In order for the repeater to work well, it must be able to receive a good signal. It can then amplify the signal and re-transmit it indoors. The best way to check if there is enough signal available is to use the signal strength indicator on your phone. Go outside and hold the phone in the location you would like to install the outdoor antenna. Check how many signal bars you have. You should really see a minimum of 3-5 bars to be certain the repeater will work well for you.
If you do not see enough signal bars in the first location , try another location. Generally you will get more bars if you try a high location, such as the roof top.
The outdoor antenna that comes with the repeater kit is a much more powerful antenna then the one in your phone. If you have 3-5 signal bars on your phone outside, then the outdoor antenna will receive an excellent signal. The repeater will amplify this and re-transmit a clean strong signal indoors.
If you can’t find a location where your phone sees 3-5 bars, but instead sees only 1 bar, the repeater will still work. However, in this case, you must use a more powerful external parabolic antenna and a lower loss cable (LMR400). We can customize this for you. Just email us.
NOTE: If you can’t see even 1 bar, it is probably best not to buy a repeater.
