Who I have the same questioned this topic

I live in zipcode 97131  (Oregon coast).    I guess, looking at the coverage map,  that there are Verizon towers some way to the north and south of me,  but nothing very close.

If I am outside I get a somewhat reliable LTE connection.  Inside, near a window,  I have a 50/50 chance of a connection,   and away from a window I get no LTE connection.

Is a signal booster likely to work in this situation,   if so which one is recommended?   If it matters,   my devices are a Nexus 6, and a Galaxy S5.

I am asking about the "antenna on the outside of the house" variety,    not a network extender which uses a broadband connection  (I have no broadband internet connection).

Thanks for any advice ...
