Worth noting that to the best of my knowledge, Elva-1 is the only one selling a 90cm 71-86 GHz band dish.
For two reasons. Incredibly hard to aim, and the narrow beam width can actually be a bad thing compared to 60cm. With a 90cm dish on a tall steel tower in direct sunlight (steel expansion/contraction on a hollow monopole in 42C weather, for instance), or on top of a very tall (800'+) office building that sways slightly, the beam width is so narrow that it will come off alignment and vary in RSL during the day. MTI and Radiowaves prototyped 90cm e-band dishes 5+ years ago and decided not to make or sell them.
