As stated above, cabling introduces losses into the system, negating some of the gain an antenna introduces and reducing range of the RF coverage.
Attached to all antennas (except the standard dipoles), this cable provides a 50 ohm impedance to the radio and antenna, with a flexible connection between the two items. It has a high loss factor and should not be used except for very short connections (usually less than 10feet). Typical length on all antennas is 36 in. (or 12 in. on some outdoor antennas).
Cisco offers two styles of cables for use with the 2.4-GHz and 5-GHz product lines. These cables provide a much lower loss factor than standard interconnect cable, and they can be used when the antenna must be placed at any distance from the radio device. While these are low-loss cables, they should still be kept to a minimum length.
There are two types of cable supplied by Cisco for mounting the antenna away from the radio unit. The 100- and 150-foot cables are LMR600 type cable, while the 20- and 50-foot cables are LMR400 type cables. All four lengths are supplied with one RP-TNC plug and one RP-TNC jack connector attached. This allows for connection to the radio unit and to the interconnect cable supplied on the antennas.
