S3 antenna signal amplification

aloha

i live in a Verizon cell tower shadow area on biggie island.  a wall plug network extender is required to make and receive voice calls.  however, the electric power goes out here regularly. 

is there any way to passively augment the signal strength received by my Galaxy S3 smarty phone during these numerous power outages? 

FYI:  sending and receiving email is still possible with no network extender.

cheers
