You get what you pay for. When I was in Afghanistan I paid $3,500 for a satellite Internet receiver. They gave me the wrong coordinates and I needed to move my setup several times before I could finally get a signal. I knew the latency would be atrocious, but the download speed was barely adequate for Tradewars 2002, and it was supposed to be fast enough for 8-10 personnel.
Towards the ends of my deployment they flew me to a base adjacent to our main base in Kandahar Airfield. They had a room of laptops hooked up to a tan mini receiver that automatically adjusted.
The lag was still bad, but it was high-speed.
It was marvelous!
Don't worry! I finally sold my equipment for $500!
