Umm...About that 12' reception issue above...I was totally wrong. I wasn't reading the meter on my phone correctly.
This evening I was out in the trailer playing with the new gadget and my various devices. I found the Cellular Booster is extremely sensitive to the distance between the phone and the indoor receiver antenna as the post suggested above.
Some tests I performed.
With the phone right up against the antenna I saw signal strength of -88 (lower the number the better)
One foot away from the antenna.... -92
Two feet away from the antenna.... -100
Four feet away from the antenna... -103
Six feet or more away from the antenna... -109
Cellular Booster turned off ... -111
This is a huge difference. These numbers are logarithmic. I haven't done the math but the difference between -88dB and -111dB is many hundreds improvement.
So, if you can't sit extremely close to the antenna, or actually tie it to the phone with a rubber band, you will not experience the best performance. If you are using your phone as a HotSpot or are actually using a HotSpot, I'd place it right on top of the antenna and use WiFi to connect to the phone or HotSpot. If you are using the phone to talk, I'd ties the phone to the antenna and then use a wired or BlueTooth headset to communicate.
Obviously, this limited range precludes anyone from using your cell booster unauthorized.
Hope this helps!
