Slow 4G connection only, but only sometimes -- SOLVED

Actually we have a covered screened porch on the Southside I could put the antenna on the side of the house on the South Side while standing on the roof of that porch. I had been thinking of that after discussing it with my wife. But I was wondering if I would be better off with the yagi versus the panel. Since I now know that I'm getting everything from one particular point.

I certainly hear you on the lightning arrestor. I actually have two 12 ft copper ground wires on a 12ft to part on the south side of the house grounding the house wiring. Because I found out that crazy builders had not even grounded the interior grounds. I also use a one shot lightning arrester on my ham antenna.  And PHYSICALLY unscrew the coax cable outside when not using it.  We have a LOT of lightning here in Atlanta.
