Thanks in advance for any help!

I have only heard of these being referred to as snake oil, meaning they are no good and don't work.

I use this type in our rural area and get nearly double the range when the antenna is mounted on a pick-up truck roof.
There are many places to buy these and if you look at your cell phone you may have a jack available under one of those rubber plugs to plug it in to.
I have gone through a few cell phones in the last few years and made sure the phone I get has the external antenna connection.
My current phone has it on the side and my previous one needed the battery cover removed to access it.

I'm wondering what kind of cross-talk issues the wireless repeater has, and how it adapts to the different systems and frequencies. How does it know that it's supposed to increase the signal strength of your phone, and not the phone in the car in the next lane?
There's a lot to be said for wires. I've always looked at wireless products as a trade-off of convenience over reliability. Cell phone dropout is bad enough without throwing yet another wireless device into the mix.
Besides, how good can it be for $23? And if it's really repeating an RF signal 24/7, it has to consume batteries like a thief.

Rick,
I have seen one of these things up close and there are no batteries, it is not a powered device.
They receive a signal on the inside pick-up and magically transmit to the antenna glued on the other side of the vehicle's window.
It's really only there for looks.
The one below is a powered relay and is similar to one that is available in our area except the receiver on ours can be several feet away from the cell phone.
One like this will boost transmitting power but I am unsure how well the phone will receive a weak signal.
