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. For more information or a
