Radio observation in hydrogen line (1420MHz)
Waveguides
In LRO-H2, I use a cantenna as my waveguide, and aim this at the dish, rather than out into space. Does the presence of the dish change the ideal dimensions for the cantenna and position and length of the monopole inside it?
Short answer: No—the dish doesn’t change the waveguide dimensions of the cantenna.The can’s internal diameter and the probe/back-short geometry are set by your operating frequency and waveguide mode, not by…
