Cell phone boosters that I know about are all hype.

A cell phone is a low power radio, basically similar to one of the walkie
talkies that kids played with. Due to the limited power on Tx, I am amazed
they work as well as they do.

Still, they only work when you are more or less in line of sight of one of
the cell Tower antenna systems. Surrounded by hills, valleys, or tall
buildings, you are usually going to get poor reception.

The so called boosters tend to be flashy metal plates and such which claim
to focus the radio waves to get more range. Problem is even if they DID
focus the radio signals, which they don't, it would be a directional signal
and if you moved the phone away from the exact location, it would lose the
signal....

Are you saying these things are just basically passive horns like you
see used in microwave? "Booster" implies something a little more
*active*!
