LP-350A – Arc-Gas Lightning Transient Voltage Surge Protector

Overview Other Details Reviews Similar Products –> Product Description LP-350A Arc-Gas Lightning Transient Voltage Surge Protector Protect your valuable radio equipment from damaging static buildup and lightning-induced voltage surges. The LP-350A Arc-Gas Lightning Transient Voltage Surge Protector is a compact inline coaxial lightning arrestor designed to help protect sensitive radio equipment connected to outdoor antennas. Using Gas Discharge Tube (GDT) technology, the LP-350A provides a low-loss path for normal RF signals while diverting excessive transient voltage to ground when the protection threshold is exceeded. With dual UHF female (SO-239) connectors, the LP-350A installs easily between the antenna feed line and radio equipment using standard PL-259 terminated coaxial cables. A dedicated grounding terminal provides a convenient connection to a properly installed station or earth ground. Key Features Arc-Gas / GDT surge protection technology Protects against static buildup and transient voltage surges DC500 MHz operating frequency range 50 Ohm impedance Less than 0.1 dB insertion loss 350 VDC nominal discharge/breakdown voltage Handles approximately 300350 Watts PEP, depending on operating conditions/variant Dual UHF female (SO-239) connectors Compatible with standard PL-259 coaxial connections Dedicated grounding terminal Compact inline design Field-replaceable gas discharge cartridge Suitable for amateur, CB, GMRS, and commercial two-way radio installations Technical Specifications Product Type Coaxial Lightning Surge Protector Protection Technology Gas Discharge Tube (GDT) / Arc-Gas Frequency Range DC500 MHz Impedance 50 Ohms Maximum Power 300350 W PEP* Insertion Loss < 0.1 dB Discharge Voltage 350 VDC RF Connectors 2 UHF Female (SO-239) Cable Connection PL-259 Male Ground Connection Dedicated Ground Terminal GDT Cartridge Field Replaceable Dimensions Approx. 66.5 40 20 mm Configuration Inline *Power rating can vary by source, operating frequency, and specific LP-350A variant. How It Works During normal operation, the LP-350A allows the RF signal to pass through with minimal insertion loss. If an excessive transient voltage reaches the coaxial line, the gas discharge tube conducts and provides a path toward the grounding terminal, helping divert the surge away from the connected radio equipment. This makes the LP-350A particularly useful for installations where antennas and coaxial feed lines are exposed to outdoor electrical activity. Typical Applications Two-Way Radio Communications HF, VHF, and UHF base stations Outdoor antenna systems Fixed-station transceivers Home base stations Vehicle and RV installations External antenna systems Dispatch stations Security communications Fixed radio installations Static Protection Helps dissipate accumulated static charge on outdoor antenna systems Provides protection against transient electrical events associated with nearby lightning activity Installation Note For effective surge protection, the LP-350A's grounding terminal should be connected using a short, low-impedance grounding conductor to a properly engineered station/earth ground system. A coaxial surge protector should be considered part of a complete grounding and lightning-protection systemnot a guarantee against a direct lightning strike.

This is the third one I have bought. The two others are giving great protection on other antennas I have built. Low-loss too.
