Internal atenna boosters are thin metal strips that fits between the battery 
and the cellular phone and claims to increase reception performance for analog 
as well as digital cellular phones.  It also claim to be equivilent to having a 
4 foot antenna in a metal strip that is 2 inches long.  How does it work and 
does it help for digital phones a lot?
