Post navigation My SETI Horn of Plenty uses a WR-650 rectangular waveguide. What difference would it make to taper the waveguide down to a point rather than flat back to the waveguide? I have a TV1 miniCASTER vehicle-mounted satellite uplink positioner system. It is designed to go on top of a minivan, has azimuth bearing around 50cm in diameter, and an altitude motor which attaches to an arm which holds the dish and can fold down automatically for storage when not in use. Would this suit my intended purpose to use it to point at and track masers?
