Cisco кабель low-loss 6m + RP-TNC connector
The antennas in a беспроводной network installation чёрный be close to the users. The location of the antennas are not necessarily required to be close to the connected switch or to a computer room. The кабель run can be 100 feet or more from the AP or bridge to antenna locations. RF energy is carried between the antennas and the radio equipment through a coaxial кабель. An antenna кабель introduces signal loss in the antenna system for both the transmitter and receiver. To reduce signal loss, minimize the кабель length and use only low-loss or ultra low-loss antenna кабель to connect radio devices to antennas. RF coaxial кабель = loss of signal strength Loss of signal strength is directly proportionate to the length of the кабель segment. As the diameter of the кабель increases, signal loss is decreased, but at much higher purchase cost. As signal frequency increases (higher numbered channel) loss increases. Low-loss кабель extends the length between any Cisco Aironet product and its antenna. With a loss of 6.7 dB per 100 feet (30m) for low-loss кабель and 4.4 dB for the ultra low-loss кабель, these cables provide installation flexibility without a significant sacrifice in range or performance.
