BG7MGW One of the key characteristics of UV line-of-sight is that the link budget is very generous when there are no obstructions, and whether or not it can be successfully established largely depends on the visibility conditions. Therefore, even a small difference in gain has little impact.
Similarly, in the UV band, transmitting to satellites and meteor debris requires specific power and gain levels. However, when using EME (Earth-to-Moon), every 1 dB change directly affects the success rate and signal quality reports.
