homemade signal booster?
to use a UHF amplifier, to pick up the towers signal and rebroadcast it. of coarse since things like WiFi, Bluetooth, and cellular 2G/3G/4G networks use two way radio, the signal can go back to the reviving end of the UHF amp, and get broadcasting to hit whatever tower. my phone should better recognize the tower, as if i just magically made a tower 2 feet away. however this might also amplify stay noise.
if this idea doesn't work, why not? i think i am going to need at least a 20dB increase in power, but as of now i need to do more research.
but if i can buy a product that does a similar thing for less than $40, i would.
