I've seen a few sites selling external antennas for the Charge. I live out in the vast wilderness of East Bumblecrapfail, NC, and only have, at best, one bar of 3g signal at my house. I am beyond the reach of cable or DSL. I need something better than this HughesNet abomination that I mockingly call a net connection. Halp! Are these things safe? Will they do anything to boost my signal? Anyone have any experience with them? HELP A NERD OUT, I JUST WANT INTERTUBES AT HOME. Thanks in advance.
