Is the antenna mounted properly?
Using long antenna cables or having the antenna right next to metal can reduce performance. Antenna cables
add loss to a system. Using a shorter antenna cable can help keep the losses to a minimum. Often, a longer
serial data cable can be used in conjunction with a shorter coaxial cable to keep antennas in a desired location.
The radiating portion of the antenna should not touch other metal objects or be mounted right next to them.
This can cause the antenna to operate inefficiently. It is best to allow at least several inches of separation
between the antenna and other metal structures or objects.
