The Broad-Pro 50C,PL-259s,100ft has a high-resistance copper screen made by means of a 24-spool braiding machine, generating 50% more crossovers compared to traditional 16 spool machines. This braid is highly effective against low frequency impulsive noises. It also has a high pressure physical injection foam polyethylene triple layer dielectric. The inner conductor is 99.9% pure electrolytic annealed bare copper (2.76mm). The copper foil has an applied PE-coating, placed in order to prevent foil cracking due to short radius bends. The black protective PVC jacket is UV-resistant and extra-flexible.
