Installation and Working:
The installation procedure may vary according to the product.
Identify the most suitable location with the strongest signals, to install the external antenna. You can do this by looking at the signal strength indicator on your mobile phone handset.
Use the mounting brackets and to vertically install the antenna, at least three feet away from metallic objects like air conditioning units and pipes.
Take the coaxial cable and attach it to the base of the signal antenna.
By using an optional window entry kit, you can run the other end of the coaxial cable through your window and attach it to the base unit which is kept indoors.
Ensure that the base's antenna is at a 90 degree angle to the base unit.
Connect the power supply to the base unit. You will need to adjust the distance between the two antennas to eliminate any error indications
