<div class="pre" style="margin: 0; padding: 0; font-family: monospace">If you're getting the "RV/camping/portable" equipment you'd want to use your 12volt system that nearly all campers and RV's I've seen with factory electrics come with (A couple RV models are 24v) so the DC supply woud need to accept 12 to 48 input, slightly less heat is generated if you use 24v and even less again if 48v since it only bucks it for the 12v parts of the circuitry in modem. You would not want to use an AC supply, defeats the purpose of the design of that service, the 12 to 48v boost converters for the dish to work have decent heat sinks, a little better ventilation in the modems for that little bit of extra heat would be beneficial.</div>

They could reduce that in-car power need by bringing the sats even lower, or other non-sat objects like HAPs. Or by augmenting the starlink sat antennas sizes.</div>

<div>They are identical hardware, no extra power is needed, since there is 350 odd km's to the satellite, do you really think the 2 or so metres AGL for campers, would really need more power compared to the standard unit at 10 metres AGL, at say a house mounted dish :) In early days I remember quite a few youtubers using the stand on the ground in their back yard, and they probably still do.</div>
