I don't recall seeing a requirement for a licensed installer in Part 25 but I will check again because I'm curious and really should know anyway. $2K/mo. is a decent price for CONUS coverage, there is still allot of demand. You can often find deals on used
BUCs and LNBs on EBay. I recently bought NJRC 4W BUC for $125 and it even worked. Each earth station would need its own FCC license which is a pain to file for and if I remember correctly has a filing fee around $400. You need a minimum antenna size of 1.2M
to be "routinely" licensed. There are satellites every 2 degrees in the CONUS arc. Every time you move the antenna you need to contact the satellite operator to verify correct pointing and polarization adjustment and confirm you are not exceeding your contracted
downlink EIRP. The only way this would make any sense would be if a group got an STA and got certified by the GVF.

This would not be in the amateur satellite service, so we'd need to use<br>
commercial type-approved ground equipment, or gain type approval for our<br>
own designs. That could get very expensive. Check out, e.g., Qualcomm's<br>
filings for its Omitracs service for what was required to get something<br>
novel past the FCC. The chief concern with commercial geostationary<br>
satellites is spraying adjacent satellites with uplink QRM. They're<br>
packed quite closely in longitude these days, close enough that the<br>
usual ground antenna patterns can't be assumed to roll off fast enough.<br>
So you have to analyze the system and show it's not objectionable. Also,<br>
assuming the satellite in question is also carrying other traffic, you<br>
have to show that your uplink transmitters are clean enough to not<br>
interfere with those signals.<br>
<br>
On the other hand we would not be subject to limitations on 3rd party<br>
traffic or encryption.<br>
<br>
I seem to recall that ground stations for retail Internet access have to<br>
be installed by professional installers, which could also get expensive.<br>
I don't know if that's a FCC requirement, or just a vendor policy.<br>
<br>
This is not an easy or cheap option. $2000/mo for the transponder would<br>
just be the beginning. It's not like QO-100, where the satellite<br>
transponder itself operates in the amateur satellite service (2.4 GHz<br>
up, 10 GHz down).<br>
