Long Antenna Cables
The standard length of the antenna cable is 30 meters and the
attenuation of the standard cable type (RG-213/U) is 14 dB/100 m at
400 MHz.
Other cable types and lengths are possible, but for full system
performance the attenuation of the antenna cable should be less than
10 dB. With different cable types this leads to the following
approximate maximum cable lengths:
