Coaxial Lightning Protectors

PolyPhaser Coaxial Lightning Protectors

PolyPhaser Coaxial Lightning Protectors are designed for general, single-transmitter use in the 1.5 to 700 MHz frequency range. PolyPhaser protectors are available in two mounting styles: "Bulkhead Mount" protectors have a longer connector and hardware to mount it through the grounding panel. "Flange Mount" protectors anchor to a grounding panel with both connectors parallel to a flat surface. PolyPhaser Coaxial Lightning Protectors use a DC blocked specially configured gas tube design that has no DC continuity between the two center pins. PolyPhaser's multi-strike products are designed to pass RF frequencies and block all DC. These protectors appear as a DC open between surge and protected ports and offer industry-standard protection. PolyPhaser protectors are suitable for all types of antennas, even "floating" antennas that are not DC grounded. With PolyPhaser DC Blocked protectors, any slow voltage build up from wind driven rain, snow or dust, will not get to the equipment. As the protector reaches threshold for turn-on in a dc blocked circuit, it will go into a momentary soft turn-on as the gas barely ionizes and bleeds the static charge to ground. This does not create noise since it will not get to the arc mode and lasts only a short time. PolyPhaser protection devices have been chosen and specified by communications systems engineers and technicians for 24/7 service in broadcasting, commercial, military and government installations. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Trusted by Amateur Radio operators for over 40 years, PolyPhaser Coaxial Lightning Protectors are ready for your antenna system installations. They are available here, at DX Engineering.

Alpha Delta UHF Connector Coaxial Cable Surge Protectors

Alpha Delta UHF Connector Coaxial Cable Surge Protectors have SO-239 connectors and are rated for 200 or 2,000 watts at frequencies up to 500 MHz. They are not DC-blocked, so they will pass control voltages in applications requiring the coaxial cable to carry both RF and DC voltage. They may be easily mounted for the most effective grounding with a 1/4-20 bolt or stud (depending on model) in a single hole or as a bulkhead-mount through the grounding panel. In a study under the auspices of the U.S. Dept. of Energy, utilizing the satellite FORTE launched in 1997 carrying VHF lightning discharge sensors, it was determined that there can be damaging lightning energy emissions throughout the 30 through 300 MHz VHF spectrum. Before FORTE, it was thought that most lightning energy emissions were primarily in the VLF range. Therefore, the damage threat can be anywhere from VLF through VHF. Through the careful design of the Alpha Delta Arc-Plug® gas tube module and precision, constant impedance through-line allowing proper firing characteristics, these devices are designed to provide effective protection throughout this entire spectrum. Other surge protector designs may only utilize simple VLF filters with no gas tube backup. Additional features include: * Excellent broadband performance from DC through 500 MHz, compared to the narrow-band DC-blocked or stub designs. * Innovative impedance compensated through-line cavity design allows control voltages to pass through the device, instead of the "wire-around" requirement of DC-blocked designs. This design allows "in-circuit" cable sweeps. * Innovative, fast-acting gas tube replaceable Arc-Plug® module can be removed and replaced in the field in about one minute with no tools required, and without having to remove the protector from the circuit. The "O" ring sealed knurled knob does the trick! * The Arc-Plug® modules and connectors are "O" ring sealed for complete weatherproofing. * Effective performance. Due to the carefully designed reactance-compensated, through-line cavity and Arc-Plug® module placement, customer and government test approvals show this design is as good as, or better than, DC-blocked designs. Lightning surges do lots of damage annually. Protect your equipment from surges with Alpha Delta UHF Connector Coaxial Cable Surge Protectors from DX Engineering!

DX Engineering 75 ohm Coaxial Lightning Surge Protectors

DX Engineering 75 ohm Coaxial Lightning Surge Protectors feature a unique design that is impedance-matched to 75 ohms and are virtually transparent to all analog or digital bi-directional signals from DC to 1.0 GHz. Manufactured by Tii Network Technologies for DX Engineering, their patented proprietary coaxial gas tube surge protectors are equipped with an integral failshort mechanism for a power-cross condition, which shunts both the coaxial cables' center conductor and sheath for a common path to ground. The dc breakdown voltage of the protector provides superior protection against transient surges, and yet is compatible with network-powered applications. They may also be used in 75-ohm receive systems up to 1.0 GHz. The protection element is designed to reset after each over-voltage event and the metallic housing of the coaxial lightning surge protectors provides necessary EMI shielding. When properly connected, DX Engineering Coaxial Lightning Surge Protectors are environmentally sealed (15 psi) to prevent the ingress of moisture and humidity encountered in broadband pedestals, vaults and stand-alone receive antenna applications. Full 360 degree Type F connectors provide superior RF performance and tighter connections.
