The SX™ radio frequency DC-blocked filter protectors are ideal for RF coaxial applications where DC is not required. The SX™ can be used on high-powered RF feeder lines in the range of 350 to 2,300 MHz, as well as, low-powered microwave sites at 2 to 10GHz. The SX™ is available in a multitude of connector configurations each exhibiting low return loss, insertion loss and let through voltage. The SX™ is a patented DC blocked filter design that maintains the lowest surge let-through of any protector in our industry. The SX™ outperforms all of the competition in terms of surge capacity, RF performance, durability, and reliability in the field. It is no wonder that the SX™ has quickly become the standard to which all other lightning protection is compared.
