RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

NexTek Lightning Protectors Easily Transition from Rigid
to Flexible Coaxial Cable

Westford, MA, January 30, 2007 -- NexTek, Inc., a leading designer of best-in-class SurgeGuard™ lightning protection and EMC / power conditioning products and services, announces a gas tube lightning arrestor family designed to maximize protection and expedite installation. Most cable tower installations use large, rigid or semi-rigid coaxial cable down-lead from the tower. Frequently a transition from the tower to the cabinet uses a more flexible and smaller cable. NexTek PTR0NF7AF protectors not only protect the coaxial line from transients, but also provide a convenient and compact way to transition from semi-rigid or corrugated cables to flexible or braided jumpers. The SurgeGuard™ PTR0NF7AF family is a gas tube lightning arrestor that transitions from rugged 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 for high performance to 2.2 GHz.

The PTR0NF07F exhibits additional industry-leading performance, including 10x multiple strike capability @ 20 kA, and one-time 50 kA (8 x 20 μs) surge capability, bi-directional protection and an operating temperature range of -40°C to +90°C. The PTR series provides DC pass capability with a typical IM3 rating of -120 dBc.

Able to withstand harsh environmental conditions with an industry leading IP68 rating, the high reliability PTR series is both rugged and water proof, featuring gold plated contacts for long life applications. The N connector bulkhead threads can be used to attach a grounding wire, through a bulkhead, or to a mounting bracket. Replaceable heavy duty protector capsules are available in voltages of 90 V to 1000 V, as required for RF power. The SurgeGuard™ PTR series is value-priced at $39.00 each in OEM quantities.
