Polyphaser RF Surge Protectors

Polyphaser lightning arrestors and RF surge protectors are designed to protect radio frequency (RF) systems from lightning strikes, power surges, electromagnetic pulse (EMP), and high-altitude EMP (HEMP) events. These devices allow desired RF signals to pass through coaxial cables while suppressing damaging DC surge energy, helping protect radios, antennas, transmitters, and other critical RF equipment.

Polyphaser RF surge protection models support a wide operating range, typically from 100 MHz to 5 GHz, and are available for power levels ranging from low-power signal applications to high-power transmitters up to several kilowatts. Their designs are engineered to remain continuously active, providing constant protection without relying on delayed activation thresholds. This makes them well suited for mission-critical communication systems used in telecommunications, public safety, broadcast, military, and industrial wireless networks.

Polyphaser surge protectors utilize advanced filtering technology featuring patented spiral inductors designed to handle the extreme currents associated with lightning events. Unlike basic inductor-to-ground designs, Polyphaser’s engineered inductors provide higher surge ratings and improved energy dissipation. Select product families, such as the GX Series, incorporate hybrid protection circuits that combine fast diode response with the high current-handling capabilities of metal oxide varistors and gas discharge tubes. This layered approach results in low voltage and energy let-through, helping preserve sensitive RF equipment and maintain system reliability.

FAQs

Q: What are Polyphaser lightning arrestors used for?
Polyphaser lightning arrestors are used to protect RF and radio systems from lightning strikes, power surges, EMP, and HEMP events by safely diverting excess energy to ground.

Q: Do Polyphaser RF surge protectors affect signal quality?
No. Polyphaser surge protectors are designed to allow the intended RF frequency to pass with minimal insertion loss while suppressing unwanted DC and surge energy.

Q: What frequency ranges do Polyphaser RF surge protectors support?
Many Polyphaser models support frequencies from approximately 100 MHz up to 5 GHz, covering a wide range of radio, cellular, and wireless communication applications.

Q: How do Polyphaser surge protectors differ from basic gas discharge tube arrestors?
Polyphaser devices use advanced spiral inductors and hybrid protection circuits that respond faster and handle higher surge currents than standalone gas discharge tube designs, resulting in lower voltage let-through.

Q: How important is grounding when installing RF surge protection?
Proper grounding is critical. Lightning energy must be directed to ground as quickly as possible. Surge protection devices should be bonded to an effective grounding system to ensure maximum protection of connected equipment.
