NexTek, Inc. has announced a gas tube lightning arrestor family that is designed to maximize protection and expedite installation. Model PTR0NF7AF units protect the coaxial line from transients, and they also provide a compact way to transition from semi-rigid or corrugated cables to flexible or braided jumpers. The SurgeGuard lightning arrestor transitions from 7-16 to the more compact N-type connector. A 7-16 DIN female is provided for connection to the larger coaxial cable, and an N female is available for connection of the internal jumper. The operating frequency of the PTR series is optimized to 2.2 GHz, and it provides DC pass capability with a typical IM3 rating of -120 dBc.
