How to boost my cellular/mobile signal range?

I currently have the iPhone 5S on the Three network. I'm able to get 4G as I get it at my neighbours house across the road but can't not seem to pick it up at my house (Unless I lean out the window)

I'm not an engineer so I'm not to familiar with what's out there but on a quick google I see something called a Cellular Repeater? Or Signal Booster? Antenna's etc?

I've come across numerous boosters for Wi-Fi but can't seem to find any for 4G/LTE etc!

I need something that will just give me that extra boost so I can get the 4G!

Where I live, I can't have decent Wi-Fi (Bad wiring) so a good 3G and 4G is vital to me!

Just to clarify:

I need a signal booster or an antenna of some kind to give my iPhone 5S, on the Three network that boost to get the 4G signal.

If you can offer some actual product that would be fantastic or give me an idea of where to look!

My question is is there anyway to sink my iTunes library to my new computer including apps and music

Why is my iphone stuck on a loading screen?

Does anyone know what's wrong with my iPhone 5? I tried restoring it by going to settings & then Resetting all data & content, but it got stuck on a black loading screen, so I just held the power button in. After a few times of doing this, it wouldn't work so I tried to go on iCloud.com, then find my iphone, & then erasing my iphone from there. The same thing happened. Now, whenever I turn my iphone on, it just keeps going to the loading screen.

Added (1). No, it is not the screen that means connect to a computer. It's just a circle that goes around.
