I’m looking forward to the kit as well.
The ‘sorcery’ scared me too at first. The LNB probably has about 6-8dB antenna gain all by itself. This is in the same ballpark as the passive L-band patch antenna for DC 2.0.
As long as there is enough signal to noise to decode the signal is all that’s really required. My concern at first was the effective beamwidth of the antenna is not narrow enough to eliminate signals from other satellites a few degrees on either side of the satellite that is broadcasting. But if the other satellites are not broadcasting SCPC signals on the same frequency, this is probably not a problem. Hopefully there’s enough scrambling and FEC to effectively deal with interfering signals.
Galaxy 28 is already Southwest and fairly low to the ground here in Seattle, Washington, United States: 138.3° & 26.5°. I have mountain ridges that run east-west just to the south of me. The satellite barely scrapes over the top of them. A small dish may be required up in Alaska or northern Canada. I’m not concerned.
