PTR7AF7AFxxK arrestors measure 119 millimeters by 45 millimeters, have 7/16 DIN female to 7/16 DIN female connectors, and can deliver a maximum of 50 kilowatts of RF power at a maximum through-current of 25 amperes. The K1 series products can use a range of 1.4-kilovolt to 3.5-kilovolt gas-discharge tubes and have a nominal impedance of 50 ohms. Additional specifications include a low return loss of 1.20 to 1.30 maximum and an insertion loss of only 0.10 dB to 0.20 dB. All SurgeGuard products are considered military grade and are designed to be both waterproof and dustproof (IP68 Standard). This series provides multiple-strike protection and up to 40 kiloamperes-plus (8 x 20μs waveform) of surge capability for a single event. www.nexteklightning.com
