Page 11: Suggested Cable
Replace the ceiling tiles. Step 15 Suggested Cable Cisco recommends a high-quality, low-loss cable for use with the antenna. Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss). -
