PolyPhaser Grounding and Lightning Protection
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.

PolyPhaser IX DC Surge Protectors
PolyPhaser IX-1T Data Phone Line DC Surge Protectors are designed to be lightning protectors for 2-wire telephone landline trunks or DC control circuits. They are fully weatherized, modular high-speed digital data DC line protectors and incorporate one T-board for use in high-speed network and DC voltage applications. Their unique design allows them to be used in a variety of voice and data applications. PolyPhaser IX DC Surge Protectors offer fast response times and lower differential voltages and harmonic energies than gas tube protectors. -- Data Rate: Up to 25 Mbps -- Operating Voltage: 48 Vdc -- Turn-On Voltage: +/- 210 volts typical -- Max Holding Current: 400 mA @ +20 degrees C -- Operating Temperature: -40 to +65 degrees C
