Just got a Winegard Pathway X2 and a Wally. There were a lot of threads in the tech section here about this and the Pathway came out as most recommended. There was some buzz about the RF Mogul, but at $2000, it had better make up programming if it can't get a signal.
FMCA has a Verizon Wireless deal. Hotspot for a penny and unlimited data for $50 a month. They throttle above 25 gig, but people who have this say they really don't notice the difference.
Do not try to sign up for the VZW deal on you existing account. Use another email when you sign up for the FMCA deal. That's 6 hours of my life I'll never get back.
