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.

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. -- Regards, Noel Butler This Email, including attachments, may contain legally privileged information, therefore at all times remains confidential and subject to copyright protected under international law.
