontally polarised 1420 MHz data – given…

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…
