Faceplate-Mounted and Ceiling-Mounted Antennas and Cabling

Depending on the wireless environment, wall-mounted or ceiling-mounted antennas may be preferred

for optimum radio coverage. If the length of the coaxial antenna cable is insufficient to cover the distance

between the 3G wireless HWIC and the location of the installed antenna, you can use ultra-low-loss TNC

extension cables between the 3G wireless HWIC and the antenna cable.

RF energy is carried between the antennas and the radio equipment through a coaxial cable. An antenna

cable introduces signal loss in the antenna system for both the transmitter and the receiver. Although the

cable run can be 100 feet (30 m) or more from the 3G wireless HWIC to antenna locations, the longer

the cable run, the greater the signal loss. To reduce signal loss, minimize the cable length and use only

ultra-low-loss antenna cables to connect radio devices to antennas.

To connect faceplate-mounted or ceiling-mounted antennas, follow the installation instructions for your

antenna:
