Selecting antenna cables
Antenna cables are needed for feeding the signal of a remote anten-
na to the receiver. However, all antenna cables attenuate the anten-
na signal (cable attenuation). Since different types of cables have
different attenuation values, each type will perform best at a dif-
ferent length. While low-attenuation cables are usually thicker and
more expensive, they can be used for much longer runs. You can
compensate for long cable runs by using antenna boosters or active
antennas. In some cases, however, using the next higher (if slight-
ly more expensive) grade of cable may do the trick, eliminating the
need to use active antenna components. The right type of cable can
be essential to the performance of your wireless system, prevent
problems, and help reduce costs.
A bank of dip switches on the boosters and the PS 4000 antenna
splitter allows you to match the RF signal level to the antenna input
depending on the frequency band, antenna type, cable type, and
cable length.
