Overview

DX Engineering Surge Arrestors

DX Engineering Surge Arrestors offer the best protection for your RF equipment. They are multi-strike capable coaxial cable lightning protectors for use on antenna systems operating on all frequencies from 1.5 to 700 MHz. Their RoHS compliant design is available in Flange Mount with connectors parallel to the grounding panel or Bulkhead Mount with one longer connector to pass through the grounding panel. Mounting hardware is included. Each protector mounting style is available with either two Type-N female or two UHF female, SO-239 connectors. DX Engineering lightning protectors handle 2,000 watts CCS RF on HF and 50 MHz antenna feedlines under 3:1 SWR. They feature concise labeling of their power handling curve by frequency notation: 2kW at 1.5 MHz, 2kW at 50 MHz, 500W at 220 MHz, 250W at 700MHz.

DX Engineering Surge Arrestors also offer the industry standard equipment protection that broadcast and commercial communications systems have depended upon for nearly 50 years. These protectors feature a DC blocked specially configured high-speed gas tube design that passes only RF frequencies. From antenna to protected equipment ports, these protectors have no DC continuity between connector center pins, in order to provide superior response to pulse energy. The only application were these protectors cannot be used is in systems that require remote accessory DC power (bias-tee) to be applied onto the feedline. All other RF only applications are suitable, even "floating" antennas that are not DC grounded.

DX Engineering DC blocked gas-protector circuits bleed off static charge to ground without the popping noise of arc-type protectors. Any slow voltage build up from wind driven rain, snow or dust brings the protector to a threshold for soft turn-on as the gas quietly ionizes momentarily. As with other multi-strike capable protectors, higher level pulses are instantaneously and repeatedly shunted to ground. These protectors provide the 24/7 radio equipment protection required by communications systems engineers and technicians in broadcasting, commercial, military and government installations.

Amateur Radio and SWL enthusiasts also benefit from installing these affordable, commercial quality RF coaxial lightning protectors. Buy DX Engineering Surge Arrestors, with confidence, for your antenna systems.
