Its most important advantages are dimensions compliance with RG-174. The RF-100LL cable can also be used in professional antenna systems as a cable connecting low-power devices or the cable from which the connector is made, e.g. in devices operating in the 6GHz band. The cable is equivalent to RG-174 / U. The RF-100LL cable is a variation of the RF-100 cable with a slightly larger diameter of the middle vein and a foamed polytetylene dielectric. These two features allowed attaining slightly less attenuation than the standard RF-100 cable. RF cables are a group of Belden cables designed for use in WLAN, WLL, UNII, ISM, LMDS, MMDS, NMT, GSM and 3G devices.
