Calculations for WR-650 waveguides for hydrogen line radio astronomy

December 7, 2025 Admin

When I search for WR650 waveguides, I get results for 12-26GHz rather than correct wavelengths that cover 1.4GHz. Why is that?
Can I use a square coaxial to waveguide adapter to act as waveguide on my 1.5m dish for hydrogen line?
