Use in Harsh Environments MOOKEERF cable jackets are made of high quality PVC and can be used in harsh environmental conditions without affecting the performance of the cable. Superiorly Constructed Connector The outer shell of the KMR400 cable's connector is made of Copper Nickel Plated, which is corrosion-resistant and resistant to oxidation, and the inner needle is Brass Gold Plated, which ensures good signal transmission. Heavy Duty Low Loss Cables High density tinned copper braided are designed to maintain 95% shield performance. It would made this UHF jumper cable is really low loss and maximum protect the signal during the transmission.
