There is an entire unused coax network in the house from the headend to various locations. House has a Crestron DM system so the coax was run "just because".
Roof has one remaining RG6 and one Cat 6. The others at the roof are taken up by a Directv dish, XM antenna and an AM/FM antenna.

I was always under the impression that Wilson stuff used RG11 and that RG6 was a total "no go" for their stuff. Their 4G repeater has been "coming soon" on their website for quite some time too. If I were to be able to do anything, it would be that. I will call them in the morning and see what (if anything) they have that might work.

The M-Cells and Verizon cellular to IP based "hot spot" things won't work because there is no way one of them is getting a GPS lock in "the cave", nor do they hand off. And to top it all off, the client lives out of the USA primarily, so I doubt I will find one that works with a Canadian cell provider.
