I have gone through an involuntary cell phone service provider change. The new service is GSM and I now have no signal in the building at work (Metal building).  My dad also has poor signal at home. (metal roof)  Any suggestions for a reasonable booster or perhaps a DIY.   Thanks Jay

Wilson Electronics makes one of the better ones.

Option 1

Option 2

Option 2 is more expensive because it provides an outside, high-gain antenna. Depending on the area
it may be the better choice.

I used to have a zboost - don't remember the model but like the one linked above.  Ran an antenna outside via coax and had a unit inside.  When it was off I had no bars, when it was on I had like three.  You just have to put the antenna somewhere that gets signal.

I ran into similar problem when I moved from Arizona to South Carolina. Verizon worked well in Arizona but they have terrible coverage in the Charlotte/ Rock Hill area. I had no signal in my house and very low signal at work. I bought a directional antenna with 50 ft of low loss cable but never installed it. I switched to ATT instead and the problem was solved. ATT has great coverage in this area.  I'll sell the antenna for half price of a new one if you want it. You'll need a cable adapter for your phone. The adapter it came with was for older Motorola phones.

1. Initial glance I thought this was a Hunger Games thread
2. Caution OP, almost this very same question got me mixed up with this bunch (of course we've already corrupted you!)
