Internet booster?

We need an internet booster to improve the performance of our Verizon connection. Suggestions? Where to purchase?

One of the issues is that the old CDMA technology allowed up to ten towers to "share" the signal. GSM does not do this. But the tower networks were put in place first--so fringe areas may nearly always have poor service.

Verizon is NOT GSM

i have used a Wilson sleek for years, while not the BEST system
it is certainly the most affordable, and better than anything else that can come close in price..
and yes the truckers cellular antenna coupled to the sleek is an excellent idea
