4NexTek 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. For more information or a datasheet with product

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 tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
