NexTek Expands Sales & Marketing Team

HPR Series

NexTek has seen some recent changes in personnel, made with an eye firmly toward the future... More...

The HPR Series is a rugged, high current feed-through filter that sets new performance benchmarks. Designed to operate at current levels up to 400 amperes and voltages up to 1000 VDC, the HPR Series is ideal for reducing high frequency noise on high current lines. HPR filters can be used to reduce noise emitted from the power system or to isolate noise from loads. The unique ability to remove high frequency noise from very high current lines makes our patented HPR a proven and economical solution to your high current filter application. More…

Coaxial Lightning Protection

Telecom: PGT 7F Series

Finally a No Maintenance / High Surge / DC Pass Coaxial Lightning Protector for Telco

Designed for GSM, CDMA, UMTS, AMPS, PCS, & GPS applications

TTA (Tower Top Amplifier) Lightning Protection

Eliminates Maintenance and Passes DC Current

80kA Transient Surge Protection

Designed for Telecom applications with 7/16DIN connectors, this new surge arrestor provides excellent RF performance specifications and represents a significant advance in power surge technology. As a result of patent pending design improvements, this device exhibits over fifty times the industry-standard life expectancy when exposed to a transient current of 30kA yet requires no gas-tube maintenance.

The maintenance free PGT 7F series is rugged and waterproof. It is designed to operate at frequencies ranging from 0.82-2.2GHz. It is characterized by bi-directional protection, low VSWR 1.05:1 (typical) and Insertion Loss 0.05dB, high RF power, low PIM, and dc pass capability.

The SurgeGuard™ PGT 7F series of coax lightning arrestors is available in various polarity configurations.

Coaxial Lightning Protection

QSS & QWS Series Quarter Wave Stub

From 380MHz to 6GHz
Up to 100kA surge protection
Large selection of connector configurations
Bidirectional protection
Rugged and waterproof

The next generation SurgeGuard™ quarter wave stub series lightning arrestors are available in assorted connectors and genders. Individual models are available in various frequency configurations including the wideband 0.82 - 2.2GHz and 2.4 - 6GHz units. Multiple narrowband devices are also available ranging from the ultra-compact and industry unique 380MHz unit to higher frequency units exceeding 6GHz. As an option, many models are also available in reverse polarity.

The quarter wave stub devices feature best-in-class performance specifications, including bi-directional protection, low VSWR (1.05 typical), normal and reverse polarity, high RF power and ultra-low let-through (5V typical). Using robust materials in construction the maintenance free quarter wave series is ruggedized, weatherproof to IP68 standards, and can withstand multiple strikes as well as very high transients up to 100kA
