This RG213 coaxial cable features a bare copper inner conductor and bare copper braid shielding, so the quality of this RG213 coaxial cable is superior to LMR400 coaxial cable. Bare copper braid shielding for enhanced isolation and EMI resistance. The rugged RG213 coax is built for high-power handling and low-loss operation. If power handling, signal strength, and propagation are your concerns, this RG213 coax cable more than meets all your requirements. This low-attenuation RG213 coaxial cable delivers low loss: the loss of this 100FT RG213 coaxial cable at 100MHZ signal frequency is about 2.2 dB and the SWR 1.20. This RG213 coaxial cable is best suited for high-power long-run antenna installations in high-frequency applications such as Broadcast, Ham Radio, CB Radio, Wi-Fi, GSM, Base Station and Mobile Uplink. Uniformly coiled and bound with quality cable ties. Please note the wood spool is not included
