I had the oportunity to use one of the Pro Portable flyaway terminals on my recent vacation. ViaSat sells these to outfits like the Red Cross, news agencies, and other outfits needing a compact package that can be checked on any commercial airliner or tossed in the back of a mini-van, etc.
While the Pro Portable antenna is designed to be quickly assembled and pointed by the user, there is also another antenna being sold now for satellite news gathering (SNG). The SNG antenna is self pointing and works while parked just like any of the other non-tracking receive only antennas commonly used on RVs today.
The Pro Portable terminal worked very well for me. I logged just under 4,000 miles in a month of traveling around the western US. Along the west coast service was via ViaSat-1, further east at Yellowstone service was via WB-1.
Download and upload speeds were better than the 4G wireless card I had with me (which connected at 3G most of the time, and sometimes not at all) and were typically in the 12/3 Mbit/s range on ViaSat-1.
I was able to use the terminal to attend a WebEx meeting as well as all the standard emailing and web browsing one would expect. Worked quite well for Skype too. Pretty much felt just like I was in my office most of the time. Great for watching Netflix movies as well.
In my opinion, if you own a several hundred thousand dollar diesel pusher motorhome, the prices of these antennas are not out of range.
Given the poor quality of many of the WiFi networks at the RV parks we visited, and the poor wireless coverage in some of the out of the way spots, the satellite solution is a great thing to have.
Sadly, I had to turn the antenna back in once I finished my trip. I'm really going to miss it on my next trip . . .
So, bottom line, there is a solution that will work for RVs, but right now the focus is on SNG, and the consumer RV market is not yet being developed. I expect that to change at some point once the SNG market is taken care of.
