Short answer: Yes — but with caveats. A square/coax-to-waveguide adapter can act as a waveguide feed/aperture for a 1.5 m dish at the hydrogen

It happens because “WR-650” means two completely different things depending on context, and most search engines don’t know which one

If you want a rectangular waveguide that works well around 1.4 GHz, a common standard choice is WR650. ✅ Why WR650 at ~1.4 GHz

Here’s a ready-to-use block diagram plus a practical minimal parts list and quick build/test checklist so you can turn your

Good questions. First, to be clear — by “convert … to a full waveguide” I assume you mean: you have

Short answer up front: a 2.4 GHz LHCP helical dish feed is a perfectly sensible and widely-used solution for uplinking

Nooelec’s documentation lists the SAWbird+ H1 (no 50 Ω “reference” termination present) at ≈0.8 dB NF and the versions that include the
